907770 Steel inner primary cover, chromed

This chrome steel inner primary cover is designed specifically for 1970 to 1984 Big Twin kickstart models used in custom applications. It is a tin-style inner cover that should be paired with a 1955 to 1964 steel outer primary cover to achieve the correct fit and period-correct look. Mechanics should note that this setup is strictly for kickstart-only bikes and does not support electric start components. Additionally, if you are running a primary chain, the lubrication system will require modification to ensure proper oiling. It is a solid choice for builders looking to replicate early styling on later Shovelhead drivetrains while maintaining the durability of a chromed steel finish. This part replaces OEM 907770.
