I've got a YZ400F, and I have a flywheel weight that I want to install. I removed the stator cover, and the detents in the weight align with those of the flywheel. Two of the four holes in the weight align with the two in the flywheel, but i don't know how to attach it. The holes in the flywheel aren't threaded, even if they were the supplied bolts aren't long enough. Pics of the weight for reference.
