I always check ring gap in the new cylinder before putting the rimgs on the plnew piston. I have more than once had to dress/grind the new ring ends so the gap was big enough. That way i didnt have to worry about them expanding when they get hot and binding in the cylinder and destroying the whole top end. Just a recommendation for next time. Heck you might have done it and just not shown it in the video. Good video and im sure itll help someone in the furture.
It's not a bad idea to check the ring gap, but honestly, I have never had an issue with a TB kit. Every time I check them, they are always within spec. That is one of the many reasons I recommend them.
Stock carb? Any work to the jetting? I have a stock klx110 with a yoshi pipe and I get bogging. You can run the big bore/pipe with the stock air box and stock carb???
Do you have the stock airbox? If so, then i recommend running the stock jets even with the yoshi pipe. This bike still has the stock carb and air box. With the stock airbox, we kept the stock jets. I tried a few bigger jets in it, but it would bogg at full throttle from too much fuel. I talk about it around 54:00. Recently, I modified the stock airbox and took off the rubber boot that goes into the frame to get more airflow. I put in an 82 main jet, and now it rips. Here is a link to a video of it shooting flames 🔥 ru-vid.com3jKMt_QOOZE?si=WTtwbX3fSUlflWBA I personally recommend a modified stock airbox. If you are doing the 143cc big bore kit, it brings them to life. Just remember you won't need to jet it for more fuel unless you are giving it more air.
