Re: Warning to All! - Everyone look at this!
most of the problem of braking motor mount bolts, or them coming loose all the time starts with the chain and tensioner, if the chain is not lined up true it binds on the sprockets, since the tensioner is solid, not spring loaded, the binding makes the chain overly tight and the solid tensioner can't give any slack, so the force is going to pull the motor side to side in the frame. this brakes or stretches the studs. grade 8 bolts are great, untill you need to drill a broken one for an ez-out. grade 5 is strong enough and not to hard to drill if the need arises.
