Harley Davidson Mikuni HSR48 Carb Kit & Jets, Rubber Mounting Flange

This kit is recommended for big bore and hi flow heads. If your bike is closer to stock use the HSR42/45

  The Mikuni HSR48 is slightly larger than either the HSR42 or the HSR45. It is taller and the spigot (engine side) is larger in diameter. This may result, with some installations,  in interference problems with chassis parts. While Mikuni does have a manifold assembly that fits the “48” to a stock Evo or Twin Cam motor, we do not make special manifolds for engines with non-standard cylinder head spacing or larger diameter intake ports.

48-2 Mikuni HSR 48mm Kit for Harley Davidson large capacity engines (Natural Finish Carb, Jets & Rubber Mounting Flange with slotted mounting holes to suit manifolds with 70 thru 77mm stud centre spacings)

Recommended for engines 115CUI and larger or if your heads have been flowed to require a 270CFM flow rate.
