Electronic ignition Honda CB250

Electronic ignition for Honda CB250 including CB250G5. This device replaces the contact points and condenser with a contactless system triggered by a light beam. This device generally consists of three main components: 1. An adapter plate carrying the infrared light-beam units (one per cylinder), whose beams are interrupted by the rotor as it turns on the engine cam or crankshaft.

Additional information

• When the light beam is interrupted by a rotor blade, the electronic module fires the coil. (Some systems are fitted separately with one adaptor per infrared system, rather than all systems on a single adaptor)
• The adaptation kit also includes the parts needed to fit the lamps around the motorcycle's cam or crankshaft
• 2. A rotor that fits on the motorcycle's cam or crankshaft and interrupts the infrared beam to trigger the coil
• This rotor can be metal or heat- and solvent-resistant plastic
• 3. An electronic module that reads the rotor signal and fires the coil
• It can run on positive or negative earth depending on your motorcycle's set-up, with a separate switching channel for each infrared system
• The module is available in 6 and 12 V, so it suits older motorcycles
• It has an LED timing indicator
• 4. A wiring loom is supplied with each kit, matching the dimensions, connectors and wire colours of the motorcycle's original wiring for a quick, easy and professional installation
• The system needs only standard tools and is easy to install
• Please note that the primary resistance of the ignition coil must be at least 3 Ohms (many motorcycle coils are 4 Ohms or more)
• Please also note that the system has no ignition advance or retard function of its own and relies on the motorcycle's original mechanical advance and retard mechanism
