MIKUNI HSR45 SMOOTHBORE CARBURETOR KIT

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 1984 thru 1999 Evolution Big-Twins with or without manifold and 1999 thru 2017 Twin-Cam models complete with manifold. For custom applications the carburetor is also available separately.

Note:
1993 to present models need ZPN232234 crankcase breather kit. 1984 thru 1989 models also need 1990 thru 1995 stock Big-Twin style throttle and idle cables.

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 models. Most cables are available in black vinyl or braided steel.
