Just wondering if anyone has had a problem with primary clutch bolt backing out
. 99 670 ho did boom,
this week in northwoods called several diff shops none had ever heard of this. found a used tra off of a 02 mxz 800 , said it would work shop put it on , 20 mi later bolt backed out again but didnt go boom atleast
took back , shop put loctite on bolt( which was new when 02 clutch was installed) retorqued, added star washer on concave washer, rode 100 mi that afternoon started making noise at idle( in clutch) took to shop next day said it was starting to come loose again. Had to leave that day back home great shakedown run
Where to go from here

maybe the splines are worn so the clutch is vibrating like mad now therefore backing off the bolt?
it'd really suck if that was the problem.
