Mikuni Flatslide carb

['shee]

I bought my banshee with these flatslide carbs. if i leave my banshee for a while it will leak fuel out of the lower left vent tube. if i turn off the gas im fine. when i start it it will run fine. it will then die. when i do get it running i will fire one cylinder for a minute or two while under wot. after i burn the gas out it runs fine and i dont have a problem. could it be that my float is set too low. i think that my float is allowing the bike to choke but when warm it kills. any other ideas?

If you are getting fuel coming out the vent tube the float is probably stuck open or the needle valve is not sealling and it's overfilling the bowl. Just pull the bowl off and have a look.
