how did you just "check your shifting forks" those are deep inside your motor and if one IS bent which is probably the case, you'd be better off buying another motor vs. paying somone to go in and fix the problem. I might be wrong since a bent shift fork usualy throws the bike back into neutral. AH just PM patrick =)

pulled the motor back out and droped the oil pan and there right there i put a flash light on them and ran threw the gears not spinning the motor over but just engageing the gears watching the shift forks and gears move it all seems fine as far as i can see the 1st and 2nd shaft is kinda hiden but i can split the case to get to it but just want to know what i need first and lol i already did pm patrick

I am having a similar problem with my track bike. Under hard acceleration it bucks a few times in second gear. Check your gear dogs on the shafts. They could be worn but youll need to split the cases to replace them.

LOL.... any stunters want to admit to seeing this?

didnt think so..

sounds more like either a wear and tear issue or a rider that may have slammed through the gears to much with no clutch...



yes romeo.. if you know what your doing you can do that.. when i raced i only used the clutch to pull off the line. but if you are shifting with out letting off the throttle alittle and downshifting from 5th-1st without slowing down... ya you get the point.. rookies

you bought that motor off ebay right?
