Again, maybe it means nothing at all but, when I see a white plug my eyes are rolling

Here we can see a brown or maybe red?... and a white plug.







The brown plug was in the head for a full season. (2007)

Now today I replaced the (2007) plug with a new one. Why? For fun.

Both are NGK BR8ES

One have a full season of riding (brown)

The other one (white) : 2 service hours.

So I have no question to ask tonight. Maybe tomorow?

So...what's the question?

Can we say if jetting is too lean or too rich just by seeing a picture?

I wonder if someone can read something on these 2 spark plugs?

I thought you needed to read the plug at the base of the porcelain to get a meaningfull reading...

You expect a 2 hour plug to look like a plug that's been run a year?

No no.

I just want to know if they look ''safe'' or normal ? Do your plugs look like this? I am just curious.

The part we need to see is covered with the threads

Ok. This was not really plug chop test. I will do a plug chop test soon with a new plug.

I'm sure you're OK. Just cut the threds off the one you already showed us (new one). Al longs as it's not pure white, you're OK....Unless you're going to the sand dunes.

The thread shell flat is another place to read air/fuel........but that's a color of a different horse.

This is what can be told from a close inspection of both plugs...magnifying them to huge proportions such that the ground strap fills the screen...after much musing, comparison to research photos, and consultation with experts throughout the motorcycle world. Here it comes....ready?.....

Don't worry about it.


You can 'see' some things...like, you don't want to try a BR10ES 'fer example. The ground strap is where timing issues are told, I recall. It looks like you don't want to advance your timing 10-15º to see how THAT works.

The plug on the right has obviously never even been IN an engine...'cuz we all know ('cuz we've been told over and over) that plug color indicates air/fuel mixture. There being no color to it...it's obviously never SEEN or been in the presence of an air/fuel mixture.

Ha! And you thought you could pull the wool over our eyes so easily......


And if most of this doesn't translate too well to The French, please do simply re-read what all the aforementioned research led to....namely, don't worry about it.

Understood

If he's french, wouldn't he need to retard the timing, instead of advancing it?

Re: 'If he's french...'

PUHleeze!! Let's show some respect and propriety!!! Some DECENCY fer crine out loud!!

That would be 'F'rench with a capital 'F'!!

My opinion, for what it's worth; I don't think there's a thing wrong with your bike based on the photos. The older plug shows some deposits most likely from fuel additives from who ever you buy gas from and the second plug confirms what the first one does; you are burning clean. Not too rich nor too hot.

The old wives tale that the plug insulator should be a chocolate brown is not worth much. If anything, a brown plug indicates that you are running "safe" in that you are probably too rich and too cold to harm the motor mechanically. Not a good way to get performance from a 2 stroke.....
