Stepped 3° Advanced Woodruff Key for Aprilia / Piaggio 50cc 2T Models.

The woodruff key locates the flywheel to its position on the crank, which sets the ignition timing of the electrical system (the point in the stroke at which the spark plug fires).

An advanced woodruff key advances the timing of the ignition system very slightly, which can produce more power, and operate more efficiently by burning more of the fuel in the cylinder (where some is usually wasted out the exhaust).

Upgraded performance CDI’s such as the Malossi TC unit also do this to a lesser degree, via an advancing of the timing at the CDI. Many newer model scooters such as the Euro 4 Piaggio Typhoon utilize advanced timing in order to adhere to strict emissions controls.

Advanced timing will produce more heat, so keep an eye on your plug burn to make sure you’re not running too hot.
