Hello, I'm doing some maintenance on my bike and checked my spark plug..
I have difficulties to determine if this is normal or if it is running hot? On the pictures I have seen the difference is quite minimal?

How do you think my spark plug look? If it doesn't look ok, in my case, what can I do in the engine to make it ok? I have seen pictures on spark plugs should be pretty white to chocolate brown. And hot spark plugs are also quite white..

Should I richen my fuel mix more? (I have a GPR PowerJet and Kevs O2 controller installed along with K&N Filter and BSM Slip-on.)

3 pics of my spark plug;





Thanks in advance!
