Buying a used 22 Khaos 850 2500KM. Anything to look out for?

[440revNL]

I'm planning to sell my 24 Freeride 850 as I just don't like the feel of the Doo for the deep snow sleds.
So a friend of mine is selling his 22 Khaos 850 155 2.75 with about 2500KM. Is there anything to look out for on the 850 with that many kms? I'll be checking the compression before I would buy it, but is there anything else to look under the hood, besides obvious damage to the body.

By the way, what is the good compression for a Patroit 850na?

I'm looking at buying it to tie me over for next season, then hopefully Polaris will release the new generation sled and I'll snowcheck one and get a 9R!

Other then what you've already mentioned regarding compression then looking for leaks and squeaks and wear and tear like any used sled. The 2022 850 NA Patriot is a pretty bulletproof engine in my experience. All depends how it was ridden and maintained. The 2.75 track is not known for long term durability though so check to make sure its in decent shape.

The service manual I have didn't actually specifiy a compression level but did state:
"Test both cylinders under the same conditions using the same
compression tester. Verify the compression difference between
the cylinders is ≤ 15%.:

I've heard 130-140 psi new but around the 105 psi range it needs a top end. <disclaimer - I'm not a mechanic.
