I have this Ducati CDI and this box and am getting a weak spark on a B7HS or cooler sparking plugs. The hotter sparking ones like B6HS and up seem to make slightly brighter spark but still weak. I used to get much brighter spark on same setup.
I've been meaning to get the Pietcard 2041 retarding CDI box and coil. Should I go for it to see if my problems go away?
