Do the i.e. bikes only spark on the compression stroke then? I ask because I have a 916 which is obviously i.e. and uses the same type of pickup but I thought that both plugs sparked together every rev?...

Dukedesmo: at least they have the pickup on the belt drive gear which rotates half as fast as the crankshaft.

Guess I'll have to find out if the ignitech has a wasted spark when set to the ducati 48-2 pickup type.

Good point, but the reason I suspect the 916 has a wasted spark is that when setting up my digital dash, the rev counter has different settings for different cylinder configurations and it needed to be on the first (or last?) setting to give the correct RPM.

So unless the dash doesn't work on a single-cylinder bike then I assume that it is firing every time and that I'm actually on the single-cylinder setting?

900 i.e may be different to a 916? but it uses the same timing sensor (at least an ST2 does) also the Ignitech may allow different setup?

Interesting stuff though, especially as I am also in the process of building a 900 (944) with split carbs, Ignitech and other mods...
