Janus 250 Nibbi PE28 carburetor to stock air box reducer coupler

about this

Changing out your stock PZ30 and upgrading to a Nibbi PE28 carburetor? If your are on the fence, I say go for it. The PE28 is actually larger than the stock PZ30 and it produces more power all around and it’s easier to tune. This reducer coupler makes it easy to connect the new carb to the stock air box. One end is 40mm I.D. and the other end is 50mm I.D.
