This German Company makes amazing electronic ignition. Faced with fitting THREE sets of points and condensers in the same space as my SOHC Hondas use two, I gave it a try. A micro processor controls spark and advance curves (select from 7 options). But, it all hinges on setting the engine at TDC on #1 firing stroke, then setting the rotor to “communicate” that position. As the advancer has been removed, there is no longer a way to use a timing light and confirm idle and total advance. The visual marks disappear when the advancer is removed.
Fortunately, the Benelli SEI has a crank stub, sticking out the other side (the alternator is mounted above the clutch basket). The crank end is keyed (4mm) and threaded (24 X 1.5mm). Here’s a photo of the degree wheel hub I machined up to fit the crank. It’s keyed to the crank, now I need to find a nut to lock it down and make a fixed pointer plate. Once I physically mark TDC, I will be able to fire up the engine and confirm I have about 6 degrees of advance at idle and 32 degrees of total advance!
A lot of work, but the only way to confirm I got it right........
