I a have for sale a complete 2005 series 3 800 motor w/ a sea-doo clinic crank (200 miles) and a rk tek drop-in-kit (800cc) with billet head. Top end was built to be able to run from 2000' and up. It is 12-1 compression ratio. Top-end also has 200 miles on it. Has been a fun motor. I had it in a mxzx built in to a hillcross type sled, but crashed sled and don't need motor this year. This motor is great for someone you lives at lower elevation because you get the benefits of the drop in kit and dual ring pistons but with safe compression. I also have a set of twin pipes that would work great with this motor. Serious inquiries only please. Travis 5094331571
