My motor screws always walked around, and with loctite I stripped a few and its frustrating.. I switched to the lunsford fat boy motor bolt kit {it was like $7} and never have any issues now, with no loctite... I know it sucks to pay $7 for 2 screws, but they come with concave washers and there all ti, with big @ss heads on them so you can tighten them pretty good...
