***VERY IMPORTANT*** I know you added premix “to be safe” but these are not like Yamaha’s etc. Suzuki CCI (which is their oil injection) directly lubricates crank bearings with oil from the pump. If you run premix only and don’t use the oil injection…or if the oil injection is not working…you can destroy the crank bearings. Suzuki has serious warnings that failure to provide proper oil through the crankcase injector ports on the CCI oil injection systems ON ALL MODELS (excluding TS/TM 400) will cause main bearing oil starvation. Just an FYI.

A friend of mine had a Suzuki gp125 cafe racer and the guy he got it fro INSISTED that he always used the cci/oil pump, explaining why !!.., He had ported it & lightened the crank quite a bit, it went ........ well............... It went from low revs till 6,000rpm okay then it spluttered a bit and BANG 6,000rpm till 10,500rpm was like a rocket or explosion 💥 👌🏼 On/off loads of great 2 stroke power band , and us being 17 years old, it was fast for what it was 💪🏼💪🏼💪🏼 Great times 👌🏼👍🏽

Oil injection system are extremely misunderstood by people and hated in an extremely stereotypical way. I wonder why did the Big Four use them in the first place if 99% of people either break them, neglect them until they break, or remove them immediately, and how it was back in the heyday of two stroke power

Very interesting, thanks for the knowledge.

Crazy seeing all the bikes we grew up with from the little 50’s and 70’s then our move to the 125’s and 250’s as we got older. Thanks for bringing back some of the great memories of growing up with these bikes.

Crazy, sometimes you pick up some of the old bikes from my youth. Makes me smile and remember why I became a motorcycle mechanic and all the fun I used to have getting them going...Awesome

Once the transmission oil leaks into the crank case, it travels, with the fuel/air/oil mixture into the cylinder via the transfer ports. No need to get past the rings. I've worked on engines that had oil leaking past the crank seals and also engines that leaked oil into the crank case between the case halves. When the latter happens, the cases are usually warped. Sometimes resealing the cases works, but usually the cases (in my own experience) have to be replaced or resurfaced (if the deformation is minimal). The engine sounds great. Doesn't sound like the crank seals are leaking and I didn't see any transmission oil sputtering out the baffle. Looks like you lucked out with this one. Let's hope that metal that was stuck in the baffle came from a different piston. Couldn't see it very well, but looked like it could have been the edge of a piston, just above the top ring. Hopefully the piston's already been replaced.

Love the variety of this channel big fan from Liverpool UK

Sickkkkk! Love the vids 2vintage

What a blast from my past . I owned a red one in the late 70s. I would get 5 of my friends on it and we would cruse the trails and streets. The gas tank cought on fire and it burned up on the side of the road. Mine did have turn signals and tail light on it. Fond memories thanks.

I had a Blue one just like this. Turn signals, empty license plate holder under the stop light and a chrome rack on the back. I remember Dear Old Dad and his mechanic friend taking the exhaust pipe off once, getting a nice hot fire going in the fireplace and placing the exhaust pipe on the fire to burn all the oil and carbon out. It always smoked. The only time I ever got it to stop was one time when I made several "high speed" passes on a straight stretch of logging road. Put hundreds of miles on the thing riding around in circles on our 1.5 acre lot. Fond memories for sure....

My family has been in the motorcycle business for 1/2 a century, and a lot of times, when one of those mini bikes would come in, he could take a piece of all thread and run it down the pipe, and more often than not, a dirt dobber nest would be in there and after that, they would fire right up. Great watching these videos.

I just worked the set up the Mecum Auction in Glendale a few days ago and they had a couple of these in their collection of bikes that were gonna be auctioned. It was amazing getting to finally see some classics up close.

Cool little bike! The back end had a taillight and those brackets on the grab bar are for rear turn signals (the front has holes for turn signals as well) ... Awesome find!

Another great video for me to watch in the uk. I look forward to every video that comes out especially the will it run one…. Keep up the good work. Absolutely amazing channel 👍👍

Someone must have thought it was seized with the exhaust being blocked so they added the oil to the top end lol

Sick dude! I have a 74’ RV125 with a TS185 swap and it’s cool. They’re very VERY loud bikes though 😂.

I had a simalar issue with a 4 stroke Chinese engine. Looks like it had a bit too much oil in it, some older guys used to fill up the cylinders with oil if they were gonna sit for a long time so they didint seize up. But you never know!

Your killing it man:) awesome video 🤘🤙😎

In England, blinkers were optional in 1970. Dunno about USA laws though... Back light unit needs replacing though. If you can't get the original Suzuki unit, it shouldn't be too difficult to adapt something else to fit though. Love this project... Right up my street! 🙂👍

Great job as usual! Love your vids brother!

My grandpa owned this bike and I have fond memories of riding in front and holding on to the handlebars while we cruised the back roads. It had a back tail light and blinkers.

Should take a torch to the muffler/baffle and then fill the exhaust with gas and set it on fire so it burns all the crap out..sounds sketchy I know but I’ve done it to a few 2 strokes and it works well

Been watching Joe's channel for years. It's my favorite because I'll see stuff go up on marketplace and just know I'm gonna see a video on it😂 live too close haha

I had a Suzuki Grasshopper 50 when I was a kid. It was similar to that bike, and it was a 3 speed automatic. Great memories on that bike as a youngster.

That oil shot was epic 🤣🤣🤣spat my juice out laughing 👍

Really nice vintage 2 stroke, just patch the seat; leave the original cover. Great Job!

A kid down the street had that exact bike back in the early 90's, it was just as ridiculous back then as it is now lol

i have a Suzuki RV200 from 2017.... its like looking at its granddaddy. great little fun machines

I had that exact machine when I was a kid, I used to drive it all over the race track, they are decently fast for a 90

Nice video mate, good to see your working on bikes again.

This engine looks exactly like the engine on my old Suzuki K50. I bought the bike in parts and assembled it when I was a kid. It really sparked my interest in working with bikes. Nice project! 👍

Good job that was definitely worth saving

Had a 1973 RV 125 . Rode the hell out of it . Beware . The kicker is weak be easy on it . Slam on the back break and it will roar leaving a big black streak in the road . These are rare , unfortunately I no longer have it . Keep that one .

We had the RV 125. It had 5 gears. When I was a kid I had it going 70mph. That baffle in the muffler comes wrapped inbaffle material. That's the carbon you found. What's left of it. They came with tail lights, turn s8gnals, plate frame. Road legal bikes. Ours had a tach. The 125 was designed better. Carb behind the motor. Whole frame. They had buddy pegs to. It lasted a long time. We beat that thing. Lol. Battery not needed. Not battery ignition. It worked turn signals while idling at red lights.

That was a cool episode. I love the old-school two strokes. When I was a kid, I had a 1979 Suzuki DS 100. I remember it had a square headlight. I've never seen any other dirt bikes with a square headlight. Anyway, I miss that thing!

Had two of them on 50 acres with lots of trees and hills. The most fun I ever had on a motorcycle. They will climb anything if you get the front wheel on it. Good job.

Check to see if the horn has an adjustment screw.

What an amazing design for keeping the carb clean and away from the elements (dirt/water) I bet these things ran forever and very rarely broke down well over 4k miles on a minibike is damn near a million miles on a real motorcycle 🏍 🤣 it's kinda like dog-years 🤷‍♂️😝

I need to hunt one of those down this way and fix it up! Didn't know they existed! Wanted to share something you may already know that I just found out within the last 5 years and I've been servicing and repairing bikes for 35! Vessel screwdriver company (japan) makes a JIS #2 screwdriver that looks like the one you use a lot, but it has an impact device that turns counterclockwise 12 deg when you smack it with a hammer. Vessel Megaladora impacta is what it's called. I got the entire kit and it's life changing man. The JIS fits little bike's screw heads like this one 100 times better than a #2 Phillips. Amazon has the Vessel's for a really good price. I have a review up over on the channel if you wanna check em out. Great video man, gonna go on a hunt for one of these little bikes now!

I have a 76 RV90 and parted out a 74 back in my youth that I found in the landfill. There is a light assembly and a luggage rack for the back that tied into the bolt holes on that black loop and into the shock studs. Turns signals were standard on the 76, but not sure on earlier models. Make sure you take the exhaust off and dump out that extra oil.

That's a collectors item, hang on to that thing. Usually people who mainly offroad these things take the signals, rear light and mirrors off so they don't break them. The center case gasket or sealant probably isn't holding anymore, oil for the transmission side of the motor leaking through if that's just straight oil, or maybe like you said, the guy put oil down the hole to keep it from locking up, or it was locked up and he put oil in it. Ken Kaplan probably has all the parts for that bike.

Seen that in the last video and was going to ask about it. love the videos bro i have 6 four wheelers and 5 three wheelers in working on fixing for the past year

Neat little bike. These and Honda trail bikes are fun. It would be cool if it had all it's lights.

Love it! i had one of these when i was a kid, it was so fun!, love what you do in your video's keep up the good work.

I had a pair of RV 225s in high school, rode the wheels of them. Tons of fun super easy to work on.got both with spare parts bike for $350.00. Enjoy, the oil pumps were only real issue. Not fast but fun and steady. Enjoy!

I had one of those back in the early 70s as a young kid. Rode the thing like crazy. Never let me down and it was good in mud lol

Hi Joe, God I remember those things they were pretty cool and okay and deep sand cuz of the wide tires of course I actually had a trail 90 in the metallic green it was kind of like an Enduro but it also had street and trail years it had the switch on the left hand side of the upper crankcase you can put it in neutral and switch it either forward or backward and have gears high or low. The bike you have had turn signals it also had a rear taillight those two spots in the back are for the turn signals. I believe that one could have been street-legal also I know that mine was able to be street legal as most Enduros are. I also had a 500 twin older than that or maybe the same year it was a Titan experimental and it also had the high and low range switch on the crankcase and when I bought it when the guy told me it was experimental you know didn't really believe him but I have not found one like that again! That bike was so damn fast for a 500 in high gear I used to Pal around with a guy that had a Kawasaki 1000 Star Wars custom paint from the factory and I can tell you he could not run away from me and top-end. Anyway Joe thanks so much for the video it brings back so many memories. If indeed you ever run across that Titan 500 in the same metallic green with a high low gear switch on it you better grab it and hold onto it.

I stopped at 12:30 to say that the oil does not go past the rings. I gets transferred thru the transfer ports just like the fuel and air does. You are correct that the only way oil can get in the engine is thru the crank seals.

You could adjust the horn on the back of it at the horn adjuster. If it don't have one. You could adjust it on the center nut to give it more or less play to make it work again.

What are you using to record audio in all of your videos with your helmet on that records your voice very clear with no wind noise ?

I don’t remember this bike from Suzuki back at that time the big deal was Honda Trail 70 and 90 . I went from a 3 1 1/2 horse mini bike to a RM 100 .

I love you videos

It appears the oil injection pump leaked by the check valve and filled the crankcase with oil, either that or too much oil in the trans case will do the same. Try pulling the cylinder head off and see what is going on. There will be a large o-ring sealing the rotary valve case inside the clutch case, if it is leaking, then gear oil gets in, same with crank seal behind the rotary valve. Easier than it sounds to reseal it! You may need to pull the engine to dump the oil from the crankcase so it'll turn over. Use a propane or map gas torch to burn the crud off the baffle & spark arrester. Great video, not much to those. Thanks Joe!

Fun bikes for sure. Always wanted one... a friend had one.. you know the story. haha. Hard to come by. I would also like a KLT Three wheeler.

Turn signals were part of tail light assembly. The holes your referenced on the back are for a rack that goes there.

My uncle bought one just like it when I was a kid in 72.they came street legal with turn signals and everything.

Need to see the peacock/fuel lines and how they’re ran. I have one that someone previously messed with and have no idea how to hook any of it back up

The big issue is that all that oil was totally filthy. That doesn't happen in 2-strokes. Use once and burn it away. Mysterious stuff... The clean oil looks like gearbox oil. (I'm just guessing)... So I was wrong. A fine bit of detective work, feller.

your neighbors must hate you. but i wish i had what you do. good video
