spark plug condition?

[WrAtHs]

Someone metioned something in an old post I saw about a link on exriders that showed different examples of spark plugs and how they should look under proper air/fuel mix. Does anyone know that link?

I have a stock 400ex and the plug is bone dry and white. Sounds like its too lean...


thanks :)

Here is a website that has good pictures for plugs. He says he got it from NGK.
