I'm rebuilding a 87' yz490. Nobody makes flywheel weights for these bikes anymore so I'm going to have one made at a local machine shop.
I've talked with the machinist and I think we've come up with a good plan to make machine one.
Could anybody atach some pics of some production weights. I'm interested how they set them up. Do they screw into the threads where a puller goes? Do they replace the flywheel nut?
Any info would be greatly appreciated!
