2005 hyunsung comet 250 blowing oil and gas out of breather while running.

SOURCE: oil blow out the breather

An overfull oil tank will do it. Even if not overfull just about all harley's will blow oil out the air filter. Unless there is a bunch of oil coming out, it's not a problem What I've found is that the air filter eventually gets saturated and then starts to leak through. The level in the oil tank doesn't seem to matter. If you change the air filter the problem goes away, until the new one gets saturated and then it starts all over again. My plan is to get a K&N air filter, which you can clean yourself and save having to buy a new air filter every 4,000 miles or so.

This is a common problem on all sportsters, they have an oil blow by that dumps it into the air filter. I have found that if I run about a half quart low the problem goes away.

SOURCE: there's oil blowing out my enghine oil breather

This is common the solution is to run the oil half way between full and low.

hi
ther is a chance that being over filled will blow out of the crank breather so drain off to the correct level if then the bike still does this then you have to high crank presure meaning the bore and piston/rings are badly worn
thanks jay

The drain plug is at the bottom left corner of the center case. The oil filter is on the left case cover.
