Sparkplug analysis !

[KTy]

Do you think the grey ring on the outside of the center tip is suspicious ? :plemplem:

I suspect it could be the cause of some *small* *occasional* troubles at high-rpm...

And yes, I'm running too rich. BUt what matters to me is this "grey" ring....

It's a B8HS NGK running on a stock PX125E.

Thanks

edit:

heard this grey ring comes from additives in modern fuel.

i'm not quite sure about this.
