ok so i have to adjust the screw to make it more richer. Yes, i did took out the plug and the tip of it appeared to be white. I ran it for maybe 20 minutes at such condition. Could the piston already be damaged? Also what do i do if i get uneven RPM's it goes up and down by 2 bars, and you can actually hear that its not running even. THANSK!

Hello guys, recently i have installed a 100cc bore kit for my 49cc chinese scooter. Followed the video on YouTube and carefully installed everything in order. The only thing i haven't used was torque wrench, After the whole procedure was done, i have e replaced the engine oil. The problem is that now scooter runs very hot, the top lid is super hot to the touch and the scooter is worsen in performance. Maybe i need other parts to make this work? What could be the problem? Could you guys tell me what to check for? Thanks!

This is the bore kit ive used.
