Drain the gas completely and try a different brand.
Install a NEW spark plug: CR8E or the Autolite 4303. Gap to .030.
After the engine starts, choke off ASAP. Then adjust your idle speed up a tad and let it sit for a couple of minutes before pouring the coals to it! After a two minute warm up, your off. Roll on the gas until the engine is good and hot, then whale on it.
These bikes are noted for leaking fuel into the engine just sitting. This would cause your next day plug fouling. Be sure to shut off the fuel, and “tip test” the bike to drain off gas in the carb bowl. Do this when done riding for the day.

I also would clean the carb. real good to eliminate
clogged jets.Take a fuel sample to make sure you
don't have dirt in fuel system/contamination.
As TK mentioned EK plug and always close fuel petcock.
Hope this gives you some help.

Your WR is now just broken in...What elevation are you at? You could try droping the needle clip a notch or 2 and maybe try a 170+ main fuel jet...The BK mod is strongly recomended. It would help avoid plug fouling and improve response too; I've adjusted my accelerator pump at .4 second at about 1/3 throttle, before engine was ever started, and have never fouled my CR8EK.

Gasoline quality may vary around the world, but the good old laws of physics don't.

However what I still do not understand is when I put the new plug in the second day and went for a ride, the first 20 minutes it poped and cracked really bad, as time went on the bike started to stop the loud poping and run better. So my question is, because of the colder weather I was running lean and it was poping like crazy, but when it really warmed up it stoped, just wondering why it stoped popiong, temp stayed about the same within that time period. Does the bike run a little more richer as it warms up? Also I am trying to remember if the poping was when I would be off the throttle, because if the throttle was closed and it poped, wouldn't it be the PJ that would need to be richened up or screw turned out?
