True. The hardest part is finding a trustworthy shop. Ask around from your local Cruiser guys to see who they recommend in your area. Then, go and talk to the shop owner/machinist/assembler to determine their background with the F series engine. How many have the done in the past? Are they honest enough to rehone the cylinders and re-ring your stock pistons without pushing you to pay for a full bore and new pistons. I think the general consensus among the 'Mud crowd is the preference for a rehone and keep the stock pistons whenever possible, assuming no over-bore is necessary to clean the cylinders up. In reading other threads as well as talking to my machine shop, the OEM or replacement pistons are getting tough to come by.
