300/440/550 650sx exhaust in cooling line?

[ags0702]

Should there be any exhaust coming out of my pisser line on my 650?
Recently it has been fouling out a cylinder everytime I take it out and ride, on and off.

My friend said there shouldnt be any exhaust coming out the cooling line and that this is a symptom of a malfuntioning head gasket. Can anyone give me any advice?

It sure does run good sometimes though, and then it will foul up the rear plug and only run on the front cylinder...Def. head gasket? Still reads 175 psi in both cylinders.

change the head gasket, takes a second and then test er' out

I'm running a kerker exhaust and I have part of my pisser running to the stinger and I get some exhaust coming out when I first start it, before water has a chance to get out. Never had problems with fouling plugs though...

see I get a lot of exhaust in the line after I shut it off in the water.

Change the head gasket like we've been advising. You can run into more problems if you don't.....
