Spacer ignition -BGM PRO- PX, Cosa - PK/HP4 flywheel - 2.0mm 51305

Spacer plate for the HP4 ignition on Vespa PX, T5 and Cosa engines.

If the tolerances of the engine case, crankshaft, ignition base plate and fan wheel add up unfavorably, it can come to a fluttering ignition timing. The reason for this is that the pick-ups in the fan wheel are not aligned with the pickup. To compensate this difference, we offer you this packing plate.
