HSR42 Easy Kit


This Mikuni HSR42 Easy Kit suits all Harley Davidson Panhead and Knucklehead models when using a two bolt manifold.

The kit includes a Mikuni HSR42mm Carburetor with choke cable, a heavy duty manifold to carb rubber mounting flange, choke cable securing bracket, some jets for tuning, plus an air-cleaner adapter for mounting any Harley Davidson Keihin CV or S&S shorty air-cleane

Performance increases of up to 25% can be expected when replacing these two carbs with an even way more impressive gain if replacing an old butterfly type Harley Davidson Keihin or Bendix carburetor.

There is no form of air-cleaner mounting bracket system included in this kit as generally depending on what carb you are removing and or what type of air-cleaner you will be installing, you could expect to either use some or all of your existing brackets or otherwise require the fabrication of a complete custom made arrangement.

  The purchaser will be required to buy a pair of 89-95 OEM type Harley Davidson throttle cables unless replacing a Keihin CV or later model S&S shorty carb where the existing cables will fit. 

For fitment of S&S Shorty air-cleaners to a Mikuni HSR carb, some material will need to be ground off the outer edge of the S&S backing plate to allow for clearance giving total unimpeded movement of the return arm on the carburetor.
