This is a brand new aftermarket PeakRPM CDI box for the Kawasaki KEF 300 Lakota and the KLF 300 Bayou built between 1988 and 2005. It uses the original plug and play OEM connector design, with two plugs and five pins, so it drops straight onto the existing loom with no cutting or splicing. Dielectric connector grease is supplied with the unit.
The CDI box stores and releases the charge that fires the ignition coil, and it sets the timing curve the engine runs on. When it fails you generally see no spark at all, a spark that disappears once the machine warms through, a rev ceiling the engine will not pull past, or erratic running that comes and goes. This PeakRPM unit is built with OEM-grade electronic components and printed circuit boards for long-term reliability, and each one is triple tested at the factory before it is packed. RMSTATOR note that around 90 percent of ignition faults actually originate in a failed stator, so test the stator and the rest of the ignition circuit before condemning the box. They also strongly recommend replacing the voltage regulator at the same time, because a failing regulator is one of the main reasons these electronic boxes break down in the first place.

Frequently Asked Questions
Does this CDI box fit without modification?
Yes. It uses the OEM plug and play connector layout, two plugs carrying five pins in total, so it connects to the standard KEF 300 and KLF 300 loom exactly as the original box did. Nothing needs to be cut, soldered or re-pinned.
What is included?
The CDI box itself, plus dielectric connector grease for the plugs. Apply the grease to the connector faces on assembly - it keeps water and corrosion out of the pins, which is a common cause of intermittent ignition faults on these machines.
How do I know the old CDI box is the fault?
The usual signs are a total loss of spark, a spark that vanishes once the engine is hot, a hard rev limit the engine will not pull past, or running that cuts in and out for no obvious reason. Before you replace the box, test the stator: RMSTATOR report that roughly 90 percent of ignition complaints turn out to be a faulty stator rather than a faulty CDI.
Should I change anything else at the same time?
RMSTATOR strongly advise replacing the voltage regulator alongside the CDI box. A regulator that is letting voltage spikes through is one of the main reasons an electronic box fails, and fitting a new CDI to a circuit with a bad regulator can simply repeat the failure.
