just finished putting an F3 together and started it for the first time. while idling, fuel is coming out of the air vent tubes in the carbs. what would cause a problem like this??

 

Not to sure on a bike, but my old banshee the floats in the bowls of the carbs being set to high would cause this. I can explain more if you don't understand, let me know.

 

Carb floats set too high... or the floats are seized up, and it's just filling with gas. How long as the bike been sitting ? Possible carb rebuild... not too bad of a job.

 

bike was sitting for about 2 years.. had the carbs out and cleaned all the jets, the floats were all moving freely. it only dumps the fuel out when first starting it up, but stops after running for awhile.. what does it mean that the floats are set too high and how do you fix that?? thanks in advance
