So having some problems with my 2015. This sled has been a freight train since i got it. Much stronger than most imo.
But all of a sudden it took out 2 sets of plugs within a short period. Sled has 1600 miles.
Decided to pull top end after seeing some scoring on the pto side piston through the exhaust port. At first i figured i just cold seized it, but upon further inspection there is a single distinct score line in one place only. Approx 1/64" deep by eye, 2 chipped rings in line with the score line and a raised edge on the top edge of the piston.
Anyone seen this before? Im thinking power valve came in contact with the piston. Thoughts?
