Oddly enough these USA units look EXACTLY the same as the ones offered above for $5,800
I have NOS unfitted 44PHH Mikuni's and they didn't quite look the same. Sorry to say, but feel those are rebuilt, not new.
Look at the finish from sandblasting, the linkages, soft mounts, ram tubes etc.......
Even the banjo fittings don't look quite right.
That's possibly the factory setting and will be pretty close to what you would want. A good base tune.
I've had twin su's, hitatchi's ound tops, EFI 40PHH and 44PHH
I'd take the Mikuni 44PHH anyday!
