Mikuni Carburetor

Fasten the Mikuni Carb to the Mikuni Intake Manifold.
Fasten the Intake to the engine. You can use some of the bolts previously removed.
1. Remove stock carburetor
2. Fasten Intake to Carb
3. Fasten Intake to Engine
4. Install Fuel Line
5. Install throttle Cable
Throttle Cable
Mikuni Carburetor
The Mikuni Carburetor does not use any of the engine's stock throttle linkage. Instead, the Throttle
Cable just slides into the carb and secures into place with a Wire Stop. Wire Stops can be crimped, brazed, or fastened with a small screw. Some throttle cables can be purchased with the wire stop in place, however, then you cannot cut your cable to fit the length you need. Crimping and Brazing require special tools. The easiest and least expensive is a simple Wire Stop available in the Throttle linkage Kit.
