How does a CDI ignition system work on a bike?

The keyway on the magnet is offset to the poles of the magnet. Maybe putting it on backwards cause the sparkplug to spark somewhere other than close to top dead center of the piston. I pulled the magnet off, turned it around and put it back on. EUREKA! Bike fired right up and runs like a dream.

What to do if your CDI ignition is trouble shooting?

Trouble shooting hints. Caution ,if testing for spark ALLWAYS have a plug connected with the shell grounded,never ever test with an open plug lead, you may destroy the ignition coil. 1) Disconnect leads going to kill switch (shorting mode hookup!) and try starting engine (Figure out how to stop it in case it runs).

What do you need to know about CDI circuit?

Circuit Description Now let’s learn the CDI circuit operations in detail with the following points: Basically as the name suggest, ignition system in vehicles refers to the process in which the fuel mixture is ignited for initiating the engine and the drive mechanisms.

How does the spark timing on a CDI work?

The spark timing is controlled by a small trigger coil located in close proximity to the flywheel which generates a low voltage pulse (actually two, a positive and a negative one), as the fly wheel magnet passes by.

Where does the CDI box amplify the signal?

The box amplifies the small signal generated from the spinning magnet located in front of the pickup coil in the stator, just before top dead center (TDC), when your fuel-air mixture is ignited. The box can’t generate continuous sparks.
