Hmmmm .... I just pulled the #1 plug out of my '02 (feeling guilty about the original plugs at 30,000 miles) and not only does it not need replacement, it's also a very light tan color on the center insulator, either meaning it's not very very very very very rich or current fuels hide very very very very very rich very very very very very well!
I apologize to the other folks on the board, but someone has to say it:
Give it a freakin' rest Rob!
Every other post you seem compelled to write about how darn much you know and then argue about peoples actual experience. It must be nice to own the most perfect 919 on the planet and be intimately familiar with every mechanical and electrical system ever constructed.
We've all got access to wikipedia and google too.
It's insulting, unnecessary, and intimidating to people that have valid questions or concerns about their own bikes and experiences. I personally find it offensive and unwelcome.
Please channel this infinite wisdom into curing cancer, ending poverty and hunger, and bringing everlasting peace to mankind. It's simply not fair to the rest of humanity to waste it here. This is especially true since we other forum participants are so utterly and completely ignorant in regards to the topics discussed. Obviously quite a few of us suffer from Munchausen syndrome. I often remove my beautifully tan plugs and rub charcoal all over the electrodes and insulator so I can be part of the "in crowd" and pretend my bike runs rich too.
