I posted earlier about the quad not reving, etc. So I had it bored and milled the head. Runs great now but it is blowing crankcase oil out the exhaust. It is litterally dripping on the chain guard when I shut it off. Is there a gasket or seal that can go bad? Does it take splitting the cases to replace it? Thanks.

 

2 strokes don't have crankcase oil. Most all will drip a lil oil out.
Some 2 stroke oils burn better than others. Maybe try a different brand.

 

Crankcase oil, clutch oil, what ever you want to call it. Basically it is pulling the oil from the clutch area.

 

I presumed it was unburnt 2 stroke oil comming from the exhaust.

I looked at the fiche, it does not show a gasket. You do have to split the cases if indeed that is what's leaking.

 

No, its more than unburnt oil. I guess I'll tear in to it this weekend or may take it somewhere. I'm getting tired of messing with it since I've bought it. Pretty sad that a 50 is kicking my butt when I've built countless big bike motors over the years.
