This 440 has been converted to a 800 BB with race porting, SLP compression head, SLP race porting, big bearing update, Boyseen reeds, SLP push and pull snubbers, twin PSI pipes, and a 136"X2" track. The motor itself has about 500 miles at best too. I have had this sled out just a couple of time and found out pretty quickly that it's too much sled for the type of riding we do out here in AZ. This thing at 8000ft carries the skis at will just about anytime you ask it. This sled would be wicked stupid somewhere like either open mountain riding or trail riding. Boondocking thru tight trees this sled isn't for..LOL The sled is located in Flagstaff, AZ $2300
