Motor that came with the bike. Motor needs a refresh, but lots of high dollar parts. Looking for $1,500 complete, or offers on individual parts. According to the builder and previous owner, following parts are in the motor: HRC inlet springs WEB cams Ported and polished head Carillo rods High compression pistons (I beleive JE makes them for NPS) lightened crank balanced rotating assembly shortened velocity stacks epoxy filled valve cover (no need for black off plates) stock clutch I'm not sure if there has been anything done to the cases or not. NPS charged $6,500 6 years ago for all of the above. I don't know how many miles are on the motor, but judging by the dyno run, it is tired and needs a refresh. I don't really want to split the cases if someone is going to take this thing whole.
