Timing Disc Sip

Ignition timing degree measuring disc is a practical tool that should not be missing in any properly equipped workshop. The very precise SIP Ignition degree disc enables an optimal set up of your ignition system. It is compatible for use with all two/four-stroke motors including all models of Vespa and Lambretta and also 50-180cc two/four-stroke automatic scooter motors. Ignition set up tips can be found on the disc itself by a bit.ly code.

Basic ignition set up instructions :

• Determine Top Dead Centre (TDC) position

• Mark the position of the arrow on the fly wheel on the crankcase with a marker pen.

• Attach the degree disc and align the 0° with the marking on the crankcase.

• Mark also the desired ignition point (anticlockwise) on the crankcase.

• Remove the degree disc, start the scooter and with the help of the stroboscopic lamp, check the desired ignition marking lines up with the arrow on the flywheel. If not readjust the position of the stator plate until the correct position is found. To save time and effort during later servicing, permanently mark both the crankcase and stator plate to record their position in relation to each other.
