I have a 09 M1000 that took out a cylinder(pto side).Problem is I took it to the dealer and he replaced the cylinder and piston and sent it home.About 15 min ride it died but it fired back up and I got it back to the yard.Pulled off pipe and looked down the y-pipe and new piston and cylinder and destroyed again!First time he blamed my fuel!I have only ever run farm gas with octane boost,I know it sounds bad but it has just shy of 2000 miles and never missed a beat even after I did some mods at 700 miles(slp y-pipe,pipe,hi flow intake,v-force reeds,dynaport power commander 5)and it was bulletproof till I put some town gas in(premium)and it run a little odd after a ride!Pulled plugs,mag side were dark brown pushing black,pto side electrodes were missing(jagged edges not melted)some scoring in cylinder not horrible,replaced plugs ran perfect for about 3 tanks of gas then died.Pto cylinder totally destroyed,mag was perfect.I told dealer I thought it might be crank seal because how fast it went from running perfect to dead but he tried blaming my fuel but I said if it was det it would have showed up on both pistons!So he replaced wrecked cylinder and piston and put in 100:1 oil in tank and 50-50 of 111 octane premium blend gas and 15 min later its done!!Any ideas?I still think crank seal and now he says maybe injector or oil pump!Smokes like crazy and uses oil so?
