37 PICT Big Bore Carburettor

Big Bore 37 PICT carburettor for 1600cc and larger Type 1 twin port engines

Excellent value for money and a straight bolt on big bore upgrade carburettor, perfect for a mildly tuned street engine just to get a bit more oomph and torque, without the expense and maintenance of a twin carb kit.

We would recommend these for 1600cc – 1776cc engines.
