Breaker cam / cam ignition contacts Vespa Rally 200 Femsatronic up to VSE1T*0033996*

Suitable for Vespa Rally 200 with Femsatronic ignition up to chassis number VSE1T*0033996*.

The breaker cam is an important component of the Femsatronic ignition of the early Rally 200. It determines the geometry for triggering the ignition and must therefore fit properly and be technically flawless. As soon as the seat, groove or running surface are worn, the cam should be replaced.

Femsatronic Rally 200 up to VSE1T*0033996* Ø21 mm inside

What is important for the cam

Tight fit: the cam must not sit loosely on the cone or carrier
Intact groove: worn or damaged grooves lead to inaccurate ignition triggering
Clean running surface: damage or wear has a direct effect on the ignition function

Fitting instructions

On some models, the cam is not firmly mounted on the fan wheel, but sits directly on the crankshaft cone.
Installation position: the lettering on the component always points outwards, i.e. to the legible side.
Internal dimension: Ø21 mm

Important: Distance to the pickup unit

The distance between cam and pickup should be 0.25 mm to 0.30 mm on the Vespa Rally 200 with Femsatronic ignition. This value is important for a clean and reproducible function of the ignition.

Note on the feather key / half-moon key

The original feather key (colloquially known as a half-moon key) for the Rally 200 Femsatronic is no longer available.

The feather key is only used for fixing and positioning and does not transmit any force.
A half-moon wedge for the PX models, for example, can be adapted as a replacement.
In practice: file the height of the PX crescent down until it fits the Rally 200 application perfectly.

Conclusion

The breaker cam for the Rally 200 Femsatronic is a small but ignition-relevant component. If you ensure a tight fit, an intact groove and the correct distance to the pickup during the overhaul, you will create the basis for a cleanly functioning Femsatronic ignition.
