My apologies and thank you for your continued help. I am used to working on dirt bikes where the specs are very strict. I would have thought 4 times the gap would be way too large. I checked the bore, as you described, and the taper does close in as one goes down the bore. However, I did not note the numbers. I will take pen and paper to it and get some readings. What is an acceptable cylinder taper? What is the maximum allowable end gap?
