Thanks to a rpm orientated variable ignition point, CDI ignition systems from PARMAKIT and VESPATRONIC etc. create improved torque at the lower end and a cooler combustion at the high end of the rev-range.
The GPX-PVL ignition system, produced by BSG, presents you with the possibility of optimising the ignition mapping of these variable CDI units even further. The GPX-PVL module can be programmed, with the help of the already include 'Lekor' software, to adjust the ignition point in steps of just 100 rpm with a 0.2° accuracy (e.g. 8000 rpm @ 16° -> 8100 rpm @ 15.8°). It also allows two separate mappings to be saved simultaneously which can be selected by the rider, even while riding. Due to fact that this ignition unit runs on 12V AC, neither an AC/DC converter or a battery are required. A version is also available suitable for combination with the BSG HPC crankshaft (#50500000)
Caution: Be careful to locate this unit somewhere on your scooter where vibration and temperatures are not too extreme, such as in the vicinity of the voltage regulator.
Conclusion: A well thought through upgrade for VESPATRONIC and Co. and perfectly suited for switching between different needs (e.g. town or motorway) or even race requirements.
SIP-TIP : Use a new ignition cable and spark plug cap (e.g. #85171000) with a 5kOhm resistance value.
