veetwo did plenty of dual spark setups as well..  when dyno'd it showed little difference in performance. So not really worth the cost.
I think ducati did it more for emmisions...

Funny thing is I think the new Evo motor is back to single spark.

Very true.
Maybe more compression and better combustion chamber design lets them get away with one plug.

Hard to have more than one plug on a 4 valver

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the airâ€"these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.
