Default Re: Snapped Rear Mounting Studs (3rd time!)

Is there any space between the frame and the mount before you tighten it? In my experience if you have to pull the motor to the frame at all when you tighten the mount your studs are going to break.

Try adding a pair of 1/4" flat washers between the mount saddle and the block next time.
Straight tubes suck, the beauty is in the bend.
