let me guess, your bike is a 99 or 00? if so, they made an update on the carb in 2001 that is suppose to prevent this from happening. i would have the dealer look it up on the computer and tell you exactly what part it is. i think it is the pin that holds the float in place. however, i am not 100% sure. my friend had the same problem. he had the dealer put in the newer part and the problem no longer exists.

yup its a 2000 you dont happen to know the part number do u?
by the way thanks for the info

every quad does it, it empties out the float bowl so it doesnt flood the motor.

i have no clue what the part number is. my friend didn't even pay attention to what they did. if it was me i would have probably put in the part myself. now, if you stand the bike straight up, it may not run right for a sec or two. do you have stumbling problems when riding wheelies or up steep hills? if not, i think your experiencing what a normal carb does.

i agree with 250rider, the extra fuel is gonna come out of your carb bowl drain hose

thanks for the info i know that some fuel will leak out and that is normal however it never really felt like it wanted to stall when i put it back down on all fours until last weekend thats why i was wondering
thanks
any more info would be greatly appreciated
