Mikuni carburetor 42mm for Mud Buddy outboard motors with a single carb kit installed large block vanguard engine.

Mikuni's HSR42, carburetors are the finest VTWIN carburetors made today. They give superb throttle response and deliver all the airflow needed for any level of Mud Motor performance.

The simple addition of an HSR42, together with high flow air cleaner and exhaust modifications can increase power by 25%.

The carb dramatically improves the power of the Vanguard engine and delivers unmatched throttle response and acceleration! Maximum horsepower is typically increased from 33-35 to 40-44 HP. This example "before and after" power increase was produced with the combination of the Mikuni HSR42, a BPS Intake Manifold and a BPS "Q" Muffler.
