This is the AC non battery performance version with variable timing.
The CDI module is the '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 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 centre (TDC).
One of the most major advances achieved is the production of the fly/fan wheel unit as a single component, avoiding a riveted inner mounting-cone and an uneven rotation. This greatly reduces engine vibration while also noticeably extending the working life of the flywheel side crankshaft bearing. The fan wheel is CNC machined from solid aluminium and delivers an identical volume of cooling air to the cylinder as the original throughout the whole rev-range. The amount delivered by most aftermarket ignition systems is easily surpassed by our design, without preventing higher motor speeds.
The flywheel intended for the DL/GPs weighs 1650 gr. and for the LI/LIS/SX/TV 1690 gr., making them both considerably lighter than their original counterparts. This primarily improves throttle-response, but leaves the motor easily manageable in urban traffic and while carrying a pillion. Our SIP – VAPE flywheels are 100% compatible with the original flywheel remover type.
