I am a question. I wrecked my bike little over a year ago. I replaced the right handle bar. I put everything back on right. Now it has been going on since then, maybe before that, i cant remember now. I will start the bike and I usually let it warm up before I take off. Well about 20 secs or so the bike starts building rpms, like up to 2500 rpm, then I will twist the throttle foward and the idle goes back down to normal, sometimes a few more times of twisting the throttle foward, although if i twist to hard foward the bike will stall. Otherwise the bike runs tits. IS this a simple throttle cable adjustment?
