Description
Andrea Pinasco was one of the first mechanics who successfully tried to improve the performance of classic Vespa scooters, and his company Pinasco consequently became one of the household names for Vespa tuning. Carburetors, cylinders, exhausts, crankshafts - everything to make your vintage Vespa run better and faster.
This Pinasco Ignition 'Flytech' Vespa GTR / Sprint 125-150cc is an excellent alternative to the original part, for better throttle response and improved agility.The Flytech has a pre-set ignition curve. The flywheel introduces 2 performance-enhancing features: the magnets are protected by a reinforced steel ring, and placing the mass away from the axis means that the flywheel has greater rotational inertia without increasing weight, it weighs even less than the original. On top, the high-quality fanwheel (Nylon) with optimized fin design optimizes airflow, with 20% more air for efficient cooling. As you can see, Pinasco thought this through, and this state-of-the-art piece will definitely boost the efficiency and performance of your engine.
You can use a flywheel puller for original Piaggio.
Suitable for standard and sport setups.
Weight (flywheel): between 0.9kg and 1.4kg for small frame Vespa models, between 1.6kg and 1.8kg for large frame models.
1,600g.
Function of an alternator
The ignition or alternator consists of various elements that produce a spark at the spark plug, which ignites the mixture and thus makes the engine run.
Alternators are not always electronic. Vintage mopeds like the Peugeot 103 or the Mobylette have breaker ignitions, unfortunately they wear out quickly and become easily misaligned.
Nowadays, all vehicles have electronic ignitions, which are more reliable and durable.
The ignition consists of a rotor or pole wheel, a stator with the ignition coils, a wiring harness and a CDI. We won't go into too much technical details here, but the ignition, which is attached to the crankshaft, generates an AC voltage with the crankshaft rotating. This voltage is passed to a capacitor, which stores this energy to pass it on at the right time to the coil, which acts as a transformer to make the spark plug produce a spark.
Simply put, the ignition generates the electrical energy needed for the plug to produce a spark, which in turn causes the mixture to explode.
Ignition Performance
While most 50cc motorcycles and scooters are equipped with alternators that generate the power for the vehicle's lighting in addition to the energy for the spark, there are also racing ignitions like those found on motocross machines.
Performance can be improved very effectively via the ignition. By changing the ignition timing, you can optimize the engine's performance, but you should have the required know-how to do so.
The weight of the rotor can also affect engine performance. A lighter rotor will allow for a quicker increase in rpm, while a heavier rotor can help improve torque.
On 50cc motorcycles and scooters, you can change the ignition with a simple offset woodruff key, or you can buy for an internal rotor ignition. Most racing ignitions with an internal rotor also have a CDI with variable ignition timing, which maintains high torque at low rpm and maximum power at high rpm, as the explosion always occurs at the optimum time.
Removing and Installing an Alternator
To remove and reinstall the ignition, you will need special tools:
- For disassembly you need a flywheel puller to remove the magnetic rotor.
- When reinstalling the ignition you need a micrometer to adjust the ignition.
Here is a detailed tutorial to help you install an internal rotor ignition.
