hi there , i have a 95 trx 300 which had sat for a while , cleaned the carb out and it starts first time , however when reving it will only rev to half revs and is also making a ticking noise which isn’t promising but it not as bad as a bottom end knock i think , it has been said it could be tappets or timing but the half revs issue worries me , i would be very grateful if anybody else has experienced this and any advice welcome , many thanks sam:smile:
