This adapter kit allows you to mount a 37 or 39 mm carburetor on the standard 1600 cc manifold.
Our 37-PICT-3 and 39-PICT-3 carburetors are fitted with this as standard, to create a smooth connection between carburetor and manifold. If you've enlarged your own 34-PICT carburetor to 37 or 39 mm, this kit is the solution to avoid having to modify the inner diameter of the manifold, which is necessary to create the correct flow.
In addition to the adapter, the kit includes the correct diameter gaskets, replacement threaded ends and a number of nozzle sizes that will help you tune your carburetor optimally for maximum power.
The following jets are included:
main jets: : 127, 132, 137 and 140
idle jets: 50 and 60
