The ZX unit, fitted to this model bike gives the following advantages:

1) Standard fitting in place of the complicated stock units... small size. Neat installation using original wiring harness.
2) Brings the complete ignition system up to modern standards, no longer requiring to use the original unreliable, expensive or hard to replace parts.
3) Converts the system to the early H1 style "battery powered mode."
This eliminates the need for the Hi/Lo Spd high voltage coils which can then to be used in a future system to run either High Intensity Discharge or Quartz Halogen lighting with NO FURTHER increases in battery/charging circuit battery consumption.  Additional power consumption here is 12 watts maximum.

For road racing and drag racing applications.
1) The new CDI will run as a simple minimal equipment, stand alone system.
2) Is compatible with external RPM limiting Tachometers
3) Will run 1.5 hours on a small set of AA nicads or similar... total loss system for weight reduction.
4) Small and light weight.
5) Potentially allows the rotor, and ALL rotating mass to be completely or partially removed from the crankshaft.

-----------STARFIRE ZX CDI INSTALLATION INSTRUCTIONS FOR H2------------

------------- STANDARD CONFIGURATION using the alternator CDI coils.---------------

1) Mount the CDI unit to the bike

2) Identify the three ignition coil primary wires, these are all red.

3) Connect the CDI ORANGE , BLUE and DARK GREEN wires to coils, these
are LEFT, CENTER, and RIGHT.

4) Identify the three pulse coil connections in the harness. These are
all WHITE

5) Connect  the three CDI wires YELLOW, PURPLE and LIGHT GREEN. These
are pickup coil LEFT, CENTER, and RIGHT

6) Connect one BLACK wire from the CDI to a firm ground.

7) Connect the CDI BROWN wire to a source of SWITCHED 12 volts provided
by the ignition key (any Brown wire).

8) Connect the GREY wire from the CDI to the WHITE/BLACK (ignition/kill switch)
single bullet connector.

9) Cut short the unused wires from the CDI and dab the exposed ends with
a spot of nail varnish. These are BLACK x 1.

The bike will now run.

The ignition system  is not using any magneto CDI coils, the current instead
being supplied in early H1 CDI fashion by the battery.  The additional average  
current drain on the circuit  is roughly equivalent to 2 or 3 small dial lamps
and will not be a problem.

---------MINIMAL CONFIGURATION for dragracing/ roadracing applications.--------


For minimal equipment dragracing/road racing use, The Starfire CDI will
function as a complete stand alone unit. It is suggested a small battery
pack be used to supply the required voltage. A pack of 8 2000 mAh AA
rechargable NiMh or NiCads will run the unit for approximately 1.5
hours. The GREY inhibit wire will cut the engine immediately when
grounded, and will  allow an external RPM limiter to be easily connected
to the system.

Wire the CDI as follows:

1) Mount the CDI to bike.

2) Identify the three NEGATIVE primary terminals on the ignition coils,
and connect all three to a firm ground

4) Connect the three wires from the CDI unit... ORANGE, BLUE, and DARK
GREEN to the POSITIVE primary terminals of the three ignition coils.
These are RIGHT, CENTER, LEFT

5) Connect the three wires from the CDI YELLOW, PURPLE, and LIGHT GREEN
to the three pulse coils (trigger coils). These are RIGHT, CENTER, and
LEFT.

6) Connect one BLACK wire from the CDI to a firm ground.

7) Connect the BROWN wire from the CDI, to one terminal of a kill
switch, or deadmans. The other switch terminal then connects to the
POSITIVE of the battery pack, the NEGATIVE of this pack connecting to
ground. A suitable POLARIZED plug will be required to assist changing
packs between races.

8) Cut short all unused wires from the CDI unit... BLACK X 4, GREY X 1.
Dab a coating of Nail Varnish  on the exposed ends.
