How many km's / miles do you have on your xp? Just hit 3000km on mine end of last year and wondering when is the "right" time to rebuild the top end to stay mostly worry free. I am thinking one more season but Let's hear how many km everyone has.
Was there scoring on the intake side only?First, what year sled?
Second, even by doing things like compression checks will not always reveal scoring, or crank run out issues.
3000km, should be good. Altough on my 09 I happend to pull the head off at 3500km and it needed a new top end in a bad way. Likely the result of snow injestion, although I am not convinced.
Ride it till 5000. Throw a set of pistons in then. Ride till 7000km. Then replacev motor. That's about what our xps have been going for

your sled has already eclipsed 10,000 has it not? One set of pistons? Shut your hole

heavily on the intake pto side, but there was scuffing on the exhaust side as well. When I say I am not convinced it was snow injestion is because only one side was bad. Other side was good.
I don't want to rain on one's parade, but this has nothing to doo with KM's or longevity. I definitely was a bad environment for that piston at sometime. Wash looks like it should be reviewed (since it is a tad leaner than left)
3000k is a good time to swap out the pistons. I let my REV go for 4500 and the piston skirt let go and grenaded the case. Compression was still up there, Pistons still had the machine marks and the moly on them.
$325 is cheap peace of mind. Get a set of MCB dual rings from Kore and don't look back.
