PRODUCT FEATURES
Self generating (no battery required) high performance cdi ignition system for twin cylinder 4 stroke with a 180 degree crank.
Low inertia rotor improves engine pick-up.
Independent digital CDI & HT coils for each cylinder are programmed with an optimum advance curve for the Honda 2 cylinder, 4 stroke engine.
Maximum advance of this system is 35 degrees, so static timing is typically set at 10 degrees to give a total recommended advance of 45 degrees. This is achieved by setting the timing as shown below.

Fitting Instructions
Loctite or similar is recommended to prevent screws/nuts from loosening. - Remove RH alternator cover and original alternator and rotor, an extractor will be required to take off the rotor.
- Fit the stator mounting plate with stator on to the engine. Use the three M6x20 screws provided.
- Fit the new rotor see fig 1. Fit the spacer provided on the end of the crankshaft, replace bolt, don’t fully tighten yet.
| Setting the ignition timing - Locate the stator using the two M6x16 screws with washers.
- See fig 2: With the RH piston set to 10 degrees BTDC rotate the rotor so that it aligns with the red mark on the stator (this is the position for the start of ignition).
- Fully tighten the rotor bolt, fine adjustments can be made by moving the stator.
- Tighten the 2 stator locking screws.
- Fit the two digital CDI’s and HT coils in a suitable position, attach the two sealed connector plugs to the CDI’s from the stator.
- Connect the orange leads from the CDI’s to the HT coils, the M6 ring terminals with black leads are connected to the metal body of the HT coils. Screw on HT caps, it is important that you use the 5k ohms resistor plug caps supplied, this is to prevent damage to the digital CDI’s.
- The black/white cable from the CDI can both be connected to an engine stop switch. When the black/white cables are connected to earth the ignition will be killed. Fitting is now complete.
