It's new, went with polini cp carbs for all of my bikes so I don't really need it. Definitely high quality and would probably rip on the right setup. Includes a rubber coupler but no hose clamps. 95$ shipped.
I also have a box of polini needles (10 pack) and slow jets 40-52 that I'll throw in. The mains fit in a cp so I dont have any to give up.
