as far as i know, you can just take out the transmission by itself and u should have access to the fork.

take off exhaust system
loosen the bolts from the engine side and the drive shaft side, remove drive shaft....once youre in the tranny ready to take it off, wiggle it and it should come loose...

see whats wrong with the fork, then when everytying is done, do the reverse process....
have fun putting the tranny back in, lol. mine wouldnt line up to the center. took me me and my friends 20-30 minutes to get it in there.
