Guys, I just bought a compression tester today. I just wanted one.
My bike is running perfectly. New cylinder, new piston, and new rings. Broken in for 5 hours.
My maximum cylinder pressure is 160 lbs. It will hold this pressure for hours.
My question is this. How high can I raise this pressure, by head milling, before I get into trouble?
On a 68 mm bore, how much should the head be milled to raise the pressure to 185 or so?
Is there a better way to figure this?
Should I just say screw it and mill .5 mm from the head????
I would love to hear any opinion on this.
My altitude is 4600ft. I understand the pressures are lower here due to high altitude. How much can I mill to bring me back to seal level values?
