New electronic ignition for the Lambretta lui & Junior series from Vape!
Now New!
There are only two original ignitions for the Lambretta lui and Junior series: one for all models with 50 cc displacement 4-pin ignition system from Dansi and for the models with more displacement (lui 75 and J100-125) one 6-pin Ducati ignition.
The power output of both ignitions is very manageable: the Dansi ignition is included 6V / 18 watts and the Ducati version at least with it 6 V / 33 W .
The 50s models have - in a negative sense - absolutely minimal electrics, which usually don't even have a brake light. An upgrade is impossible due to the non-existent performance of this Lambretta alternator.
Comparison of the power output of the ignition systems
Ignition Ducati 6-pin J 100, J 125 6V / 33W
Ignition Ducati 6-pin lui 75 6V / 33W
Ignition Dansi 4-pin J 50, lui 50 6V / 18W
Ignition Vape lui 50-75, J 50-125 12 V / 110 W
vape 80 watts, consider 2.000 U / min
vape 110 watts, consider 6.000 U / min
This means that the new lui and Junior Vape ignition is a more than contemporary update 12V and 110 watts Perfomance. In addition, there is the unbeatable advantage of everyone electronic ignition: There are neither capacitors that burn out nor breakers that are subject to wear. Maintenance work and a weak ignition spark are a thing of the past.
Due to the very high ignition energy at low starting speeds, the vape ignition offers better starting behavior. The CDI is suitable for all original and tuned engines with a static ignition timing.
Thanks to the 12 magnets in the magnet wheel and the 9 coils on the ignition base plate, a high current output is available even at low speeds and the flickering of the light when idling is no longer present. The maximum output of the alternator is 110 watts.
This means that the models with 50 cc displacement can also be perfectly upgraded to the features of the larger models such as high and low beams and a brake light. Additional consumers (USB socket, exhaust gas temperature and the like) are of course no problem either.
The ignition magnet wheel is one-piece, manufactured to a high quality and balanced. The fan blades are CNC milled. The design of the fifteen fan blades has been optimized for higher cooling performance. The weight of the magnet wheel with fan blades is 1,2 kg.
Weight of the pole wheels in comparison
Flywheel Ducati 6-pole (Innocent number 00840134) J 100, J 125 1,35 kg
Polrad Ducati 6-pole (Innocenti number 00860038) lui 75 1,35 kg
Polrad Dansi 4-pole (Innocenti number 00860030) J 50, lui 50 1,4 kg
Polrad Vape with CNC milled fan blades lui 50-75, J 50-125 1,2 kg
Here we have put together the essential components - in addition to the ignition - for converting the on-board electrical system from J 50 to J 100 / J125:
A special feature of the J50 models is the limited space available with the original 50 rear light. A flat LED universal rear light can be the solution here.
When upgrading the lui 50 to lui 75 electrics it looks like this:
The lui 75 terminal board is - so far - only available for the original contact ignitions. When converting to electronic ignitions, all plug connections should be bridged together so that regulated 12 V is available across all of them.
Only green must not be combined with the other colors; here the engine is switched on and off.
