I"ve recently installed a new CVtech trailbloc clutch on my 2012 1000XT. After installing on initial test run clutch engages and accelerates fine, no belt slipping but when you let off the throttle quickly (at any speed) the engine braking hits so hard it almost throws you thru the windshield. It decelerates hard enough that it will drag the rear tires on pavement! Anybody have any thoughts on what my problem might be? The secondary was untouched, so I wouldn't think that would have anything to do with it. It was running fine before swap with OEM clutch. Just replaced because stocker was getting sloppy and very jittery at slower speed.
