These covers by S&S are as close to original as you can get without stealing one from a factory museum bike. Externally authentic to the smallest detail, including cast-in or stamped part numbers and date codes, yet improved with new technology inside.
The covers are cast from 356-T6 aluminum and CNC-machined for a precise fit. Additional material has been added around the kicker boss for strength. A single shaft bushing with end seal is used for improved oiling.
The "G-6" cover has a casting date plate and a stamped in part#, just as the factory did it from 1940-1947; the "J7" cover also has the date plate and a raised cast-on part number, the way it was done from 1948-1951. Of course, both covers fit all 1936-1984 Big Twins in custom applications.
