They are now available  for the 500 HO through Main Street Cycles. They texted me today.

Installed the Airdam clutch kit I got from Main Street Cycle tonight. If you can only do I modification, this is the one. The Jerky starts and the slow speed jerkiness are gone. This is how it should have come from the factory. Totally smooth at any speed. I got a spring and 6 clutch weights. I have stock size tires so I clocked it at B2 which is their recommendation. Much much better. It no longer feels like a compromise. You could order the components individually from the CanAm parts guy and save some money. Cvtech  Trailbloc Primary Weights 10 grams 0901- 7103 $27.10 and CVTech trailbloc primary spring 200-1200 0951-1016. They are currently  out of the spring, but the 0951-1016 spring is available other places for slightly more.

Good..glad someone knows what they are doing. Wish CFM would take note.

Has anyone been able to find the 0951-1016 spring?  Can't seem to find it anywhere.

You can order springs directly from CVTech but that number looks to be no longer stocked.
