How much oil sledneck ?? ...... a few drops ?? ... a little ?? ... or a lot ?? ... must be some blowby from the compression getting down into the crankcase .... but I'm guessing .......... hopefully, someone with more internal knowledge will chim in soon .........
Might be a little dust on the Grizzly
But it only gets better, one piece at a time. 98 600 Green Grizzly. 27" ITP MudLites, EPI Clutch Kit, UNI filter, DynoJet kit - Stage 1, HMF exhaust .Murderfied cooling fan motor.
30 year old Simpson's Sears 46" Plow, crappy little winch. Fabricated harness . . .
just throwin' this out there, but you didn't happen to line up the ring grooves did ya?
something has to be causing pressure in the crankcase, and compression is about the only thing that'll do that. if it was a ventilation problem (oil gets hot, has to push the increased air pressure somewhere) then it wouldn't be coming out the vent, it would be pushing it past a seal. but since the oil is coming from the vent, the vent has to be clear. that only leaves blowby.
the ring end gaps aren't too big?
was the cylinder bored or at least honed?
did you use synthetic oil for break in? synthetic is NOT recommended for break in, because it works TOO well and will not let the rings seat.

Rings are all the way they are supposed to be. There is enough oil maybe 50ml. Thanks for the though on synthetic i overlooked that and used synthetic. Maybe they will seat goin riding tomorrow. And the carb and valves are all good no gas coming back through.Though i should mention it was deglazed and everything was measured in spec.
