Default Read these plugs?
Ok, although I'm fairly mechanically inclined, I can't read plugs worth a ****. These are 9k mile plugs from my XL1200. Lean, rich, or just right?

Front:


Rear:


Thanks.

I'd say they're just right....at least I hope so. Mine look like that and I haven't had any issues with performance or anything else....20,650 miles and still good as day one.

They are identical. I mean the same exact plug in both pics.

Maybe a hair lean. Did you pull them after the bike had idled or was you running along and hit the kill switch? A plugs appearance can change in just fire inside the combustion chamber.

****... they may be the same plugs. I *might* have been drinking when I took the pics and resized the pictures. They look similar enough, from my recollection, that I don't think there is a big difference between the cylinders.

Anyway, the plug(s) were pulled, while hot, immediately after an approximately 30 mile run. I yanked the plugs in the auto parts store parking lot.

trust us, they are the same exact plug, down to the most minute carbon deposit.

Okay, well, I was definitely drinking when I took the pics...

Anyway, like I said, the front and rear looked pretty similar to my (drunken) naked eye. Based on the pic of whichever plug I happened to capture on film, how does it look?
