Twin spark bevel heads . what do you know? about timing,plug heat range,rejeting,etc.

Re: Dual spark plugs
My Darmah was done when I got it.Uses a 10mm plug snuck in under the bevel shaft same heat number NGK8 ish I think. Timing retarded slightly 2-3 deg. or so. Really no difference other than looking cool. May have an advantage at crankshaft ruining speeds but on the street I think a good set of coils and a fat battery is all that's needed.
