Just to say but from all the XT 125cc I've tried there all out by 3-4 mph

Are you sure it's the fuel gauge lol?

No its true that they can I've had 89 out of mine and that was GPS my speedo says 93. And it's stock apart from the handle bars

What's stock tooth rear sprocket number as every one seems to think that only way I can achieve 90 is with a smaller sproket
