I have a complete union bay 900 based off a polaris 800 bottom. The bottom was checked for tolerances and a big bearing kit was installed at last rebuild for insurance purposes only. It has a fresh top end, new pistons and rings. The motor comes complete with bored tm 42mm mikuni carbs, cdi and chromed twin pipes cut and fit to an IQ racer with a headlight. It has a motor plate from power addictions fit to the racer with 5 motor mount locations and 1 extra ultra mount on the pto side plus a pto torque arm. 2 sets of heads and vf3 reeds. Upgrading to a 1200wc. PM me your email address and I can send pics. $3800

Feel free to contact me with questions

The union bay billet topend is 2yrs old, cases and crank are stamped 02 but were checked for tolerances and a big bearing kit installed this year with the topend rebuild. Standard ubr hp, I never had it on a dyno but according to curt it is a reliable 185-200 hp motor depending on the fuel run. The pipes were originally made for the ubr 900 from slp. I bought the stampings from mark and then had doug flannery cut and fit them into the chassis to allow the headlight. Stinger diameter is 31.75mm but I had a set of 35mm stingers welded on recently for my alt. I still have the original stingers. The pipes are similar to the 800 race pipes but made for the 900.
