Boss wanted to do a rebuild/ revamp on his 660, so here’s the cylinder Dealer took off, piston and ring, wrist pin, bearing and circ clips… cylinders in very nice condition inside with no chips or cracks, piston has some weird slight bur/ roll on the outside on one edge ( as seen in the pictures) “scoring/ transfer” on piston is very superficial and not feel-able/ can’t catch a nail on it at all. May need new rings but I didn’t put a caliper to them to see, asking $100 plus shipping. Text me if interested (518)-222-6394
