I'm trying to determine the static compression on my kz750 twin. I have all the figures i need except the compressed head gasket thickness. Everything i have found says "consult manufacturer" for these numbers. My plan right now is to throw in a gasket, compress it and then measure the thickness of the copper rings that are embedded in it. Is this a good way to get this number?
I don't know if that will work but another way is to put the head on and torque it up without the gasket. Measure from some point below the head to a point on the head. Then pull the head and install the gasket. Torque it up and measure again.
I ride Z1's. I have a couple of '75's, plus an '80 KZ1000LTD.
