With hand controlled advance, like OEM. This is a proven, tried and tested ignition module. Hall sensor type. Works with 6 and 12 Volt system and will never need re-adjustment or other maintenance. Shorter opening duration increases spark intensity by 60%. Fits to stock base plate.

Note: Will not work on 1964 Panhead models equipped with the stock dual points single fire system.

Note: See 519444 for the same module with electronic automatic advance.
