Title: How are my spark plugs?
Post by: Betlog on June 03, 2012, 06:10:24 PM
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.

+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.
