2004 400 Max – Clutch Odd Shifting

I added a Dalton Clutch kit at 4,000Km, the quad now has 8,000Km. The clutch has started up-shifting like an auto gear shift – at least that is what it feels like. The four governor fingers are worn in a bumpy pattern on last inspection. What is going on with this clutch?
I would like to have it (primary) over hauled or find a low mileage replacement. Is there a company that will over haul by mail. (Alberta Canada) The Can Am dealers want top dollar just for stock.
