reduce the size of the main jet, not the pilot 3/4 to wot is were main jet size is the biggest factor. Unless its smoking and doggy at WOT I wouldn't worry to much about mid 10's for afr. Plug looks alright, and if your not having problems fowling the plugs I would stick with the colder plugs.
Have fun!

main jet needs to be smaller.

i know the main jet will cut it down, didnt know what size... nor if i was over looking something else.....honestly you could never tell its running rich by how its running..... it feels dead on! but obviously i want to what i want out of my "investment" and have as much pony's as i can.

I would say your not going to notice a difference between 10.5 and 12(I wouldn't go any leaner) . Factory bikes often run this rich, or richer out of the box at wot. The needles are aggressively stepped for lean cruse, and rich wot.
Your going to have to remove your jets, find out what size/type they are and buy a few different sizes. It might only take one size smaller, it might take 3 sizes smaller.... Who knows maybe tomorrow the weather is different and its running bang on.
