The Casatronic variable ignition kits from Casa Lambretta has a 2.7kg flywheel which is a one-piece construction to prevent magnets from breaking up. The ignition has built-in advance and retard, which will adjust the ignition timing closer to top dead centre as the revs increase, and retard the timing away from top dead centre as the revs decrease.
This gives stronger pull away at low revs and lets the motor rev more freely at the higher revs. Combined with a high power 12-volt output these make a great upgrade to any Lambretta. Please Note:- if used with a SIP speedo, change the settings on the speedo to twin spark mode.
