Help me read these plugs
My last tank was only 30 mpg so I was wondering if the bike was running rich. It runs well but that mileage is too low.
They actually look good to me, electrode is still pretty sharp, but since I don't know how old they are, and since they don't cost that much, might as well replace them.
Perhaps my mpg is due to much of my riding being city, and when I am rolling, I'm rolling pretty fast.
Any other opinions on the plugs?

The threads were pretty dirty as you can see and they weren't very tight...can't imagine they were too loose but it is odd the threads were so dirty.
Just screwed a new set in. Felt like doing a project today and that's about as cheap as a project gets (besides cleaning).

All we can get in FL is 10% ethanol. They are pretty off white. My experience tells me the carb is tuned pretty well from the looks of them, and they both look about the same so that's also good.

They look rich for ethanol to me.

Here is a close up of the porcelain..
Don't look too rich to me but I appreciate the opinions.

Look great to me. This is mine with apx 10K and perfect..computered controlled. Runs just like new at 45K. Just got back from all day run. Those rusted ones are from salt spray in a freak ice storm/snow I got caught in going to FL in SC
