Mikuni Genuine Carburetor & Fuel Pump Rebuild Kits

Mikuni American continues to expand its line of Genuine Carburetor Rebuild kits and Genuine Fuel Pump Rebuild Kits. These kits are available for both Mikuni Aftermarket Products as well as Mikuni Original Equipment Manufacturers' (OEM) Carburetors and Fuel Pumps. All Rebuild Kits feature Genuine Mikuni Replacement Parts suggested for the rebuild, along with a Parts List and Exploded View Diagram to help with assembly.

As different vehicles required different jetting, Mikuni Carburetor Rebuild Kits DO NOT include jetting components.  
In older vehicles with a lot of wear, or those that have been stored with old gasoline, you may need to replace worn or clogged Needle Jets, Main Jets, Pilot Jets and Air Jets. You will need to order any required jetting components separately from the Mikuni Rebuild Kit. These jetting components are shown in the Mikuni Product Catalog on this website.

It is suggested to work with a qualified Mechanic to tune, rebuild or replace your Mikuni product. You can also contact one of the Mikuni Product Distributors listed on the website to assist and sell you replacement Mikuni Carburetors, Jetting and Parts.
