I am in the process of overhauling an fx 140 motor so I was wondering what grit of hone I am I going to need to hone the cylinders. I will be using oem rings. Reason for overhaul is water got in the cylinders rusted the motor tight but was able to get the old pistons out without damaging the bores so hoping a hone is all it is going to take this is the first step than I plan to measure the bore to make sure it is still within spec. I will be using new pistons.
