This Mikuni HS40 Easy Kit suits all Harley Davidson Shovelhead and Ironhead 1000cc XL Sportsters.
The kit includes a Mikuni HSR40 40mm Carburetor with choke cable, a specially designed Mikuni 1/2″ drop down manifold for better tank clearance, heavy duty manifold to carb rubber mounting flange, choke cable securing bracket, some jets for tuning, a throttle cable set to suit stock or +2′ applications, plus an air-cleaner adapter for mounting any custom air-cleaner that fits a Harley Davidson Keihin CV or a S&S shorty air-cleaner. The Mikuni HSR air cleaner adapter fits over an anodized alloy sleeve which is pressed onto the carburetor intake spigot enlarging it from 55mm to the 65mm outside diameter of the HSR.
Mikunioz has re-released the HS40 kit due to customer demand from Harley Davidson owners who back in the day ran these great carburetors and today whilst still riding these older bikes, want that Mikuni performance increase, smooth power and enhanced riding experience whilst not wanting to give all the engine components the work out delivered by the HSR42. Impressive performance increases can be expected when replacing other 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 inner adapter accepts the supplied OEM Mikuni Evo/ Twin cam adapter which requires the filter to have a positive mount back to the rocker boxes to securely hold the filter in place onto the carburetor spigot.
