ive got an 1978 xr 75, when i ride it now it feels like its bogging down to the point where i need to pull in the clutch and giv'er. I dont really kno how else to explain the problem, but theres more to it :S. but, if anyone could tell me what signs tell u when its time to adjust the timing chain or the valves in it, could it need a rebuild? i donno but any help is really apprecaited since its very important to me that this bike is fixed.. thanks for any help
oh yeaa
if anyone who has a manual for this bike, (i think its the same till like 2003 or something i dont even kno) if u could scan or copy a few pages out of it that might be helpful and email it to dylans_really_smart@hotmail.com that would be pretty nifty
