110 PSI both Cylinders

[PowderMiner]

I’m getting a new sled this year and trying to figure out how long to limp the back-up (2009 D8 163, SLP single and clutching) on it’s:
5200 miles total
3rd set of pistons; Never failure just: 1600 update, 3700 new pistons (worn rings and piston tops), and now at 5200 with 110-112psi each side.
Original crank

The sled will be rode by me on poor snow condition days and family rides (let the wife ride her new pro )

What do the engine docs suggest?

What elevation are you checking it at, mine at 1700 ft wide open throttle, 10 pulls as fast as possible is at about 125, stock pistons. Also you may want to compare with a different compression gauge. 110 sounds low if you are below 3500'.

Compression tests on this motor don't seem to hold as much water as they have in the past.


My advice...Fix Kit and 08 head.
