Ok, First off. If you have removed your rear wheel you are 5 or 6 minutes away from having the belt off, no way in h3ll is it worth almost $1000 to have dealer change it. I took measurements off of the old and new belt, could not find any difference. I installed the belt and went for a ride. The new belt did absolutely nothing, no difference at all. A complete waste of a $160 diagnostic fee and a $260 belt.
