Hello all.  I have a friend with an inturder we looked at it last night and it has no fire to the rear cyl.   I switched the coils and still no fire on rear cyl. ( by no fire I mean I have checked the spark and there is none ) I told him we may need to take the side cover off and see what gives it the signal to fire But I am not fimiliar with this type of bike.  Mine are all controled by the comperter grounding the coil, this one doesn't seem to be that way.
Any ideas as to what to check?  

I have a 2001 vs1400 that had the same problem. It was a bad plug, pulled it it looked fine grounded it and fired up the engine and no spark. Got new plugs and it works fine.
