Some have, but the stock plug is more than adequate. A racing plug will do nothing but cost you more money.

I am using an irridium plug and its working great, started even without the choke cold... had never done that before!

An iridium plug will not overcome the requirement for extra fuel when cold. A new plug will fire off a bike that is jetted too rich though.

I put in a irridium plug last ride and starts are easier (09WR450), could just be a new plug though.
