Is the wristpin diameter the same on your new cylinder as on the XR200? Is it the same as your China motor?

This motor is advertised with the same bore and stroke as a crf230. Which makes it a 223. (65.5 x 66.2 mm bore x stroke) Would need to measure to confirm.
This cylinder is sleeved at 69mm which should (math be right) make 247cc motor. I *thought* that this was a CB based unit and not a CG based???
