Hi Gray,
I have a 2003 YZ450F Motor that has a bad crank in it because of lack of oil issue.:lol: I also have a 2003 YZF450 quad crank brand new that was given to me. Do you know if these cranks can be swapped out ? I was going to break her down and get it done but dont want to waste the $$$ on gaskets til I have all the parts. Thanks for your help :thumbsup:

No, they can't be interchanged. The quad crank has the wrong left axle on it, and is a shorter stroke.
