SIP have managed to gain the assistance of a major European producer, VAPE, to manufacture these high-end ignition systems for our beloved Vespas. The materials, production and construction of the SIP PERFORMANCE ignition systems are of the highest quality. The laser-cut logo is a good indication of the overall clean and efficient manufacture of the components of this kit.
The electrical functions are representative of state of the art modern technology. Due to the eight coils included on the stator-plate enough power is created at tick-over revs to already fully illuminate the Vespas lighting. We have both AC and DC versions available and we recommend the DC type if you wish to power digital components such as the SIP Speedometer, or you require a high battery loading charge. The CDI module is available as a 'Road' version with a static ignition point, similar to the original item, or a 'Sport' version that includes a variable ignition point which advances at low revs. This increases the available torque - especially at the lower end - and the ignition point is then gradually retarded as the rpm rises into the power-band. This also helps reduce the combustion temperature while simultaneously providing an increased rev-range.
The pick-up on the stator-plate is split into two and arranged on top of another instead of next to each other as with the original design. This eliminates the possibility of false positioning during the initial set up due to the sloppy manufacturing tolerances included on many Vespa engine casings, crankshafts, stator-plates and flywheels. The exact ignition point is clearly marked with a precise line on both the flywheel and stator-plate, which allows ignition adjustment without stroboscopic lamp. All you need to do is find out the top dead center (TDC).
