This Polaris primary clutch has 07 weights and a purple spring. It has decent cam arm bushings and rollers, but has some play in the center bushings. It still functions fine. It has the standard 30mm 1:10 tapered bore, and can be used on many Fuji twins and triples as well. Shipping is only in the lower 48; unless you are purchasing through eBay's Global Shipping Program. If you are in Alaska please contact me before purchasing to check on shipping options. Thanks, -Paul
