Take compression readings and see if its past the Service limit.

Just hook up a Battery with a Remote Starter to the Starter for the test.

Don't need E-Box, Intake nor Exhaust Manifolds. Just Cylinder Head. Can do it outside of Ski.

I've had SEVERAL engines apart with perfect compression and loose lower end bearings. I've also seen good compression readings and VERY worn cylinders. If it's something I'm keeping, the engine gets completely torn down for inspection and all new gaskets and seals.

Is that a Powervalve Cylinder?

If so, those might be $200 dolla Forged Pistons; jus' sayin'...

More like oil residue than blowby Certain oils regardless of quality, will leave a residue when flashed off.
This is common on water cooled two strokes.

With the quality of that picture, I really don't see any rings, even with readers on lol.
