04 YZ450f high idle

I have a new stock 450. I went riding this past wknd and was doing alot of trail riding....When the trails required me to slow down and pull the clutch in the bike would still be idling somewhat high untill i gave it a burst of throttle and it would slow down...Bike is bone stock and have done nothing to it...what could cause this..thank :)

Please take a look at the search feature of the site. Or you could even look through the other posts. This was just covered recently. :)

Turn the idle screw down. It's the big black one on the left side of the carb.
