My bike started acting like the float valve was stuck open. It was dumping gas all over from the vent/overflow line. I noticed it running real rich, looked down and gas was dripping excessively from the vent tubes. It even ran out of the air cleaner side plate vent like it was backing up and coming out the intake. I took apart the carb, visually inspected and put back together there on the trail. It quit leaking so I figured problem fixed. I started hammering down the trail and again, at my next stopping point, my bike looked like it was taking a piss from the carb overflow vent. It seems that as long as I'm putting along (read: no fun) the bike works fine, but as soon as I hammer down, float valve sticks open and floods out the bike. I'm going to replace all internal carb parts I think unless someone can help me out. What could be causing my problem? Thanks in advance!!!
