Nearly complete with my Mikuni 44PPH restoration but in search of the final piece. I believe these are the stock velocity stacks but I could be wrong, I have 5 that are in good shape and 1 that is completely destroyed.
Looking for 1 air horn to match the set (don't feel like spending $300+ on a whole new set just yet)
Basic dimensions are:
Carb matting side diameter: 48mm
Open air side diameter: ~78mm
Height: 50mm
If you have more than 1 available I would be interested in picking up extra as well.
