I started out with the full Gilomen clutch kit and ECU tune. I’m still running their ECU tune, but have switched all the clutch kit components over to aftermarket assassins.
Basically, I was having trouble getting my rpms dialed in where I wanted them. Also my machine is always loaded up very heavy. So I switched the clutch kit over to Aftermarket Assassins high load helix, Buttershift washers and Billet Primary Cover plate. AAs primary clutch weights are slightly heavier starting weight than Gilomen, and have a different weighting profile.
Now I’ve got it running 8200-8400 rpm instead of 8600-8800. The higher set gave more snap off the line, but the lower set allows more top end speed, while still being considerably more snappy than OEM.
I was having an issue with the clutch making a very loud grinding noise (it sounded like a manual transmission being shifted without the clutch at the wrong speed), when going down hill and just at the point of the primary disengaging. I took it back to the dealer, and they couldn't duplicate the problem, in all fairness to them, they didn't have enough of a hill to allow the vehicle to push the engine in decell, they did check the transmission linkage and change the transmission oil.
I bought the AA cruiser clutch, which included the parts JT mentioned as well as a new spring for the primary and secondary, and installed the slug magnets in the fly weights. The results were great, lower RPM's, much smoother starts, the clunk is gone, but I still had the noise when the vehicle was overdriving the engine going downhill just at the RPM the primary clutch was ready to disengage. I noticed the needle bearing was very dry when I installed the AA parts, so I ordered the tools to disassemble the clutch and needle bearing grease from Hunter Works.
When I disassembled the clutch, to service the needle bearing, I notice all 3 of the slider plates were cracked, and had some ridges in them from the end of the spider hitting them, and the sliders had wear from running against the ridge where they were cracked. The plates are on back order from Polaris until the end of November, AA had plates and sliders in stock, so I ordered a set from them, and Hunter Works only sells the sliders, so I ordered a set of their sliders as well. I installed the AA slider plates and the Hunter Works sliders and the noise has disappeared.
The picture of the sliders are from left to right Hunter Works, used originals, and AA, the AA may work just as good, I didn't try them, will save them for a backup set.
I'm running the Polaris HD belt part # 3212358. Everything else is original on the machine.
