I'm glad I'm good company on this one. I don't mess with saving money on do-it-yourself rebuilds. Its risky business putting a new piston in a cylinder that is not replated. If a motor has low hours and no damage, you can surely put a piston in it, but only once like that. If there's damage of any kind, it is thru the plating. They clean up the cylinder and plating fills in tolerances back to stock size. Any boring or honing should be done by experienced engine builder with mic's. If you want to save money and do most of the work, dissassemble, take just cylinder to engine builder. Order your rebuild kit after varifying piston size, and reassemble yourself. Plating and micing are only a fraction of the costs and labors of the total rebuild. They like to get a mark-up on the rebuild kit, and rightfully so, if you are not confident enough to get the parts yourself. You will save money in the long run, delegating out some things not to mention the added peace of mind while ripping it up out in the wilds.....
