Plug reading

If anyone has any thoughts on these plugs I'd love to hear it. No issues, just had them out and figured I'd start a plug reading thread. Jetting, as far as I remember from the last setup fiasco, 48 pilots, screws 2 turns out ish, 175/180, DJ Needle 4th clip with washer, HiFlo filter, 2Bros, 500 ohms, CBR coils, OEM springs.

Pump gas and plug reading is not possible due to additives,


Fresh plug and a can of VP or SUNOCO 100 and you might get readings worth something

Are you sure we can't tell that the timing is good and it is not burning oil? Or that generally speaking the AF is correct as evidenced by the insulator?

Well yes you can inspect them for physical damage, broken or blistered insulator, oil fouled ect..
but not "Tuning" with plug color as once used to fine tune jetting. It is not possible do to the additives in pump gas.
The days of doing a fresh plug, plug chop jetting test are long gone, unless your talking about a race bike using a known blend race gas

Opinions are like ******** mines no better then anyone else. Id be happy to be proven wrong, but hundreds of Dyno runs, plus years of knowledge taken from others leads me to my opinion.

Short answer. They look good. But..my credentials are not as extensive as Mr. Marquez's.
