The CDI is a key piece in the management of its ignition advance which has an important influence on the performance of our two wheels.
The ignition of the spark plug at the right time can be controlled by a variable advance CDI which will, depending on the engine speed, decide to trigger the ignition more or less early compared to an initial setting: today one tests this variable advance CDI.

This CDI is delivered with a key. We will see in this video the complete assembly of this kit on a 2002 booster.
Although this CDI is sold for scooters with major modifications, this test will allow us to see if the investment is worth it even on a little modified configuration.
