July 2017 - Just in, more of the magneto caps with manual advance and retard lever, for Joe Hunt magnetos! Easier starting for Joe Hunt equipped bikes. Two versions stocked by us to handle both rotations.

The Magneto Onboard Retard kit is a revolutionary device which aids starting by retarding the timing on fixed-position magnetos, helping to turn the infamous kick-backs and spit-backs into starts. When the cap-mounted lever is flipped, the points "shift" 10 degrees, retarding your timing 20 degrees for starting. The lever is then locked in the advanced position by a rare-earth magnet.

The complete kit consists of a new clear Lexan cap, cork cap gasket, a set of points, condenser, and the actuating pieces themselves.

C630 Nickel Aluminum Bronze is an extruded aluminum bronze that contains nickel, and is alloyed for exceptional strength and toughness. It’s used where higher mechanical properties are required. It’s used in equipment for the energy markets, in aircraft, marine and a host of other industrial applications.
