for sale, 97 583, fresh top end, never melted down it was just due for a re-ring and i decieded to put new OEM pistons in while i was at it, 4500 miles on motor total, shaved 670 spec rave valves, milled head for higher compression, FAST twin pipes into Dyno port can, comes with complete carbs and pipes for the right price. this is a first pull motor, i have never had a problem with it since i bought it brand new but i personally need more power so i'm stepping up to a 740 big bore
