I have a 2004 banshee 350 and im leaking fuel from overflow when i open my throttle and when my petcock is on. Im also smoking white from throttle side.
Ooppsss.. FIRST - get the carbs cleaned and set by a factory trained tech!! That will clear up a lot...if it continues to smoke out the right side.. your right side crankshaft oil seal is probably leaking.. use a professional!!!

Hi Jwelden,
Have you checked the float level in the float chamber?
I guess you may have to reset the float pin adjustment, its allowing more gas to pass through thn required and thus the overflow!
Not bad too, when you are working on the float assembly take the opportunity to blow out the fuel line from petcock to the carburator via the seat for the float pin,any foreign particals there would stop the float pin to seal up and thus overflow.
Fit in an inline fuel filter , this will help keep out the dirt or whatever.
Hope this helps.

yes, the breather line hooks to the petcock on the line facing the back, the fuel line hooks to the larger one. the line from the breather is actually a vacume line that turns on the fuel, without it you will not get fuel out of the petcock unless it is in the prime position.

My bike started doing the same thing. I pulled the carbs put new kits in them and it still does the same thing. It does not seem like a spark issue because the fuel consumption would not be this bad, but the floats looked good. The needle valves and seats are new. I am not sure what to think at this point. I even replaced the intake manifolds and flushed my fuel system. It starts good initially. It is almost like the fuel pump is pushing to much pressure and over coming the needle valve. Has anyone seen this before?
Thanks,
SOURCE: banshee wont rev
Usually related to TORS, specifically the safety switch in the clutch/park brake assembly. If it's defective the engine won't rev. Solution: look for a TORS removal kit.

I have a 2004 banshee at the yamaha dealer being worked on.It would not run when i took it up there they cleaned the carbs and put it back together it will start but when you rev it, it holds itself wide open and wont shut down unless you pull the plug wires.they also checked the floats in the carbs said they where ok. they think it is a vent issue with the gas tank or the fuel shut off valve.IS THAT POSSIBLE
