Hey all, Just got my new 2008 WR450, after break-in i went off road and was winding the throttle on smothly it went fine but when i went to go from throttle closed to 3/4, full open or there abouts (to pop the front up ) it bogged on me for a couple of seconds then re-gained power... is this jetting? or the AIS? What will get rid of this? No free mods done yet. any help would be awesome thanks. Cheers.
