I had some great finding this weekend that I hope will help alot of RXP, RXT and other super charged owners. I took the air inlet pipe off to install the Power pipe. While that was off I could look down and see the fins (Or veins) of the SC. I took my thumb, index finger and middle finger and put some force on the SC impeller and it turned with not much pressure. HMMMM sound like my cluch could be slipping. This was just a quick test but I am sure you can get a tourqe wrench and proforman the same test. With 77 + hours on my stock cluch I will be sending it to PPG for the fixed. I just hope they have the Vortex SC impeller in so that can be added also good luck and check them cluches. I am sure no one wants a SC cluch to fall apart in the motor.

why not send it to Riva? Don't they offer this type of service?

The reason why I am sending it to PPg that is because they carry the Rotax Racing cluch. Nothing aginst Riva. I am running Rivas Block off's Sponsons, Grate, and air intake along with PPG's Trick up Solas. Both have povided we wiht good parts and in cobonation of the two they have my ski running good just for some bolt on parts.
