Either the float is stuck or something has blocked a jet. Start with the jets because it's easier. Remove and separate the main jet stack into Air Corrector/Atomizer/Main, then clean all the parts among them. If that doesn't work, remove the float cover and make sure the float moves freely.

Thanks.. My issue is getting gas past the float? No gas going past the intake gas line to carb??
@ChandlerHowell-VespaАй бұрын
First thing I'd check is that you don't have a blocked fuel tank breather. Loosen the tank cap and see if you get fuel flow then. If the breather gets blocked, it's like putting your finger on the top of a straw and it'll prevent fuel from flowing out of the tank. If that's the case, it's a tiny hole in the gas cap that you just need to clean out with a pick or tiny drill bit. Next, check if fuel is getting through the line. Loosen the banjo bolt (see 3:17) and make sure fuel leaks out into the airbox. If it does, you probably have a stuck float. If it doesn't, you have a pinched fuel line, a blocked fuel line, or the fuel tap is clogged. Most likely, it's going to be a pinched or maybe vapor-locked fuel line.

Good job mate, couldn't you do something with the section just below the replacement piece was fitted. Might i suggest if you need to do a similar job on another vespa in the future that you use an old pair of welding clamps. Or get a cheap pair or a secondhand set and do what I have done you get a piece of tubing that matches that curved shape cut the tube in half, then get a piece of solid round bar that fits in the piece of tubing comfortablely. Then weld the piece of tubing to one arm of the clamp and the solid bar to the other, so when you squeeze the clamp the bar fits into the piece of tubing then try on an a piece of scrap metal it's like a miniature sheet metal press you just keep squeezing it and moving it along as you go. You end up with a similar shape to the shape you have of the legshield edge. sorry to go on as if I'm writing a book but it needs explaining in detail as much as possible hope this will help somehow in the future. I have a two 1960's Douglas Vespa Sportiques that were assembled by the once famous Douglas Motorcycle factory at Kingswood in Bristol no longer around I'm sorry to say that one of which I'm trying to restore.

Why was it over throughing fuel even after you changed the needle
@ChandlerHowell-Vespa6 ай бұрын
It will always spit back a little bit at idle because there's not enough air draw to atomize the fuel. if you have an air filter on the carb, it will catch a lot of it, but reduces the airflow, so you can't reach the same peak RPM's. The 24/24 carb makes the low speed spitback a little worse than a 20/20 would, because the air draw is even slower because of the greater diameter. When the needle is bad, though, the amount of fuel leaking through increases so the messy low speed intake becomes much more pronounced and causes the flooding/stalling condition. The paper towel test is the true measure of whether the float or needle are leaking.

This may or may not be a stupid question but is Quattrinni and other brands like Malossi, etc aftermarket engine makers or just part makers? I’m genuinely curious as a stock Vespa has a very linear and sluggish power band and low peak RPM, where as Engines like this have a powerband and sound more like a Motocross bike. What is it and what are all the different numbers between different kits? It’s hard to figure out this stuff as most of it is in Italian, which ironically I’m part Italian myself, but don’t know Italian lol, but I’m genuinely curious on how you would get a Vespa to run and sound like this. I’ve seen Large Frames even with pipes, carbs, and head and cylinder kits, but those all seem to still have the same sound and power delivery as it would be stock, whereas these Small frames with these engines run and sound more like a dirt bike, with a head kit, cylinder kit, piston, etc. If you could break down what the brands are and what they are exactly, that would be great. I’m interested myself in buying a small frame and doing something to the engine like this, but idk how it all works and If it requires a complete new race engine, or parts from a manufacturer like Quittrini to give it more power and a dirt bike sound and power delivery.
@ChandlerHowell-Vespa8 ай бұрын
Malossi, Quattrini, et al. are parts makers, though they may make most of the parts you would need to build a high performance motor. Actually building a motor that gets maximum performance out of those parts is something you can work on for years and still have room for improvement. For example, the first build of this motor used stock VMA1T cases, which I machined out to fit a 54mm Mazzucelli crankshaft along with the M1L60S and the matching Quattrinini M3 exhaust. I started with an egig one-finger clutch, but it wasn't strong enough and wound up with a falc racing fb-45 clutch. Similarly, I wound up going from a PWK34 to a PWK36 carb to be able to move enough air at high RPM's. That, in turn, increased the red line from 11k to 13k. That motor died when the connecting rod of the crankshaft shattered into three pieces--ironically while cruising sedately at about 35 MPH--and destroyed the top end, crank, and cases. If you really want to start building tuned motors, the first step is to learn to rebuild stock-ish motors. If you can't tear down and reassemble a motor so that it's air tight and matches specs that you chose, then you can throw all the money you want to at performance parts and you still won't get a fast motor, or even a running motor. If you're not on there already, come over the the Not-so-Modern section of modernvespa.com . There's a great community of folks (including myself) who do everything from stock rebuilds to hardcore tuning and everything in between. It'll give you an idea of what you're potentially getting into (money and pain, initially), but also people who are more than happy to answer questions, provide guidance, and get you headed in a successful direction. And as to stock power delivery on large frames...I have a few of those that might change your mind as well. The motor in my GL is built on 150cc LML cases, puts out about 26 HP, redlines at about 10,000 RPM's, and has an incredibly wide power band. There are folks doing 50-70 HP builds on largeframes these days, plus the torque that only displacement can produce, which make my 30+ HP smallie seem slow!

@@ChandlerHowell-Vespa Ah ok, that definitely makes more sense now. Pretty much I just want to buy a Smallframe obviously between 50 or 125cc whatever I can find, and then I want to build an engine like the one you have, or something similar made by other aftermarket performance companies. I have really good mechanical knowledge and have rebuilt engines before, especially on my Dirt Bike, so it’s nothing that I can’t do, but I still more then likely would have like Scooter West in San Diego, CA build the engine for me, and I would just ride around for fun, but want something that has the power and sound of a dirt bike. My Grandpa has a 1962 Vespa VBB 150 bone stock which he’s had since the 1970s, and both my uncles once had P200E’s back when they were in high school in the 1980s, so that’s where I first got Interested in them, but again I’m not too familiar with models and specifics, and especially the aftermarket Performance industry to really wake them up. What would you suggest as a good kit by Quattrini or other Brand but similar kit for a small frame for my purpose? And yeah, I know there’s Large Frames out there that definitely have crazy power bands and high redlines, but I’m not too familiar with those engine kits, as most of the time the videos I’ve seen of large frames with cylinder kits, exhausts, carbs, etc seem to have the same linear and slow power band and low Redline as it would be stock, but then again, I’m no expert on Vespas and what it would take for a Large Frame to really be woken up like that if that makes sense. Hopefully a comparison between these videos will better explain what I mean by a Large Frame with a head kit, exhaust, carburetor, etc sounding and running like how it would be stock with no crazy RPMs, vs one that really is woken up and screams. It could be just there are kits that keep the stock head design vs ones with a different design which I may be confusing the two between, but here are examples: kzread.info/dash/bejne/foyksKiFabTOdZc.htmlsi=l04-QOHc2qeuvElO kzread.info/dash/bejne/ZpuAj5tuc73cd8Y.htmlsi=NZXm8TquSdXqUwNI

@@Duderocks5539 If you want to go REALLY crazy, a Quattini M200S is going to be the absolute beastiest thing you can reliably build. It's good for (theoretically) 44 HP without further modifications. Plan on spending north of $4k just for engine parts to make that happen though, because you're going to need high-end race versions of every single part in the motor, along with quattrini cases and crank. If you have experience building two stroke motors, other than picking the parts, it's nothing you couldn't do yourself with a high level of diligence. These are not complicated motors and really don't even require all that many special tools to work on. Of course, once that's done, you're going to need wheels and tires, shocks, brakes, mounting buffers, and pretty much every other part, plus ideally some frame strengthening to keep it all wheels side down. Plus you're going to find that first might as well not exist and second is not much more useful. You'll probably pull power wheelies in every gear if you're not careful, too. None of which is to say you can't build a screamer of a largeframe. My GL's motor is built using LML reeded cases with a BGM177, 60mm bell crank, vforce4 reeds, and a pwk34 carb. It revs past 10,000 RPM's before it goes into overrun, so barely a thousand RPM's short of the smallie, but has an extra 2,500 RPM's of power band on the low end (so net gain of over 1,500 RPM's) and puts out over 25HP across a broader rev range. It just doesn't whip you neck back as much when it gets into the power and doesn't *sound* like it for whatever reason. And I guarantee that both of those motors you linked to have similar or higher redlines, but in all cases, they have a wider power band because of the increased torque--as you can see in the video of the 306, where he's popping power wheelies in first through at least third gear. The choice of components makes a HUGE difference in how any motor performs. Sure, the smallies have a more modern design and better power:displacement ratios as a result, but don't sneer at the largeframes. A properly designed and built (both of which are apparently harder than they seem) motor can do amazing things, large or small frame. 😁

@@ChandlerHowell-Vespa I’ve seen videos of Smallframes with 250’s up to 300’s, such as the Egig 250 and 300, which is just crazy. What also likely contributes to the slow and linear power delivery of stock engines small and large frame is more than likely the small transfer ports and intake port the more I think about it. It’s like the same concept for example between say two 50cc dirt bikes, a Yamaha PW50 is going to have small transfers and intake, along with no reed, and have a smooth and linear power delivery with no high rpm’s or power bands, whereas a KTM 50 has a bigger transfers and a larger intake, plus a reed. Larger transfer ports and intake, coupled with a reed really is what does the trick with waking it up giving it a far more aggressive power delivery and powerband. Pretty much two different types of 2 stroke engines if that makes sense, with obviously both working exactly the same. I understand more on how the aftermarket Vespa scene is now as I watch more videos. If I were to buy a kit like this: www.ebay.com/itm/313346034050 What would I have to do in regards to the gearbox and cases? I assume you just use the stock gearbox and either modify and port match the stock cases, or buy aftermarket cases? In the case of just buying aftermarket cases, what aftermarket case matches this kit? As far as I can tell, the absolute cheapest it would cost to build a performance engine would be atleast $3K.

@ChandlerHowell-Vespa Жыл бұрын
I swapped the one-finger for a Fabbri Racing FB46, but the plates don't fit the original VMA1T basket, so I used a spare set of plates. I didn't have it adjust correctly here, so it slipped enough that it heated up and was basically impossible to adjust--either dragging too bad to shift into 1st or slipping, or eventually both. I adjusted it way back in last night before I did a test ride of the new front disc and all seems to be better now, but only time will really tell. Also, I only have the stock 250ml of crankcase oil. I found out last night that both the egig & FB are supposed to have 400ml, which means it's not getting enough cooling anyway, so I'll be changing the gear oil tonight.

Reliability has a lot to do with build quality. More powerful motors need higher quality parts, and if you don't pay for that, then they are not reliable, especially clutches and cruciforms. If you're doing touring without a lot of gear changes, then it's arguably better to have a powerful motor, because it won't be working as hard to maintain speed.

Either the float is stuck or something has blocked a jet. Start with the jets because it's easier. Remove and separate the main jet stack into Air Corrector/Atomizer/Main, then clean all the parts among them. If that doesn't work, remove the float cover and make sure the float moves freely.

Mate ,don't grind anywhere near your scooters. or anything you don't want to imbed tiny shards of moltan metal into..... I hate to break it to you but you probably ruin the paint work on all your beautiful scooters ,you'll see it when it starts to rust......damn😵💫
Luckily, it's four humid months since then and no signs of problems so far. That OG Vespa paint is TOUGH. I generally do try to avoid grinding or sanding inside the workshop, but that's so I don't make a mess in there.
Apakah sampai kecepatan 100 kmh?
This motor probably could do 100 kmh, but I never tested it. The motor that's in it now has done 103 kmh, and that's with 10" gearing on a 8" wheel.
You should have cut the floor panel the full length in half then match it with the original legshield, then fit a new piece of metal in the middle it would have saved you having to alter the edges of the existing legshield.
Perhaps, but would also have added a TON of additional butt welding, which I'm pretty bad at. Plus I'd have needed new, wider cross braces and the whole thing would have spun out of control pretty quickly.

Thanks.. My issue is getting gas past the float? No gas going past the intake gas line to carb??
First thing I'd check is that you don't have a blocked fuel tank breather. Loosen the tank cap and see if you get fuel flow then. If the breather gets blocked, it's like putting your finger on the top of a straw and it'll prevent fuel from flowing out of the tank. If that's the case, it's a tiny hole in the gas cap that you just need to clean out with a pick or tiny drill bit. Next, check if fuel is getting through the line. Loosen the banjo bolt (see 3:17) and make sure fuel leaks out into the airbox. If it does, you probably have a stuck float. If it doesn't, you have a pinched fuel line, a blocked fuel line, or the fuel tap is clogged. Most likely, it's going to be a pinched or maybe vapor-locked fuel line. You don't need to do anything like in this other video, but I explain the basic problem: kzread.info/dash/bejne/g51htK6knN29erQ.html Reply back and lemme know what you find to start. Also, did you do anything in particular that might have changed the fuel line or carb prior to the issue?
@@ChandlerHowell-Vespa the previous owner took out the gas tank fuel filter so we just ran the fuel line directly from the peacock to the bango

@@davidelcess6559 That's the "correct" way to do it since there's a fuel filter built into the float bowl.

Ah I hadn't seen this video but just watched it, I'm new to your channel starting from yesterday. I haven't watched many of your videos yet but I'm looking forward to doing so, and those vice grips are similar to mine and what a coincidence or mine are similar to yours whatever way you want to look at it. Not trying to take credit, anyway I don't know if you would be interested. I bought my first Vespa in 1962 brand new in London for £139-00 and that also was a Douglas Vespa Sportique 150 cc, anyway I'll let you get on nice chatting to you happy scootering 😊
I'm always interested in comparing notes on projects and techniques! I got the pliers in that video of the GL from another scooterist I know out in California, who got them from a mutual connection in Seattle. I've since sent them on to another friend and made my own set when I did the Smallstate. You can buy them now, too, but they're like $60, so not worth the price if you have the ability to make your own. I have a bunch of video I shot but didn't edit up for whatever reason. I may have to go back through and see what's worth editing up now that the Smallstate (which has since been re-named the Boo-Badge) is in a stable state and I'm moving on to the next projects. (I just realized I have three in the pipeline, all very different from my usual work!)
Oh did you I missed that sorry, I've just re- watched the video and I see what you mean now. Well at least you made a good job of it and that's what it's all about. 😊

Good job mate, couldn't you do something with the section just below the replacement piece was fitted. Might i suggest if you need to do a similar job on another vespa in the future that you use an old pair of welding clamps. Or get a cheap pair or a secondhand set and do what I have done you get a piece of tubing that matches that curved shape cut the tube in half, then get a piece of solid round bar that fits in the piece of tubing comfortablely. Then weld the piece of tubing to one arm of the clamp and the solid bar to the other, so when you squeeze the clamp the bar fits into the piece of tubing then try on an a piece of scrap metal it's like a miniature sheet metal press you just keep squeezing it and moving it along as you go. You end up with a similar shape to the shape you have of the legshield edge. sorry to go on as if I'm writing a book but it needs explaining in detail as much as possible hope this will help somehow in the future. I have a two 1960's Douglas Vespa Sportiques that were assembled by the once famous Douglas Motorcycle factory at Kingswood in Bristol no longer around I'm sorry to say that one of which I'm trying to restore.
I actually made exactly that when I was doing the Smallframe :D I made mine out of a pair of old vice grips and was able to press in an entire new edge to match up the floorboard with the legshield, because the only replacement floorboard I could get didn't quite match. I thought I'd done a video about fixing that legshield-to-floorboard edge. I must've never finished it, but should dig it out, I'm thinking.
What do you think about BFA/FRT 150 cylinder? it revs high
I don't know enough about it to have an opinion, but I have a ton of respect for everything BFA I've seen, so no reason to doubt it's a quality piece of kit. Longer stroke, seems like the drag racers like it. It makes my motor look cheap, cost-wise. 😂I think a better comparison would be to an M200S, which is similar cost and 44 HP. My first ML160S build used a 54mm crank and turned 13,500 RPM's. The 51mm quattrini crank only turns about 11,500, but at least it hasn't blown up yet. Both of them come on the power dangerously fast--I'm 230 lbs and have to lean way forward to keep the wheel down even in third gear when it hits the pipe.
Does 2 stroke AFR reading should be same value like 4 stroke? 12.7? best AFR?
it should be 14.7:1 for ideal stoichiometric efficiency and 12.7:1 for maximum power.

have you ever converted a 2 port case into 3 port? Especially the old case which there is a hollow section where the third port is going to be made, so the hollow sections need to be filled with metal before we can make the 3rd port
I haven't, but have the original 2-port motor from my VBB that would be a good candidate for it. Plus, I could put a spare 3-port on it since I raised the exhaust port too high on the current cylinder and ruined it. That will be a great mini-project for after the Smallstate is back together.

And all of this is distracting from getting NEW videos edited, plus making actual workshop progress. Thanks for letting me know!
Why was it over throughing fuel even after you changed the needle
It will always spit back a little bit at idle because there's not enough air draw to atomize the fuel. if you have an air filter on the carb, it will catch a lot of it, but reduces the airflow, so you can't reach the same peak RPM's. The 24/24 carb makes the low speed spitback a little worse than a 20/20 would, because the air draw is even slower because of the greater diameter. When the needle is bad, though, the amount of fuel leaking through increases so the messy low speed intake becomes much more pronounced and causes the flooding/stalling condition. The paper towel test is the true measure of whether the float or needle are leaking.

Getting that retaining ring clip back in without loads of blood, misery, and profanity is a state secret... And even I don't know it!
This may or may not be a stupid question but is Quattrinni and other brands like Malossi, etc aftermarket engine makers or just part makers? I’m genuinely curious as a stock Vespa has a very linear and sluggish power band and low peak RPM, where as Engines like this have a powerband and sound more like a Motocross bike. What is it and what are all the different numbers between different kits? It’s hard to figure out this stuff as most of it is in Italian, which ironically I’m part Italian myself, but don’t know Italian lol, but I’m genuinely curious on how you would get a Vespa to run and sound like this. I’ve seen Large Frames even with pipes, carbs, and head and cylinder kits, but those all seem to still have the same sound and power delivery as it would be stock, whereas these Small frames with these engines run and sound more like a dirt bike, with a head kit, cylinder kit, piston, etc. If you could break down what the brands are and what they are exactly, that would be great. I’m interested myself in buying a small frame and doing something to the engine like this, but idk how it all works and If it requires a complete new race engine, or parts from a manufacturer like Quittrini to give it more power and a dirt bike sound and power delivery.
Malossi, Quattrini, et al. are parts makers, though they may make most of the parts you would need to build a high performance motor. Actually building a motor that gets maximum performance out of those parts is something you can work on for years and still have room for improvement. For example, the first build of this motor used stock VMA1T cases, which I machined out to fit a 54mm Mazzucelli crankshaft along with the M1L60S and the matching Quattrinini M3 exhaust. I started with an egig one-finger clutch, but it wasn't strong enough and wound up with a falc racing fb-45 clutch. Similarly, I wound up going from a PWK34 to a PWK36 carb to be able to move enough air at high RPM's. That, in turn, increased the red line from 11k to 13k. That motor died when the connecting rod of the crankshaft shattered into three pieces--ironically while cruising sedately at about 35 MPH--and destroyed the top end, crank, and cases. If you really want to start building tuned motors, the first step is to learn to rebuild stock-ish motors. If you can't tear down and reassemble a motor so that it's air tight and matches specs that you chose, then you can throw all the money you want to at performance parts and you still won't get a fast motor, or even a running motor. If you're not on there already, come over the the Not-so-Modern section of modernvespa.com . There's a great community of folks (including myself) who do everything from stock rebuilds to hardcore tuning and everything in between. It'll give you an idea of what you're potentially getting into (money and pain, initially), but also people who are more than happy to answer questions, provide guidance, and get you headed in a successful direction. And as to stock power delivery on large frames...I have a few of those that might change your mind as well. The motor in my GL is built on 150cc LML cases, puts out about 26 HP, redlines at about 10,000 RPM's, and has an incredibly wide power band. There are folks doing 50-70 HP builds on largeframes these days, plus the torque that only displacement can produce, which make my 30+ HP smallie seem slow!
@@ChandlerHowell-Vespa Ah ok, that definitely makes more sense now. Pretty much I just want to buy a Smallframe obviously between 50 or 125cc whatever I can find, and then I want to build an engine like the one you have, or something similar made by other aftermarket performance companies. I have really good mechanical knowledge and have rebuilt engines before, especially on my Dirt Bike, so it’s nothing that I can’t do, but I still more then likely would have like Scooter West in San Diego, CA build the engine for me, and I would just ride around for fun, but want something that has the power and sound of a dirt bike. My Grandpa has a 1962 Vespa VBB 150 bone stock which he’s had since the 1970s, and both my uncles once had P200E’s back when they were in high school in the 1980s, so that’s where I first got Interested in them, but again I’m not too familiar with models and specifics, and especially the aftermarket Performance industry to really wake them up. What would you suggest as a good kit by Quattrini or other Brand but similar kit for a small frame for my purpose? And yeah, I know there’s Large Frames out there that definitely have crazy power bands and high redlines, but I’m not too familiar with those engine kits, as most of the time the videos I’ve seen of large frames with cylinder kits, exhausts, carbs, etc seem to have the same linear and slow power band and low Redline as it would be stock, but then again, I’m no expert on Vespas and what it would take for a Large Frame to really be woken up like that if that makes sense. Hopefully a comparison between these videos will better explain what I mean by a Large Frame with a head kit, exhaust, carburetor, etc sounding and running like how it would be stock with no crazy RPMs, vs one that really is woken up and screams. It could be just there are kits that keep the stock head design vs ones with a different design which I may be confusing the two between, but here are examples: kzread.info/dash/bejne/foyksKiFabTOdZc.htmlsi=l04-QOHc2qeuvElO kzread.info/dash/bejne/ZpuAj5tuc73cd8Y.htmlsi=NZXm8TquSdXqUwNI
@@Duderocks5539 If you want to go REALLY crazy, a Quattini M200S is going to be the absolute beastiest thing you can reliably build. It's good for (theoretically) 44 HP without further modifications. Plan on spending north of $4k just for engine parts to make that happen though, because you're going to need high-end race versions of every single part in the motor, along with quattrini cases and crank. If you have experience building two stroke motors, other than picking the parts, it's nothing you couldn't do yourself with a high level of diligence. These are not complicated motors and really don't even require all that many special tools to work on. Of course, once that's done, you're going to need wheels and tires, shocks, brakes, mounting buffers, and pretty much every other part, plus ideally some frame strengthening to keep it all wheels side down. Plus you're going to find that first might as well not exist and second is not much more useful. You'll probably pull power wheelies in every gear if you're not careful, too. None of which is to say you can't build a screamer of a largeframe. My GL's motor is built using LML reeded cases with a BGM177, 60mm bell crank, vforce4 reeds, and a pwk34 carb. It revs past 10,000 RPM's before it goes into overrun, so barely a thousand RPM's short of the smallie, but has an extra 2,500 RPM's of power band on the low end (so net gain of over 1,500 RPM's) and puts out over 25HP across a broader rev range. It just doesn't whip you neck back as much when it gets into the power and doesn't *sound* like it for whatever reason. And I guarantee that both of those motors you linked to have similar or higher redlines, but in all cases, they have a wider power band because of the increased torque--as you can see in the video of the 306, where he's popping power wheelies in first through at least third gear. The choice of components makes a HUGE difference in how any motor performs. Sure, the smallies have a more modern design and better power:displacement ratios as a result, but don't sneer at the largeframes. A properly designed and built (both of which are apparently harder than they seem) motor can do amazing things, large or small frame. 😁
@@ChandlerHowell-Vespa I’ve seen videos of Smallframes with 250’s up to 300’s, such as the Egig 250 and 300, which is just crazy. What also likely contributes to the slow and linear power delivery of stock engines small and large frame is more than likely the small transfer ports and intake port the more I think about it. It’s like the same concept for example between say two 50cc dirt bikes, a Yamaha PW50 is going to have small transfers and intake, along with no reed, and have a smooth and linear power delivery with no high rpm’s or power bands, whereas a KTM 50 has a bigger transfers and a larger intake, plus a reed. Larger transfer ports and intake, coupled with a reed really is what does the trick with waking it up giving it a far more aggressive power delivery and powerband. Pretty much two different types of 2 stroke engines if that makes sense, with obviously both working exactly the same. I understand more on how the aftermarket Vespa scene is now as I watch more videos. If I were to buy a kit like this: www.ebay.com/itm/313346034050 What would I have to do in regards to the gearbox and cases? I assume you just use the stock gearbox and either modify and port match the stock cases, or buy aftermarket cases? In the case of just buying aftermarket cases, what aftermarket case matches this kit? As far as I can tell, the absolute cheapest it would cost to build a performance engine would be atleast $3K.
correct me if i am wrong.. I heard that Smallframe motor can go high rev because the engine build is different, especially the opposite crank side is not clutch but a pinion gear, and perhaps most parts are lighter.
It's look your mainjet size is too big
Main jet size wouldn't cause flooding when stopped or at low RPM's. If the jet stack wasn't screwed all the way in, it might cause behavior like this, but maybe not even then. In this case, the main was actually starving at WOT until I drilled my float passage.
Its not main jet i think it is the flot ball leavel needs to be refixed that will avoid o er throughing.

Thanks! The repair has been holding up perfectly for over a year now, so definitely a win for me!
Need help fixing it? If you're using a SI carb you need to upgrade the fuel tap. Stock vespa ones flow really poorly. The SIP fast flow tap flows great and fixes the problem. If you are using a big carb though you almost certainly need a fuel pump
The issue was not the tap (I've run nothing but fast flow taps for years). It's a si24/24 with about a 130 main jet. The passage from the float bowl to the jet stack was too small. I drilled it out to 2.5mm and that fixed it immediately. If you run a main jet larger than about a 125, you will see this problem on undrilled si carbs. I thought it was already drilled, so was surprised when I looked at it and realized it was still stock.
SAFETY THIRD
Most people who know me are happy to see it's now rating that high! 🤪
Soft seize?
HARD seized. Wheel locked up at 70 MPH. my quick connect failed and was only letting a trickle of fuel through. CHT was only 280F. Lack of lubrication is what did it.
@@ChandlerHowell-Vespa wow, bet that woke you right up. Amazing how something so seemingly simple and bulletproof as a quick connect on the fuel line could be so disastrous. So the CHT didn't have enough time to climb, eh. I wonder if an EGT sensor would've been able to give you the heads-up in time?
I like what you've done there. I need some indicators for my new one. I'm looking at buying some wireless ones though with a magnetic back. Just need to find some.
I looked at doing something like that, but couldn't find anything I liked. The little lights in back are really bright with a nice wide field of view. I'm considering replacing my front lights with more of same. Definitely get some signals, though! I hate riding without them now.
damn that sounds good.
Do you have to open or mill the case for the Reed valve intake?
The M1L60S is a direct intake cylinder, so I don't need it. It was actually a bonus that the case inlet is closed off by default.
take it easy on this one!
LOL! I'll do my best...same as always!
beautiful bike! and appreciate the write ups on the forum!
wow, what a nice mess. mazzuchellis have a decent reputation too. maybe a manufacturing fault . At least it wasnt a high speed fail which couldve locked you up at max speed.
I think the crank just wasn't up to the task at hand. I've used Mazzu cranks almost exclusively in my builds, but nothing with this much power. I'm on my second Mazzu P200 bell crank in my LML, but it's only 27 HP. The first one failed when the pin slid back into the web a couple millimeters. Luckily, it didn't do any damage other than to itself. New build is going to use a Quattrini crank that's purpose-built for their cases and claimed to be good for 40+ HP.
SIP and Scooter Center thank you for jump-starting their fiscal year. That engine's good for little more than bragging rights now!
nice disc hub assembly. Smallframe is shaping up nicely
Other than the banjo bolt, I was really impressed with how easily it went on. That's going to be a tricky one to fix, because there's just not much clearance between the caliper and the hub.
@@ChandlerHowell-Vespa fabrication skills will be tested,should be interesting 👍
is this 3 ports cylinder?
Yes, the BGM is a 3-port cylinder. The motor in this bike came out of my Sprint Veloce. The original 2-port VBB motor is on a shelf right now.
@@ChandlerHowell-Vespa i see, i thought you add 3rd port to the original case
@@SuperMonik Not this time :)
sounds clean, one finger clutch shouldnt be slipping this hard. Have you ever been in contact with egig ? What oil are you using ?
I swapped the one-finger for a Fabbri Racing FB46, but the plates don't fit the original VMA1T basket, so I used a spare set of plates. I didn't have it adjust correctly here, so it slipped enough that it heated up and was basically impossible to adjust--either dragging too bad to shift into 1st or slipping, or eventually both. I adjusted it way back in last night before I did a test ride of the new front disc and all seems to be better now, but only time will really tell. Also, I only have the stock 250ml of crankcase oil. I found out last night that both the egig & FB are supposed to have 400ml, which means it's not getting enough cooling anyway, so I'll be changing the gear oil tonight.
haha, guess its fast enough. I dont go in resonance in first ... the m1ls is very powerfull!!
I've learned that lesson more than once now! It's amazing in 3rd, though, from 45 to 70. I've only had it up to 80 MPH, but it should be good for a little more than 90.
@@ChandlerHowell-Vespa 2. and 3rd are the most fun everything 70+ is lightspeed on a vespa what gearbox are you running ? I read you had egig 5finger, i have the same but only 20rwhp, what kind of oil u use?
@@I3igTasty I'm running stock VMA1T 4 speed gearing. I get over 10k RPM's before I run out of power with the M1, though. 2nd is almost as bad as 1st for wheelies when it gets on the pipe, even with my whole body out over the handlebars. :D
@@ChandlerHowell-Vespa yea 1st is impossible at 20whp i lay on my handlebars and still almost flip, if you got money to spare i recommend falc racing 4th gear. I am building a 244bfa right now.. gonna be real scary
@@I3igTasty Short 4th might make sense. I don't really need a smallie that goes 90+ MPH
Ohhhh!!!
the joys of tuning🤣.....but when you find the sweet spot that smally will be fun.
It's a freakin' BEAST when it's say up better. Like "wants to wheelie in third" level beast.
smart carb time.
I thought about it, but a thousand bucks for a carb is a bit much. I'll go back to square one, find the right needle diameter, and work through it from there.
@@ChandlerHowell-Vespa dont go smart carb, 180 main on pwk is ultra rich go 165-170 for testing this will be a beast, but clutch is weak, heavy slip, what are you running ?
@@I3igTasty The clutch was an egig one-finger. Supposed to be good up to 35 HP. I replaced is with a Fabbri FB45 tonight, so hopefully it's up to the task. I also swapped out the carb for a Keihin Air Striker 36 and on a brief test ride (In dark & rain), both of them seem to be solid improvements.
Malissima carburazione
Do you still have a reed valve Stella? How about a pipe such as a PM Tuning? Would be interested to see those results also.
Have the PM Tuning pipe on my Stella motor, but it's running a PWK34 with VForce4 reeds. I have a Venturi/Bellmouth for it, too, now that you mention it, so I could potentially replicate the experiment on there. I put it on but almost immediately took it off because it made that thing LOUD, even compared to the PMTuning exhaust.
its a pts or special?
It's a 1966 Allstate, the Sears branded smallframe
I love vbb1964 ☺️
125cc 150cc 177cc???? Thank you love it.
It's a long stroke 177, so a 187. The motor is a three port out of my Sprint V and I've done a lot of work to it. It puts out about 18 HP right now.
It’s strong engine? I may buy one ready on Vespa 1963 but I worries a bit I really don’t know if it reliable for long trips.
Reliability has a lot to do with build quality. More powerful motors need higher quality parts, and if you don't pay for that, then they are not reliable, especially clutches and cruciforms. If you're doing touring without a lot of gear changes, then it's arguably better to have a powerful motor, because it won't be working as hard to maintain speed.
@@ChandlerHowell-Vespa Thanks still looking for one .
You could try the wee trick Whiteone racing uses to to hold filler on if you have room. Please feel free to remove this post if the link to above offends... kzread.info/dash/bejne/hHhh0bKPnrXdXZc.html Jim 🏴🙂
You're a candid guy, not everyone would admit to that error, which by the way ,most of us have done. Not sure if you've heard of the Buzzwangle tool for measuring timings? It's a great piece of kit. Demonstration videos are on KZread. Jim 🏴🙂
I'm familiar with the Buzzwangle. I use a plain ol' inclinometer and just do a little math to get the same results for a fraction of the cost. The mounting piece that screws into the flywheel is nice. I use a couple of neodymium magnets stuck to my inclinometer, which can get knocked loose if you're not careful.
@@ChandlerHowell-Vespa Thanks for the reply, they are expensive, but I love mine. I also bought it because it supports fellow scooterists.
@@ChandlerHowell-Vespa I also use Scooter lab's budget version of a leak-down tester , as can be seen in their KZread video. I use it in conjunction with a 28mm carb manifold.
@@jimsregaturntableshifijukeboxI don't know how much more low-budget it could get :). Other than the redundant ball and check valve, the whole thing cost me less than $10 to make.
@@ChandlerHowell-Vespa I like your version too, was just saying that's another option. I have another more complicated version similar to yours tucked away. 😉🙂
