Thought I fouled a plug but found out otherwise. Pulled pipe and piston is wasted. Took it in to service at local dealer and they told me the wrist pin clip broke which obviously led to major destruction. Heres the kicker, only 1000 miles on sled and 1 month out of warranty. Hopeing AC will step up to the plate and take care of it, but not very likely. Anyone ever heard of this on these machines. Any insight would be great.
