Dealer lapped crank and put locktite on and before we loaded it up, it's brand new, the key sheared. He says that If I want, I can have a YZ450. I don't know what to do. I would rather have a WR but everyone acts as if there is no guarantee that a new key will solve all the problems. Are they making a different key now to fix this? Should I go ahead and get the YZ? HELP!!!!!!!!!!!
