Complete 4-speed gearbox with close ratio and kickstart pedal

For all Big Twins, 4-speed, 1970-early 1984. Has a close-ratio 2.44:1 first gear, with a close-ratio 1.35:1 third gear, ideal for FX and FL models. The clutch sprockets and their corresponding dogs have been widened by .020" (0.5mm) to prevent breakage. The cases are cast "356" aluminium and their quality has been raised to T6 by heat treatment. These gearboxes have been machined to accept a pulley for belt secondary drive. A speedometer drive, 1:1 ratio, is included. The sprocket and clutch lever are not included; they must be ordered separately. A perfect choice if you are building a bike from scratch or if you have to replace a gearbox that has left you stranded too many times.
