Please Note: Parts listed here are for the 40PHH and 44PHH Mikuni Performance Carburetors. These Mikuni carburetors are also referred to as Type-R. There are differences between the Mikuni Performance Carburetors and Mikuni / Solex Original Equipment Carburetors (Type 4 40PHH, Type T, Type Q, Type 2, Type 3, Type 5). Many items do fit both applications, but not all. Some 40PHH Solex carburetors use 44PHH Mikuni Performance parts. Please be sure to compare images and specifications when available. If you are not sure if your which Mikuni Carburetor version you have, please compare your carburetor Float Chamber Cover (FCC) with the Float Chamber Cover Gaskets (Item#18).
