I just changed my spark plugs

I dunno, but if it makes you feel any better, mine looked like that too...

Great, I feel like I just had a massage.

 

[Gunnybusa]

Mine have looked alot like that every time I have changed them.

Check out this LINK for checking spark plugs.

I noticed the foam from my air intake was kinda deformed and I assumed that some moisture seeped in? Maybe I am worng? I think I only had one that looked like that.

Mine never look like that. They always look very slightly more worn than when I put 'em in.

--Wag--

All that moisture down there and looks a little rich...

 

[MrGixer]

As said above. Looks a bit rich.

All the rust is caused by water/moisture collecting in the wells where the sparkplugs are. Could try putting some high temp silicon grease on the rubber cap on top where it meets the rocker cover to prevent water getting down there in the first place maybe?

I would say maybe a little rich and moisture from rain or washing it. but almost all plugs i change or pull out look pretty black

Well no wonder there are so many Busa's getting atrocious fuel mileage.

If you guys are running rich enough it's robbing HP. Tune those bikes right!

As said above, you're running rich. Better run a little rich and leave some hp on the table than run lean though.......

I just checked the plugs on my Ninja and their a nice tan color. And it's carbed!

Come on now, FI beats carbs hands down in fuel control, so on a properly tuned ECU you should NEVER have the mixture lean enough to cause trouble. A Busa's plugs should look a lot better than that.

You're a little rich. It looks like water has been sitting around your plugs from washing your bike maybe?

I did have more open cans with no tune, that may have been why they were so black. I'm back to stock now. I got tired of the noise.

Told 'ya!

hummmm -- I thought less restrictive exhaust would lean it out a bit

My thoughts exactly...

 

[coeurdalenebusa]

so is that usually what happens? Put on some nice cans and they end up getting shelved due to the noise?
