SIP Digital Gradimeter Support for SIP Adjustment for Vesp

Properly set ignition timing is essential to any tuned engine. This factor often separates the wheat from the chaff.

The SIP mounting bracket for the SIP Gradimeter is a very practical tool that should not be missing in a well-equipped workshop. In combination with the SIP Gradimeter it allows an optimal setting of the ignition point of the engines. It can be used on both two-stroke and four-stroke engines, no matter whether from a vintage Vespa or Lambretta, or from 50-180cc two-stroke and four-stroke automatic scooters.

Instructions:

1. Determine Top Dead Center (TDC)
2. Mark the position of the arrow on the flywheel on the crankcase with a marker.
3. Attach the degree disc and align the 0 with the marking on the crankcase.
4. Also mark the desired ignition point (counterclockwise) on the crankcase.
5. Remove the degree disc, start the scooter and with the help of the strobe light check the desired ignition marking lines with the arrow on the flywheel. Readjust the position of the stator plate until the correct position is found. To save time and effort during maintenance later, permanently mark both the crankcase and stator to record their position in relation to each other.
