idle speed

Hello! I have a YZ 400 -98 and i´ve got some problems with the idle speed. After driving when i will let it running on idle speed the idle speed is pretty high and after about half a minute (maybe less) it comes down to normal. Hope that somebody can help me with this, Thanks!

Sounds like your a little lean on the slow circuit. turn out your fuel screw a 1/4 trun at a time and see if that helps.
