I have a clutch situation and was interested in any advice from anyone with experience putting a P-85 Polaris clutch on a cat. 2010 M8 blew the spider apart so I will be hunting up a cat clutch for it or am considering the FTX mod to get a P-85. Actual thinking was to put the P-85 on my '14 Proclimb and pass the proclimb primary over to the 2010 (this is the sled my son's ride). Probably cost about 500.00 extra but would then have a rebuildable clutch v.s. the throwaway cat clutch and I do plan to keep the old 2010 for quite a while as the back up sled for sons (and hopefully daughter if she'll put down the ipad!). Anyone have any positive or negative experience with the P-85 on the proclimb/M8s?
