Now this has happened two times before in the morning after I rode the bike for a short time , 3or 4 blocks and then shut it off and started it up again. Then all I had to do was open her up for a bout a mile and the bike would run fine after that. I noticed some white foammy stuff comming from the breather hose both times after I parked the bike.
Back to yesterday. It took almost 10 minutes of trying to keep the bike running before it started to run better again. I haven't had enough time to look at the bike since, so I don't know if the plug is fouled or if white foam is present in breather hose. I am hoping to tear into it tonight but asside from checking the plug, air filter, I am going to dump the bole on the carb as well. Any other suggestions will help.Thanks

Then post your jet sizes and the bikes engine, exhaust and/or carb mods, be specific, ie, Dr D pipe, WR timed, 168 main jet, etc, etc and you'll get the help you need.

Hopefully your fix is this simple.

This is happening comming down out of elevation, right??? Your loading up your plug, thus causing it to run bad, backfire, and all that good stuff. Guess what, your jetting is a little off. My bike did this ALL the time. I would start at Ned, and ride up to like 12K, and on the way down, if I didn't conciousely keep a little throttle going (ie. not engine breaking all the way down), I could usually avoid this. I made a consious effort to always be on the throttle a little bit, and usually could get away with that.
Bottom line is, you don't need to be putting up with this. If your uncorked, and uncovered, throttle stop and what not, go to YZ jetting. I rode this weekend, both days going from 8K to 12K and back, no loading up what so ever. However, since I was running rich up at 12K, if I tried a bunch of hard acceleration things, wheelies and what not, I was able to start loading the plug that way.
You don't have a hard or expensive fix ahead, but unless your going to "just deal with it", I would start looking at your jetting, Oh, and as Bill suggested, clean your carb too .
Let me know if you need anything, were not to far apart.

I didn't have the hot start out I already figured that one out the hard way.
Dodger, I was comming down from elevation and I was on and off of the power quite a bit, jumping some nice new waterbars in the road before it started to run crappy.

Still, for some reason, your loading up your plug even thought your staying on the gas. Hmmmmmmm............Why don't you pull the carby, and note your jetting. I think you may be lean loading the plug, but would need to see your specs.
On the needle, yes it's marked, yours will probably be a DMM, marked just under the clip positions. When marking your clip position, with the tappered end of the needle pointing to the ground, clip #1 is on top, and the number increases as you go down the needle.
Let me know your set up, mods and jetting, and lets see if we can fix your little problem.
