Compu-Fire electronic advance
ignition system

Compu-Fire has announced electronic advance ignition systems for 1970 to 1999 Big Twins and 1970 to 2003 Sportsters. This digital ignition uses advanced Hall-Cell triggering and surface-mount technology with convenient built-in “Accu-ray'” static timing LED. 

Features include 8 selectable advance curves for a variety of applications, and it can be used with either dual or single fire coils. It also has an rpm limiter and V.O.E.S. adjuster.
Compu-Fire reports the ignition uses extended temperature and low voltage operation that increases performance and reliability, and soft start circuitry allows easy starting under low battery conditions. 

Also seen here is Spyke’s petcock fuel valve, featuring a swivel outlet for universal positioning so one part number fits most OEM and aftermarket applications, including all Harley applications, except fuel injected models. The Spyke petcock is said to significantly outflow stock and modified configurations.

For 3” open belt drives Spyke has grind-free 3-piece jackshafts that are said to eliminate the banging and grinding associated with many 3” open belt drives. This jackshaft has ramped teeth and enough flex to integrate seamlessly with any 3 inch open belt drive.
