How are my spark plugs?

[Betlog]

Hi guys,

I replaced my spark plugs maybe about 400~500 or so miles ago.  Today, I decided to pull them off to check.  How do they look to you (added new plug in the photo as a reference)?  NOTE: It's only been about 400~500 miles since I changed them.

Does it matter that I've only run the bike about 400~500 miles?  Wouldn't the insulator darken up with more mileage (at least I'm hoping so)?  Or will the insulator tips show engine color immediately after only a few miles?  I think most folks pull the plug out after a few thousand, not hundred, miles.

Color isn't the great indicator it was back in the days of leaded gasoline.  Your plugs are fine.

yeah, brush em off, regap and re install.

Got it.  Thanks everyone

+1.
Especially the upper porceline . Check the porcelin where it meets the bottom of the plug inside. You'll need a good flashlight, look for a tan or brown colored ring around the base or part way down inside.
