Oil filling up airbox - Eiger 400
 

Suzuki 2007 Eiger Quad Runner 400
The airbox is filling up with oil and then it smokes like crazy and fouls the plug.
All I can think of is excessive blow by. But this happened suddenly.
Thanks for any help.

Only 250 miles
 

BTW, It only has 250 miles on it.

did you chk the hose from engine to air box? is inside of hose oily? did you flip it or store standing on tail?

Is the oil red? If it is, then drain it. It is coming from air filter. (Did you just clean and reoil the airfilter?) I do not see that much blow by to get oil all the way back into air box before you foul the plug first.

do you have too much in tranny?
