There are quite a few different estimations of CR floating around and I understand there are many variables in this estimation. I am slightly concerned about getting proper fuel for my bike to prevent engine damage since I reduced the squish band significantly. I started mixing 2 gallons of 116 race fuel to 4 gallons of 92 pump gas just to be safe since I have no good estimate of current CR. I have race gas readily available so this is no problem, and I like the way it smells. Would someone take an educated guess at my CR just for my peace of mind, please? Here are my engine specs: 67 mm BBR piston; 4mm stroked crank; some head porting by Terry Miller; .010 base gasket and .016 head gasket for a squish band of .038. Also, approximately how much did I raise CR by reducing squish from 0.085 to 0.038? This adjustment really made a noticeable difference in performance according to my butt dyno.
