    Yeah this just happened to me also, I will have to get an Easy Out bit to remove the broken stud and then I will replace all of them with higher quality bolts.

    just my luck i got one out then the ezi out broke in the other now i am just p$$$$$$$ed off, tore it all down to see if i could drill it out from the back side nope. so i drilled a new hole about a bolt with away from the old one have to get a tap tomarow and new bolts. think i am going to make a motor mount like sick bikes looks like it should hold up verry well.

    Never had this problem. Could be that replacing these with USA studs is common knowledge in many builds. make sure you replace them all, not just the broken ones. Don't forget the locktite.

    replaced with grade 8 locktight and lock washers, so far so good.
