The correct ignition timing is important for the thermal health of the engine:
Reliability
Durability and
full power output
Anyone tuning their Vespa, rebuilding the engine, or rebuilding it as part of a restoration should not rely on the existing markings on the engine housing, flywheel, and ignition base plate for ignition adjustment, but should measure it themselves and adjust the Vespa ignition correctly. The correct adjustment of the ignition on your Vespa engine is easily possible with these electronic timing lights for gasoline engines with contact or electronic ignition -> transistor ignition system (CDI ignition as standard in ET3, PK, PX, Cosa, T5 etc.). This of course also works with Lambretta ignitions. With these timing lights you can also adjust the Lambretta ignition. With these stroboscopic guns, both old 6-volt and modern 12-volt ignitions can be adjusted!
Comparison of stroboscopic timing lights for Vespa & Lambretta
3 versions: large, small, and with onboard or external battery
A super-bright xenon tube and a special collector lens ensure optimal visibility of the fixed marks with these timing lights: even at speeds over 8000 rpm in the near field. The gun is connected using an inductive clamp on the spark plug cable directly to the rubber insulation, without direct contact with the wire. Our timing lights are equipped with a rubber coating on the lens. This protector protects the plastic housing as well as the lens and ensures long-lasting enjoyment of the product.
No external power supply is needed. Two D batteries (mono, LR20, MN1300) are used for power supply, these are not included! But you can order them here right away. In addition to being used as a timing light, it can also be used as a work lamp!
This is the largest gun, which fits very well in the hand. The cable with the two alligator clips is a robust and practical coiled cable that is connected to the gun with a plug. Optimal gun for the ambitious mechanic and tuner - PROLITE version. Regardless of whether it is a 6V or 12V ignition, an external 12-volt power source (e.g. a car battery) is always required, unless the vehicle already has one.
For the occasional adjustment of the ignition, we have this lightweight and handy TRISCO-ProLite timing light in our program. It fits well in the hand and of course also has the rubber protector. The cables are permanently connected to the housing of the gun. Regardless of whether it is a 6V or 12V ignition, an external 12-volt power source (e.g. a car battery) is always required, unless the vehicle already has one.
These are for Vespa and Lambretta scooters: strobo or stroboscope - lamp, also called strobolamp colloquially among scooter riders, also abbreviated as TDC. Don't worry, you don't need a gun license for this gun, with this timing light you also check stroboscope gun / blitzer or flash gun and stroboflash the ignition timing on the scooter via flashes, flashlight from the timing gun. After adjusting the ignition, you can then strobe the ignition to check the ignition setting.
