We all need more information than you are giving. List all your mods and jetting so somone with a WR426 can help you out. See my signature fo an example.

You probably need to lean your pilot jets and lower your needle. Give us a better description of how it idles, and how it behaves at 1/4 , 1/2 and full throttle while running. :)

Hey guys

It runs great after i get through warming it up. 1/4 throttle is fine 3/4 throttle is fine full throttle is fine. except when i first start riding 1/4 throttle is fine and when i starting gettin into higher RPMs is when it starts misfiring and junk. but after i ride for about 5-10 minutes just in lower RPMs it clears up. i am allowing it to warm up enough cause i let the bike warm up plenty. so it has been doing that till yesterday when i accidently let the bike go dead and couldn't crank it again cause i fouled the plug. thanks guys

Try going down on the main jet. You are most likely rich on the main. Go down about 5 units. For example: If you have a 160 try a 155 main jet.

Your dealer should stock those jets. It is cheaper then ordering from the web and paying shipping for one jet. :)
