1957-1966 XL/XLH Primary Cover
The first primary cover for Sportsters. Cast aluminum with the “Sportster” script cast into it.
It was replaced in 1967 when the electric start was added to the H model.
It is similar to the K-Model (also KH and KHK) primary which preceded it, with two notable differences.
The K-Model primary didn't have the scrips and the Sportster primary protrudes out further accommodating the compensating spring on the motor sprocket. 1)
