Happened on the 23rd of January. Cruising at 50mph and it just died. Coasted to a stop. Engine would not turn over with pull or ES. Towed about 10 miles. Waited for an hour for my friends to come back with the trailer. Hand strapped it on to my trailer, that took about an hour. Dropped it off at the dealer. PTO side cylinder and piston totaled. Cat came back and said they are having a rash of faulty injectors. Dealer replaced everything on the PTO side but Cat refused to change out the MAG side injector, which seams very stupid. Rode the sled 3 hours before this happened. There were not any signs. No hesitation. No bogging. No nothing. Just coasted to a stop. Got it back this past Friday. I have put 70 miles on it since I got it back. No issues so far and God willing it stays that way. Been riding cat for 40 years and I'm not gonna change now. Needless to say I was extremely shocked and disappointed when it happened. It is only my second new sled from Cat, my first being an '88 ElTigre' 6000. My dealer was pretty quick on the turn around and I really appreciate that. Many comments on my Youtube video of others with the same issue.
