Crank the throttle and watch where your accelerator pump squirts. It should squirt straight into the carb body towards the manifold. From the looks of things it looks to be squirting out of the carb into the air filter. Also do you have the crankcase vent hooked to the back of the air filter?

Re:carb leaking? Or 2 Years, 7 Months ago  
Couldn't tell ya. if float was too high, it would come out of the overflow tube I would think before it would rise up and out the needle jet. Only other gas flow there is the pump nozzle. Clean it up, lay a little talc down, and see if you can follow the path when it leaks. never heard of anyone needing to replace anything on this carb unless it was something they did. I know how I screwed mine up twice. lol Can always try to contact Mikuni tech support. Can't recall the head techs name, spoke with him a couple of times yrs ago. He knows the carb, he just didn't know how it was being jetted for Yamaha. He was surprised to hear how different my jetting was compared to the Hd's tho.

And no sir the vent is not hooked up. I just ran it down the bike wiyh a filter on it
