I hate starting threads but can't find anything on here.
After 2 years I am getting close to having my 86 200x moving. Yesterday i got the cam back in, head on and everything adjusted according to spec. This also includes the left crankcase cover/gasket and all bolts, as well as getting rid of that horrible cobra exhaust and fabbing up a pipe and mounting a "E" series muffler. It started fairly fairly easy. About 15 seconds into idle it started blowing oil out the left case cover (past the new gasket) just above the foot peg and below the countershaft sprocket. Soooo anyone have any idea what is causing this to occur? To my knowlege the gasket is not pinchedor broken. A few years ago, on my wife's DX the screen by the Drain plug was clogged by sludge which caused too much case pressure and forced oil into the the airbox. Well the "X" has no screen on the drain plug so what's causing this over pressure. Thanks, in advance!
