Im currently rebuilding my 2002 yz426f that had 300 hours on the stock piston with a new stock piston and ring kit and reusing the cylinder. I need to deglaze the cylinder, and i will be using a ball hone and there are multiple options for the balls hones from the type of abrasive to the grit of the abrasive. Does anyone have any idea what abrasive and what grit to get? I read on a GSXR forum that suzukis techs say a 240 grit Aluminum Oxide ball hone is best for deglazing a nikasil cylinder. Does that sound right?
