Looks good to me. Maybe a tad rich but that gives you a little breathing room too.
As long as the bike feels good I'd leave it where it is.

Umm, you appear to me missing the outer electrode? And is the thread melted?!
Please try and upload some bigger pictures, but to me, that plug is wayyyyyyyyy ****ed!
Unless of course you cut the plug up to show us, then its pretty alright!

Properly jetted the burn ring should be 1-2mm and a nice chocolate color, correct?

Really?!?!? The plug has been cut away so that you can see the insulator easily. It is sacraficed as a tuning tool.

Normally the colours of what is actually visible is enough to tune your bike via spark plug, if you want any more than that then you are way better off getting on a dyno, installing a dial-a-jet, or going injection...
... remember, its only a KDX

Re: plug chop pics
The color of the visible portion of the insulator is only a general indicator of overall jetting. To do plug chops for the main a fresh plug is installed in a warm engine, and run @ WOT through the gears. The plug is then removed and cut or "chopped" as seen here so the burn ring can be read. This is an important step in properly sizing your main jet. Please see our jetting sticky for more info.kyledsmith87 wrote:Normally the colours of what is actually visible is enough to tune your bike via spark plug, if you want any more than that then you are way better off getting on a dyno, installing a dial-a-jet, or going injection...

Looking at the uncut end of a plug is just as good as asking people on the internet about jetting. Otherwise, people will be doing plug chops like this and possibly buying a handful of brass, then documenting one change at a time while maintaining the same gasoline, oil and ratio, etc. - real scary stuff.

Your butt dyno can work pretty good and some have a real sense for getting it just right using just that. Unfortunately, the majority of us just aren't good at doing it that way. For us mere mortals that can't do that, yet want our bike to run its best, plug chops are the most accurate way to accomplish our goal.kyledsmith87 wrote:Here's me using my ass to jet my bike... *sigh*...

My butt dyno is pretty good, and I use it to get close. I feel better doing a plug chop after just to make sure I haven't gone to lean on the main.
