I installed my STM clutches today. All I can say is so far I am happy with them the way I received them. Thank You Swingarm1 @ Tagteam for the great service. I installed the rage 6 with secondary. I put about 10 miles on it on blacktop. This was running between 50 and 60. Right before I got back home I opened it up and it ran a solid 80 MPH. Clutch temp was running less than 140.

With New belt

Old Clutch. It is missing the Teflon washer. I think it was missing from the factory. You can see a groove cut into the sheave.

Thank you RZR forum for all the info here. I have learned a lot here in a short time. Lots of good people here.
