Ok just finished my 8th auto tune on my sporty and did a plug check after a spirited run of 50 miles, pulled the plugs and this is the color I got.
Bike pulls well through all gears , but still a little fluffy on a just cracked throttle.

Thoughts anyone?

I was thinking that myself, but was expecting a darker bisket color my self, so I was second guessing my self.

Thx Wiz

Very common mistake since the oil companies had to remove lead so we no longer get the coloring from the lead.
If you get the fueling to turn the plug “darker bisket color” it would be excessively rich and mileage would be terrible.

Ya so right there Bob cheers mate 👍.
After I made the post I did a little research on the web and found that ethanol blended fuels wash the color out of the plugs, but looking at examples on line I really didn’t think it would be that extensive.
I used to race 2 stroke karts and dirt bikes when I was way younger, And used to do plug chops / cuts to see how the brew was burning. Even different 2 stroke oil made a slight different color but this corn fuel changes the game alittle

Thx for ya input

Going to have to plug the PV into my notebook and pull up the logs on my last AT as I just exported the tune, saved it and flashed it to the ecm.
