I've been going over this bike trying different things to get it to rev from 1/2-3/4 throttle.
When I start the bike and let it warm up and go to ride it,it will pick up and move till I get to high rpms and it will spit and sputter. When I get up to 4-5 gear wot it goes away and it flys.

I have the manual on the bike and been reading everything and still havent fixed it lol. I took off the carb and cleaned it. I've tried various jets and I was thinking it might be the power valve or something. So if anyone had the same problem and fixed it lmk. Oh and I've search in this forum for like 2 weeks now but now I'm out of things to try lol.
