2012 m800 Proclimb piston damage

10000ft · Dec 25, 2012

I have a Boondocker race gas 2012 Proclimb m800. Had it out five times and it has always run great (AFR 11.8-12.3). Today after warming up the sled for ten minutes and going up the road five miles it seized a piston. Looks like the piston became too big for the cylinder. Does not seems to be a lean burn down. I had the same problem on a turbo m1000 and had to stand the skits down for proper clearance. Running 110 octane at 8000ft when it happened.

Anyway wanted a couple of opinions on the piston seizure.

Thanks

TSE..

One or both

To much heat to quick or low coolant.

only the clutch side.

Could have blown a crank seal and caused it lean and just got to hot to quick, but not likely.

make sure your oil mix is 32 to 1 looks lean and low oil mix
