Power consumption, E-ignition vs Points. also - spare advance cam?

<< < (5/5)

Laverda Dave:
On my original 400/4 I zip tied the box on the top frame tube and just clear of the carb bank as there was just enough room for it to sit between the fuel tank tunnel and the frame tube. I thought I'd had a result until one day when giving the bike a handful it topped out at 110mph🙄, (actually it was about 70!). The CDI box had slowly worked it's way back down the frame just enough to interfere with the top of the carbs at full throttle.
I'm 90% sure the Boyer does use a wasted spark Ash👍

Bryanj:
Boyer fire all the plugs all the time

K2-K6:
Thats my understanding too ... obviously two pickup though to give the 180 degree timing point.
