I have a honda trx450r and i took the shirft fork out for 4th and 5th and i sent it in to get it fixed and when i got it together i took it out and right when i hit fith gear it took out the shift fork again, so i sent it in to get it fixed again and the guy doesnt know whats wrong, he thinks it coulda jumped out of gear and broke it but he really doesnt know, so any help will be good thanx
