HI, I have a complete Duncan 403 motor that I have dismanteld, it is going to need the crank rebuilt and a hone/bore job. what do you guys think I should do, sell it whole or part it, cases, tranny, jugs, coolhead, carbs, etc?
Under the intake on the juggs duncan ingraves the person who they did work for and the date it was done. might need a little mirror to see it. then just give duncan a call or email. Or atv world if you are out of the states. it is most likely there 350 national port job.
I have pics. nice set of paul turner hi rev pipes with duncan re packing tool an extra re pack, packing in silencers only have 30 minutes on them. 399.00
I have nice set of 35mm pwk carbs with Duncan racing bore and super flow mod,I think this mod makes them 36.9mm, and duncan extra jet kit, and cable. have pics pm me. make offer.
