Lean usually gives you the common popping on decel that WR's are known for.
Lean also means it will run hotter and have a better chance of overheating in the tight stuff, so go for Rich if anything.

These are some of the one I've experienced, I'm sure some others on here could give you a complete rundown of all of the symptoms. Looking at the plug is a good idea, but there are symptoms of being lean/rich at small and large throttle openings, as the carburetor uses different circuits, that may not be told on the plug.
Hope this helps

A well jetted 2 stroke will make very little smoke and will run very clean. It will also have a bit of a different sound, rich jetting = dull exhaust sound, nice jetting = more of a tinny sound.

These bikes are actually easy to jet. The problem comes in that for some reason, some really wierd inexplicable reason, people have this urge, this drive, this wild fascination with jetting these bikes overly rich.
Stop the madness.
One; Change only one jet at a time.
Two; If your plug looks rich, it is.
Three; If you puff black smoke, see Two.
That mysterious midrange surge in 1/2 to 3/4 throttle, where it feels like its cutting out and misfiring, you know what I'm talking about....that's a rich needle and/or main.
Thus you need to investigate the possiblity of leaning things out a bit.
Remember your AP? That makes you , NAY, requires you to jet your needle properly.
Quit screwing with your TPS systems and jet your bikes correctly.
You'll also never foul a plug again. Won't that be nice?
