Primary Housing Sportster

Primary covers for K and Sportster models

On the "small" Twins from 1952 onwards, the primary housing is part of the left-hand half of the engine housing. This minimizes possible distortion, simplifies assembly and, with the appropriate gaskets, is a compact and clean device. There are two covers in the outer part for easy checking and adjustment of the clutch and primary chain tension. Simple, quick and good.
