This sled is the end result of a long decade plus mission of what used to be a totally homemade 4 cyl 2 stroke 800, or 1000 depending on what cylinders were on it. That was built in the early 90s, In 2012 Olav Aaen and ourselves set to revamp the 4 cyl engine. Off to Olav it went, He built the pipes, ported the cylinders, bored new carbs, fitted it to our old chassis, I made the mistake of no putting a bearing on the crank in the middle of our homemade 4 cylinder, which was 2 engines welded together, 3 cranks to make one. This was done by Jerry Danbom and several of his friends long ago. I rode the sled once down the test track. It twisted our chassis. Thats when we set out to get the proline built. Then i snapped the crank on the new chassis. So it then became a 1000 3 cylinder. It has over 320 hp weighs 256 lbs. All carbon fiber hood. all billet aluminum chassis.
