Engine tech 900 big bore kit for sale for a 700 engine. This kit is damaged. One cylinder and piston is perfect and has never had an issue, could probably use a fresh set of rings although compression was fine. Other side piston is toast and cylinder was scuffed too. Tried honing it but its still scuffed a little on the left side of the exhaust port. Selling this cheap. Looking for $800 obo. Good chance to pick up a spair piston/cylinder for your kit or maybe fix the cylinder and get it running again. Includes 12:1 and 13:1 domes. Was a great engine too. Ridiculous power and very reliable as long as you dont push it too far. Probably has about 2000 miles on it.
