Please help with this spark plug
 

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!

Looks fairly normal to me, look at this link http://www.ngksparkplugs.com/tech_su...qs/faqread.asp

That is a perfect example of a plug in fine fettle. Don't worry about it! ;)

Good to hear! (I worry too much ;) )

What fuel are you using, Ethanol or unleaded? As the red green tinge is from metal additives been added to fuel to raise the octane rating.

I use plain normal 95 octane unleaded fuel.. Not ethanol.
But I think the swedish petrol can contain some percentage of ethanol.. About 5%.. Is this bad for the engine?

I can not see this green/red tinge on my plug, more than on the photo..

Edit: looks like Swedish petrol stations are nowadays allowed to put in up to 10% ethanol in the 95 octane unleaded gasoline.. But I don't think it is more than 5% ethanol in it yet.
Perhaps I should get 98 octane unleaded gasoline instead of 95 p, or even 99 octane?

Would the Tenere run with pure Ethanol or with E85?
