Points Interface Unit
The Starfire Point Interface Unit is required to use
the Starfire ZX Mark2 CDI unit with any bike using points (contact
breakers) for triggering. Priced
The unit incorporates three small LEDs, Red, Orange
and Green, to help with the easy setting of the initial timing. These
correspond to the RIGHT, CENTER and LEFT cylinders, and will be ON when the
points set for that cylinder is open, and off when closed. The points gap or
"dwell" is no longer important for correct ignition performance, allowing
the gap to be set very much closer to help prevent "flutter" at high RPMs.
These are adjusted by moving each contact set back or forwards to retard or
advance the static timing. This is normally done by measuring the distance
of the piston before top dead center, and moving the points position until
the corresponding LED comes on. The ignition must be on to do this.
units will be shipped with the CDI unit if requested. The original
condensers fitted to the points can be removed. Sparkplug gap may
need to be increased for improved CDI operation.
When doing any adjustments to the ignition, it is
important to always have the spark plugs connected to prevent ignition coil
