I have a 2014 xp1000 and have started experiencing a shutter in the clutch when taking off. It doesn’t matter what gear. I have 30" mongrels and a new epi clutch kit for the size tires I’m running. I have a new belt that has had the break in milage on it. When I put the clutch kit in, everything looked to be in good condition. I marked the alignment on the clutch parts to make sure that it was reassembled properly. I have changed the gear lube in the trans and was in great condition with no chunks stuck to the magnet. Any ideas where to look for this problem?
