I have a P-85 on my 97 600 twin.
P85-wide roller primary
Polaris gold spring
Thundershift weights
39.4 base weight
4.2 gr. heel
7.6 gr mid
7.6 gr tip
total weight 58.8 grams
a higher base weight would have been better as the mid and tip are maxed out and could use a little more weight in the middle.
weight kit cost $50 on ebay, Clutch was ~$80 on ebay, spring was $20 at dealer.
Price to put spring and new bushings in the rollers and weights in the yamaha clutch was quoted at almost $300 parts only(local dealer).
