How many runs did you make on those plugs? You get false readings from plugs that have been run more than once....your looking for something JUST a little darker than that in my opinion but only 2mms from where it starts to where it ends in gritty....not the whole porcelain piece like is shown...

one of them i did the chop right then and there and 1 i rode up on and did chop on so i really do not know why they are like that.so there lean?

I think he was asking wether they were new, plug chop should be done with brand new plugs and both pulled after wide open throttle while moving, not sitting still

Here's a little vid taking you through it that a member here put together...

[Pasi S.]

Remember to warm up the motor real well with old plugs before plug chop run.

i warmed it up rode up with my old plugs put new ones in and got to 4th 5th gear fully open throttle 3-5 seconds clutch in kill switch let it roll to stop and pulled it out

guy.... forget about the plug chops... go with how it runs. jet up until it runs like poo WOT... then jet down 1 size at a time until it cleans up or you dont notice it running like crap.

 

 

throw in a 27.5 pilot set your air screw 1.5-2.5 turns and ride the piss out of it.

 

THIS!!!!

put 320 mains in rode for 10 mins this what plugs came out like

[KozyHeat]

Well, keep going higher than 320 until it is 'bogging ridiculously' Except this time it won't be Lean bogging, it will be four stroking ( firing every other stroke ) because it is Rich.

 

Then work your way down from there depending on your future mods and current ambient temperature

that almost looks like wash-out on the plugs.  first off, you need to be pulling like 12 second wot loaded run... and yes, you jet by feel/sound, but if you don't already know how, then doing the plug chops are a way to teach you and confirm that you are not just guessing....
