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?

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 have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.
