Re: motor mount bolts
And ignore those who tell you to tighten fasteners after every ride. What a bunch of bull hocky. Tighten them once, check and snug after they have reached engine operating temp the first time...then leave them the heck alone. Any fastener or threaded casting can be broken if they are tightened time and time again. Torque them until you flatten the lockwashers then give them just a slight twist more. These aren't semi tractors or bulldozers. Look at the size studs/bolts you're dealing with then tighten them accordingly.
