Man that is no good.You finally finish and this happens.Like always time to do another top.I own an 1989 RM 125 for about 14 years now and has been an awesome bike.Oldy but goody.Good luck getting it back to normal.
thanxs man yea i pieced her together i got tha bike for $80 from my friend and tha guy that had it before him dumped about 3k into it so i couldnt pass tha deal up but actually my bike is a hybrid it has a 90 bottom end with a 89 top end but one good thing is i have 2 jugs so ima get another piston kit and slap tha other jug on it and she will run
