I purchased a 1989 kx80 as basket project. The bike was all apart due to a failure of the a crank bearing. I purchased a new crank, seals bearings and top-end.
Well I got the bike back together and it runs on 1 or 2 kicks. The problem is the bike seems to have no power and does rev out like a small 80 I believe should. Well i want to sell it- but don't want to give someone a bike with major problems. My thoughts is a jetting issue but I was thinking it could be the timing or air leak(bad seal).
the engine doesn't seem to race( zing-zing) it sounds like a tame old pw zinger it just sounds weak....I was hoping that maybe someone could point me in the right direction before i go tearing into the bike.
