Doing that will tell you nothing, (bliping the throttle for 10-15 mins) except p*ss off your neighbours - if you have any.Is this a trick question test?
If it doesn't stumble anywhere, I'd be happy with those plugs. Mine never look better on a motor with 8K not so gentle miles on it. I don't have valve guide seals, so I'm burning little oil, and am slightly rich off idle with accelerator pump carburetion. That's what I attribute to the similar fuzzy black ring I see on mine. If I just blip the throttle in the driveway for 10 or 15 minutes, my plugs are darker everywhere. If I get it out and ride it, they look like yours upon return. I'm happy with how my motor runs. Not sure that means much, but it is as it is.
I noticed that too. But it looks more like a deposit rather than overheating maybe.Is there signs of insulator deterioration, like from excess temp?
Judging by the centre electrode, the ignition timing might be out, or is that the burnt gas covering it up?I would rather see a little less black around the rim but that doesn't really bother me. I would like to see the ground electrode at least a little more tan but that really doesn't bother me either. I don't like the look of the center electrode insulator. What brand/number are these? Does your gas have ethanol? They certainly look good enough to use.
Exactly.Under street riding conditions it's kind of impossible to learn anything other than really obvious over heating or oil and too rich
Definitely agree with that sentence. LOLWhoops, just reread the post, I'm talking to the wrong person...soz.
