i was riding my o2cr250 tonight and as i was coming to this big jump the big went bwaoooooo. icased the jump but the bike stayed running every time i tried to give it gas it would do the same thing. so it took it back to pits checked my needle and main jets and my powervalve cables every thing seemed ok. so i started it back up and noticed if i turned throttle slowley it would rev up but turning the throttle fast it would bog. im hoping somebody can point me to a good place to start trouble shooting. could a broken reed cause this . its acts similar to running out of gas when you try to turn throttle fast. by the way it had gas in it. any info would help thanks
