just wanted to say thanks for this video i have my highly tuned aprilia rs 125 (144 cc) 58 mm bore running at 1080 F with a custom ignition curve programmed in to the cdi and flying !! the sensor takes all the guess work and countless plug chops out of the equation. (if its too hot at WOT up-jet) thanks for the vid ! steve

Hi man, will be very good and useful if make a video where we can see the changes of the exhaust gas temperature, when you make different carb settings. I mean the changes of the temperature according the quality of the fuel mixture... In my opinion, this gauge will be helpful when we make the carb settings....

Hi thanks for your info now i have a good reference. I run my speedlight 120cc. 2stroke on 107 CHT and 590 EGT degrees Celsius. On full throttle. Variation of a few degrees depending weather conditions. I'm using the same devices as yourselves. Nice video as always .grtz from belgium

Would be interesting to see you play with jetting to see how it responds to lean vs rich mixture, and whether you could actually increase performance or mileage respectively. And show in action how this could be helpful in dialing in the carburetor from start, as well as using it as a gauge on when the jet should be changed due to seasonal differences in weather, etc. Also, it would be nice to see an alert (red LED, beeping sound) when it hits danger-zone-.. if the Koso supports this.

@@insoninenine8749 I've mentioned it in other videos, but haven't done anything specifically about it. I can sum it up very quickly. EGT has been an incredibly useful tuning tool. I watched CHT for years and now I don't pay much attention to it. EGT gives a much better idea of what's happening at the moment. The combination of EGT and CHT can prove useful, but if I chose one it would be EGT. I don't really tune for fuel economy, but you can see when it's getting hot enough to worry about the piston much better. It makes identifying lean or rich spots in the throttle so much easier. Highly recommend for 2T tuners.

Thanks. Brent

I enjoy the channel. Thanks for sharing: the tips are practical and insightful. No point trying to get absolute EGT temperature down to the last degree - it will depend on the engine, sensor itself, placement and other things. Comparing temperature with other setups to replicate the jetting based on temperature might not work. What will work is to plot the EGT against RPM to see if you can lean it out more or already over the hill: if temperature goes up as rpm increases - you are on the rich (safe) side. If the temperature starts dropping - you should check your jetting for that throttle position. Nothing is of course black and white with 2 strokes unfortunately. But if your sensor is calibrated - it will help to get an idea of what’s going on. No need for EGT to be able to measure - at 1200C - your melted piston would tell you that well before the sensor could pick it up :-) Next one to try is the lambda sensor. I have never used it on anything less than 125cc and it would be great to see if someone gave it a go.

But if you do it on a surface that was well cleaned (I used an angle grinder to get to the clean metal and make some asperities for the solder to have good grip) and use the correct flux, it gives a nice weld that just needs a bit of filing to get rid of the small irregularities. Since I didn't have access to nor know anyone with a TiG/MiG welder I bought the oxypropane brazer for an easier job. Using a normal propane torch works too, but it takes much more time to melt the solder, After that, a bit of high-temp paint over the weld and you're all done. :) And since silver solder only melts at around 650°C, for a weld that's square in the airflow you won't ever really risk melting it, even when the bike is stationary.

Usually there's 0.01mm difference from one letter to the next. So a B should be 0.01mm larger than an A. The only way to really know what's what is to do precise measurements of the piston and the bore and come up with piston to cylinder clearance figures. That said, usually when I bother to try to get the correct piston, the clearances change so rapidly that the 0.01mm doesn't matter in no time. Some just hand hone their cylinders. It's all I did with the TPR and new pistons. I used Scotchbrite maroon pads. 49ccscoot.proboards.com/thread/11175/simple-cylinder-cleaning-honing-techniques

Can't honestly recall exactly what I used. I see other vids showing silver solder used, but you'd be better off to consult someone more knowledgeable than me on that part. Just get yourself one of the compression fitting styles if in doubt. Then you need a hole the correct size and you basically clamp it on. Super simple.

Pretty cool to see these finally being used to help tune 2 strokes! I've been going by EGT for years now and it's never let me down. There's certain times and places that you just can't really tell if your engine is leaning out or just a hair too fat. This method is failsafe way to learn what your engine is in need of and yes helps you prevent catastrophic engine failure from detonation if you can't hear it or it's running right on the edge of meltdown. One would think that any higher end equipment that utilized a 2 stroke now a days would come with a EGT kinda like a lot of Diesels do. Exhaust gases in any engine no matter how many cycles they have are no different than trying to read a air fuel ratio guage in theory they're doing the same thing, in a lean condition it's going to run hot as apposed to a rich condition running much cooler. But these also help you with your ignition timing as well for the same reasons. Great video and glad to see that this technique is being used for your scooters. I run anything from 2 stroke rc drag cars to big ones like in my golf cart, not stock BTW lol. But it's a great tool and it will save you time and money let alone a possible engine in the future when you have one and know what your looking at.

@49ccscoot

29 күн бұрын

Mine runs no thermostat, full flow at all times, and has 2 large radiators so I normally see 100-150F coolant temps. Below 100F will be really cold weather. 150F is gonna be the extreme high on a hot day doing wide open passes. CHT depends some on how effective the cylinder head design is. For example, a 1 piece head shows higher CHT for me than modular heads with more flow around the combustion chamber area. Most of the time I'd say between about 180-250F CHT, but it could go higher. On air cooled stuff it can get much hotter. Depending on the gauge and sender setup, some see over 400F CHT. Most of mine have never ran much above 300F. Again, water cooled aren't getting that high for me though. Water temp and CHT are pretty separate things. They can both reflect engine stress, but coolant temp is a poor indicator there. It should be used primarily to make sure the liquid is cool enough and to look for potential warning signs like unusual high temps that may be telling you there's a head gasket issue.

Pretty similar to an EGT install placement, just with a larger bung. You should use an adapter on a two-stroke to help prevent fouling though. Koso has them. The oil and conditions in a 2T exhaust may foul sensors quickly, so most recommend either an adapter or using them only as long as necessary to tune or both. If you want a way to monitor the tune all of the time, EGT probes are much more resilient. The main tradeoff is that you don't see such a direct indication of mixture.

Dude way overcomplicating a simple process. Jet your bike properly you'll stop burning holes in your Pistons. If your plugs showing pre ignition or detanation retard your timing. Way overthinking your scooter. Had countless two stroke street bikes and mx bikes. Never see any of theses devices on a motorcycle growing up simply because there was no such thing

No not overcomplicating. This is really advanced shit. In europe you can put a moped/ motorcycle on the dyno to get it jetted/ tuned to perfection. They use a exhaust tool like this. Besides most motorcylces are 4 strokes and dont really care as much as twostrokes. Also in the netherlands we have races that are called the freetech 50. You can only use a 50cc displacement but people push more than 22 hp out of a 50cc, you think they did that by just jetting a bit?

Watch the Lectron videos. I've gone all of these years without needing one, till this carb. All of my setup details are posted on the TPR series vids. I'd love to see someone make tuning this look easy since the company that made the carb hasn't had any simple answer so far.
