Has anyone tried measuring the charge pressure of their YS? I've had two different O-rings split on me just a little teensy weensy bit and boy you should see the fuel shoot out the side of the carb or the intake pipe!!!

Just because I'm weird it got me to thinking what kind of boost pressure they are making in that crankcase!? If I had the time I'd tap it and put a nipple in to gauge it and see....

I'm guessing more than 10 psi? Anyone?
