Chris...........we have a compression gauge system but thanks. Some have convinced me to NOT totally rely on that motor compression test due to valve timing manipulation. We are trying to simply check the cc's of the combustion chamber after we have verified bore and stroke are stock. We have the factory spec on the chamber cc's to most motors/years with only a few to go. This way the correct cc of 5W oil could be injected at TDC. We have to determine the exact level that factory spec considers. I am assuming with the plug in place but no one has verified that yet. I can test the theory on my stock ZX-10 and my stock R-1 to see where the pre-determined oil amount is meant to come out and go from there. Just looking for a fairly simple way to check compression other than with a gauge. We will have the plugs out and at TDC at some point anyway. I already have the accurate syringes, oversized needles and suction device to extract the oil when we are done. If the oil rises above a specific level or comes back out the spark plug hole....................."You got some splain'n to do Lucy!" I just was looking for someone to shoot holes in this idea so I can sleep a nights again and quit thinking about it.
