If it were my bike (or my friends) I would take the carb off the bike and clean it out really well with carb cleaner and blow out all of the passages with compressed air. Then, it wouldn't be a bad idea to jet the bike completely stock, needle and all, just follow the manual. It's my opinion to start with a clean slate. Put it back together with a fresh CR8E plug and fresh gas. If that doesn't take care of it you might have an electrical problem but try this first for piece of mind.
I wish I had friends like you!!

Basically, I was replacing a plug after every ride. I ride in Colorado and all along felt it was an altitude jetting problem. On one very high altitude ride, I replaced it twice! The biggest problem was LONG downhills with little throttle but occasional blips to clear obsticles. Finally, I got the jetting right for Colorado (dropped the main a little, dropped the clip one position and dropped the pilot one size) and it ran great.
My other WR400 friends had to also drop the main and the clip, but for some reason, my bike was the only one that required a pilot jet change. But all the bikes are just a little different.
I don't know if this is your friends problem or what altitude he rides at. But I thought I'd share just in case.

My buddy took the bike to a shop in town about 2 weeks ago and had the carb cleaned and his fork seals replaced. The next time we rode he ran VP gas in the bike and it ran great.
We had been out about 4-5 times after the bike shop and the bike ran fine. Then one day he went to start it in the morning and we discovered the problem of not starting.
With the new plug in place, the bike fires on the first kick. Then when the bike sits it won't fire at all. We pull the plug and it seems to be fouled (black color with a bad smell of gas.) One of several things that I don't understand is why the bike will run fine with the new plug but won't restart after sitting.
I guess it is possible that the shop did or did'nt do something they should have??

Also, did you know that Bryan (that responded to your question) actually started the crazy website we know as "ThumperTalk"? Pretty cool....
Do as he says and get back to us.
