This is a newly manufactured OEM style CDI box, made to replace a stock unit in late model Kawasaki H1  motorcycles. Internally, it is a modern copy of an original unit, with a similar electrical circuit, and components equivalent or superior to the originals.  The main capacitor is rated 2.2 uF, which is the same as originally installed, and the correct rating for this ignition system.  The main electronic component, the Thyrister (SCR), is rated at 8 Amps, much more rubust than the original 3 Amp device.  The diodes in the rectifier section are rated to withstand twice the current and more than double the voltage the originals could handle.  The housing is hand fabricated from heavy gage 304 stainless steel, beautifully finished with a brushed appearance, and designed to fit perfectly in the original mounting plate. The circuit is sealed in high quality epoxy potting compound for protection from moisture and vibration.

This CDI unit must be used with a filter ("B") unit.  It can be either a Kawasaki original "B" unit, or one of our new "B" units.  This CDI unit works like an original unit in every way, including the advance curve.  It produces fat, bright blue sparks at modest kicking speeds, like the original CDI unit did when new.  
We will repair or replace this unit, or refund the purchase price (at our option), if it fails to perform properly as a result of defects in materials or workmanship, within five years of the date of purchase.
Please Note that the wire lengths are different for the 1974/1975 H1E/F versus the 1976 KH500.  The table below shows the standard wire lengths for those models.  Please tell us if this unit is for an H1E/H1F, or a KH500.

H1E, H1F KH500
black&white, orange,brown 10" 6"

Also please note that we don't have the original style molded rubber 2-pin connector that mates with the alternator's connector.  We will attach separate bullet connectors that properly mate with the alternator connector without modification.
