This Mikuni HSR42 Easy Kit suits all Harley Davidson Shovelhead models.
The kit includes a customized Mikuni HSR 42mm Carburetor where for rockerbox oil line clearance we have re-manufactured this carb, lowering and moving the throttle cable connection to the left-hand side of the carb. There’s a choice of stock length or 6″ over throttle cables when ordering, a new OEM type throttle assy, a choke cable and universal bracket, an air filter adapter for the fitment of either any CV type filter or S&S shorty teardrop filter, a specially designed Mikuni 1/2″ drop down manifold for better tank clearance with heavy duty rubber mounting flange, plus some jets for fine tuning.
Earlier models using the O-ring seal type manifold will need to be upgraded for use with this manifold, to the later system with the purchase of a pair of band type seals and matching clamps. Later models will just need the purchase of new bands.
All filters must be solidly mounted back to the rocker boxes as this Evo/TC88 filter adapter only sits in place with an O-ring seal, relying on the brackets to pull it back and retain firmly in place. 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.For the fitment of some versions of the S&S Shorty air-cleaner to a Mikuni HSR carburetor, the breather on the backing plate may need to have some material removed with some others requiring material 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. See the picture showing this required modification.
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.
