I replaced the star detent and pizza cutter . I didn't put locktite on the thread of the bolt that goes into shift drum holding the star detent and shift drum stopper . Could this be a problem.?. I have ridden the bike for about 200miles since doing the repair .Would a hex head bolt (with locktite) replace the Phillips head one? (thought it might be easier to remove next time). the PO had used thread locker and it was so tough to get out, even when I drilled the head off the bolt.
