I recently replaced my coils with the Dynatek 3 ohm mini coils and got a great performance gain.
Today I replaced my old standard leads with a set of Magnecors. I specified them with the red 90 degree spark plug boots to match the red race leads.
Magnecor had reservations on these boots clearing the cyliner head fins but they clear just fine.
As Magnecor claim there leads are not a performance tuning item, however I am guessing my old leads may have been arcing somewhere because the bike runs smoother and sharper with the new leads. Not as much gain as replacing the coils but definitely a worthwhile gain.
The bike is idling slightly higher and smoother ... and is more willing to rev out past 5000 rpm than it used to.
However while the coils and leads have made the bke smoother and crisper across the rev range it still runs a little lumpy between 3000 and 4000 rpm (particularly under load). It's very smooth up to 3000 rpm and also from 4000 rpm on.
I am guessing that the fuelling is not quite right through this rev range?
The mufflers have been cored and I am running without the snorkels in the airbox.
Is this lumpyness more likely to be a carb synch problem or rich/lean running from 3000 to 4000 rpm?
