Default Re: Warning to All! - Everyone look at this!

Yep, my motor has sheared the rear stud next to the crankcase as well. The front mount was robust enough that the motor was held in fairly well.

Took the motor out last night and retapped the holes to 1/4 20 and I suspect that I won't have any issues.

Yes China makes crap! I think replacing all of the studs with nice 1/4 20 or maybe even 6mmx1 quality stock before the install is a solid move.

You don't even have to redrill the holes to switch to 1/4 20, just run a bottoming tap into the existing hole. [Or just grind most of the taper off of your tap and you have your own bottoming tap] Blue Locktite the new studs.
