So my bike's been running without incident for almost two weeks now! Until I went to ride to work Friday...

Bike was only running on one cylinder. I did my due diligence and checked coils, points, and wires before finally switching the plugs and realizing that I had a faulty plug. The plug was only 2 weeks old, and the electrode wasn't fouled. It looked fine, just didn't work.

Have you guys seen this? I guess I've never had a plug go bad on me before. I bought a box of 10, and I'm keeping a spare along with the proper wrenches in my toolkit now.

Plugs are NGK B8ES.

Yep, I've had it happen to me. It'll make a fool out of you because "It can't be the plug, it's almost brand new".

I'm trying to determine whether I should take it as:

a) an isolated incident, not something to worry about

or

b) signs of a deeper problem with the potential of a repeat failure

Is there anything that could be wrong with the bike that would cause a plug to fail, or should I just chalk this up as one of the countless "I've never seen this befores" that I've had with this bike?

I run into this myself, more often these days than in the past.
Maybe they're made in China too these days, like nearly everything else......
Just keep it in the back of your mind.
What sort of gas are you running?????

I run 93 octane from Mobil or 94 from Sunoco.

I run 93 octane from Mobil or 94 from Sunoco.

That should present no problems.
Wow, you still have Sunoco stations?? Cool.....

Fact is, the NGK's we use are probably made right here in the USA now - maybe we'd be better off with chineeze plugs??

I've thought about going to an iridium plug, or going to the next hotter plug (B7ES I believe), but figured it would just be a waste of money. Just as long as the bike doesn't start eating these things left and right, I'm sure I'll be fine.

If it was me I would just forget it unless it becomes a chronic problem. I assume the plug had no funky deposits on it? (oily, black, or thick?)

Nope plug looked just as it should. Thanks for the advice.
