new plug wires - bike not running now

put on a set of accel 7mm wires, now the bike won't run at all. can see spark jumping on a test plug... is this a symptom of needing the stock plug caps?

Just wires, not coils and wires? Are the new wires inserted/screwed in far enough? Maybe enough connection to fire plug in atmosphere but not enough to fire in the hell of a combustion chamber.
