MIKUNI HSR42 SMOOTHBORE CARBURETOR

MIKUNI HSR42 SMOOTHBORE CARBURETOR

Mikuni re-designed the popular HSR42 Performance carburetor and upgraded it with a 45mm venturi to accommodate for large cubic and High Performance Big Twin engines. The HSR45 carburetor has the same proven quality features as the HSR42 with only a larger venturi for a bigger airflow, which is needed for highly modified engines. It is absolutely the best carburetor available today if you don't want to have any restrictions in your incoming airflow for a maximum air-fuel mixture. Kit comes with carburetor, jet kit, K&N air filter, and chromed air cleaner cover. Works with stock style throttle cables as used on 1996 to present models. Available for Evolution Big Twin 1984-1999 with or without manifold and Twin Cam 1999-2017 complete with manifold. For custom applications the carburetor is also available separately.

Note:
Models 1993 to present need ZPN 232234 crankcase breather kit. Models 1984-1989 also need stock Big Twin style throttle and idle cables 1990-1995.

Throttle and idle cables for use with Mikuni HSR42, and HSR45 carburetors Early style HSR42 and HSR45 carburetors have the cable wheel on the left side of the carburetor and use cables as in the table below. Late style HSR42 and HSR45 carburetors have the cable wheel on the right side of the carburetor and use 1990 or later OEM style cables as used on Big Twin. Most cables are available in black vinyl or braided steel.
