Bobby, I commend you for taking the time to properly gap your piston rings but I don’t think you positioned them correctly in the bore (vertical height wise) to get the correct reading buddy. You can gap a ring at the top of the bore but remember the taper will always be smaller (thus a tighter gap) lower in the cylider. Check that the gap should be measured with the ring positioned just above the ports.

How many times were the crank bearings greased throught its life

Hey man, looking into doing 600 carb rebuild, noticing piston projection in the manuals to determine gasket thickness. I haven’t started yet, but would you just order standard everything, if the cylinders are usable, and not worry about projection, or is this a really sensitive measurement that needs attention

@bobbyrebussini1466

Thanks man. Well the purpose of honing is to allow tiny tiny channels for oil to live it. 2 strokes don’t need rings to “set” as in like a Chevy 350. No engine in history is mirror finish cyl wall so I wouldn’t try it lol. You’re not even honing nikasil you’re just cleaning out the carbon from the crosshatch

The level of wear on this engine is no surprise. It makes bug torque at low revs and 160bhp is no slouch from 800cc. High revving four strokes won't get close on power/wight and anything big enough to get the job done will use more fuel.

Never been a fan of synthetic oil in 2 strokes, we have used "Blue Marble" fossil based for 20 years in our Rotax engines. Chemical scientist that I bought a used sled from told me had researched oils for years and Blue Marble was his choice. Blue Marble claims smoother operation, cleaner engines and better fuel economy and I found all of that to be true. I will say we are running older sleds and engines and I cannot speak for the modern stuff but (knock on wood) we have never had an engine go down or show any signs of wear.
