in general- the widest gap possible is better...but too wide and it'll not fire...
and our modern ignition systems look for a certain amount of resistance in the plugs and wires, otherwise the computer may think that a misfire is occurring and retard the timing...
resulting in reduced power and MPG.
or start throwing codes
highly tuned race motors and street motors are different animals
our street bike ignition systems are really really good, light years ahead of just 20 years ago.
unless you have specific needs and a way to measure results, you may do best to leave it

A "rounded" center electrode is one of the descriptions of a worn spark plug. While the manufacturers may be trying to sell more spark plugs, they continue their explanation by saying that crisp edges on both the center and side electrodes promote an easier, better spark and that worn, round surfaces require more voltage to fire. Many people believe they feel the engine running better with new spark plugs. Aside from some accumulation of combustion deposits, the only real difference between new and well used plugs is the erosion which has happened to both electrodes thus rounding them and widening the gap. If you wish to "pre-wear" your plugs before installing them, it is your call.
