Ignition adjustment Vespa

In this SIP Technik blog, we’ll show you how to SIP Performance Ignition . We’re using the SIP PERFORMANCE Ignition system because, amongst many other advantages, it’s very easy to adjust without any flash-overs. In a future blog post, we’ll explain the procedure for an original Ignition system.

The powerful and reliable SIP PERFORMANCE Ignition system is available for almost all Vespa and Lambretta models.

Tools we use to adjust the Ignition precisely:

• SIP Ignition Timing Degree Disc
• SIP digital timing indicator
• Piston Stopper
• Index Set for Ignition Timing Degree Disc
• SIP Clamp Lever for Ignition Timing Degree Disc

Steps for adjusting the Vespa’s Ignition:

• Insert the Piston Stopper into the spark plug thread
• Turn clockwise until the Piston meets the stopper
• Reset the Ignition Timing Degree Disc to zero degrees
• Turn in the opposite direction until the Piston hits the stop (the value should be approximately 300 degrees)
• Enter this value into the TDC (Top Dead Centre) calculation Top Dead Centre (TDC) = ((360-x)/2) + x
• Remove the stopper and turn the Washer to the calculated Top Dead Centre (TDC) value
• Add the desired ignition timing. Normally 17–19° Desired ignition timing, e.g. 19° = Top Dead Centre (TDC) value + 19
• Turn the flywheel using the Ignition Timing Degree Disc until the desired ignition timing value is reached.
• Turn the Stator Plate until the mark aligns with the mark on the Flywheel.
• Screw the Stator Plate tight. Done.

With the SIP Performance ignition system, the exact alignment of the markings on both the Flywheel (rotor) and the Stator Plate (Stator) means that spark testing is no longer necessary. For original ignition systems, we recommend spark testing as a safety precaution.
