TECNIUM offers this CDI unit for YAMAHA YFM 250 BIG BEAR 2WD, YFM 250 BRUIN 2WD 2005-2009. The CDI unit is the brain of the ignition. On every revolution, a pickup next to the flywheel tells it where the engine is.
The benefits:
No spark although the plug, coil and stator are fine, misfires or cut-outs when hot, or an engine that will no longer rev out: the CDI unit needs replacing.
Cross-Mania tip: Before replacing the unit, check the plug, plug cap, coil, stator and earths; connect it with the ignition off and protect the connectors from water with dielectric grease.
