Just doing my 1K service and decided to check plugs and gap. front plug was gapped a little to large, so put it back to spec.
These pics are at about 1.5K miles.
- always premium gas
- removed baffles
- XIEDs
- K&N and no airbox
If there is a better plug to use.. or any other suggestions let me know (different gap to use since i'm running xieds? etc)
thanks.
Looks just like mine at 1500. Mine is completely stock and dont have any performance upgrades tho, if your able I'd give it just a tad more fuel until the white on the electrode matches the rest of the plug.

Your plugs look better than a stock machine's plugs.
My stock XL1200X plugs are WHITE on the ground strap, and I do mean "OMG THAT IS F'n LEAN" white. The rest of the my plug is normal with flat black fuel deposits lightly dusting the face of the seat.
I still have to wait to be able to afford to modify and tune my bike, but I made a deal that I wouldn't buy anything for it until we closed on a house and I'm hunting for the right combo (gotta have a shop).
Looks fine to me. Plug reading is a lot harder than it used to be with the stuff they put in gas these days. You aren't really harming your engine where it's at, so if it runs fine I say stick with it.
As far as plugs, I noticed you had the HD ones. When you come to your first plug change, use Champion RA8HC plugs. They are the exact same ones that have the Harley-Davidson on them at a much cheaper price.

awesome, thanks guys.
i just didn't buy plugs, but wanted to see what they looked like. I know i'm pop'n on deceleration sometimes since I went with a better intake setup. It did look slightly lean.. but since it's EFI not much I can adjust there without re-map. which i might do anyways since i have a buddy that works at HD and he might just do it.
so i take it the whole "splitFire" era is done. back in my mustang race days, we used to run higher temp plugs to compensate for air/fuel ratios. it's been years and this is a harley... so i just don't see anyone talking about "higher end plugs" or hotter gap'n.
