Spark plug?

[Bill in OKC]

I have read some threads that suggest the iridium plugs need a larger gap even though the manufacturers say not to gap them.  Folks who had problems with the iridium plugs have set them to factory gaps and even larger say it makes them work better...  ??  Just have to be careful and not break off the electrode.

Here is that thread. http://www.ducatimonsterforum.org/index.php?topic=54367.0

Gaps from NGK
NGK 4339 DCPR8E      Gap: .028" (0.7mm)
NGK 6546 DCPR8EIX   Gap: .032" (0.8mm)

So they are gapped larger.

I have read this several times in several places.  .04 maybe?  I have not had any problems with the stock gap but after 5 years on the same set of plugs I might try something different with the next set.
