Hi guys,
i have a beta rev 3 2007. i'm only a novice rider its my second bike, i love the bike to ride but i feel a little disapointed with it because its seems to be one problem after another. first it was the carb, that seems to have stoped but now i hear a knocking sound when giving the bike throttle, only when moving in the like of fourth gear, not any lower. when i wheelie it knocks but when im only playing about in low gears its fine, but as i said in the higher gear it knocks CAN SOMEONE GIVE ME SOME GOOD NEWS PLEASE.
