probably too much crank case pressure, do a leak down test on it, poor ring seal, oval cylinders or cracked pistons kinda hard to diagnose with out some more info, is there oil in your exhaust pipe? do you run race fuel? race fuel is known for sticking rings.

ya with straight c16 you stuck the rings for sure pour some oil down the plug holes roll the clutch over by hand it will tighten up as the rings expand, you will feel it get harder to roll over. i have the same problem if i let the sled sit with out running it. i run straight c 16

would a compresion test find out if a ring is stuck?

it cant hurt it anyway to get some oil there

i did the oil in the plug holes that might of solved the problem. sure would like to check any possible spots to check
