Well dowop, i think you nailed it ! I checked the coils and the secondary on both is completly open. Unless theres something i'm missing,as per the haynes manual i checked resistance between the + terminal and the spark plug connection and tried all ohm settings and theres absolutly nothing. What i don't get, and someone please explain this to me, is how the bike ran as always (except for the sooty plugs and vibration) with no secondary. The wires read fine as does the primary. Problem is, i'll have to buy nology coils because the dealers i called will replace them under warranty, but i'd have to leave the bike for a week or 2 and i have no way to get back and then to the dealer to pick it up. And they won't let me just bring the coils in and give me a replacment. Not fun. Anyways, thats got to be the source of the vibration.
Why not have the dealer order the parts, set up a time to install them, then call you when they are ready to go? Shouldn't take 2 hours to swap the coils, much less 2 weeks!
The reason it still runs is that there is enough voltage generated to arc over the break in the winding. You aren't getting enough spark to light off the fuel properly because the secondary circuit is sparking at both ends.
