Question about 1990 Yamaha XV 535 Virago DX
I have not had this bike too long so I am not too familiar with what I'm looking at, but the canister that houses the filter for what I think is the fuel system has fuel pouring out from it. It looks as if fuel should go there but I do not see its practicality since there is no where for it to go.

Annon, You would not be the first Virago owner to have carburetor float sticking or dirt under the needle. If you are comfortable doing so, remove carbs. and clean or rebuild or have a good Tech. do it for you. "I hope this helped you out, if so let me know by pressing the helpful button.

Hi, Anonymous if you ever see gas weepage from your air cleaner after a putt you may be suffering from fuel reversion or standoff. This is a common end result when changing air cleaners, camshafts, and or exhaust systems or mufflers and not using the proper combination of parts that will not give you maximum performance. Basically, what happens is you have upset the delicate balance of the speed in which the air/fuel mixture enters the combustion chamber. If you change your mufflers the exhaust pulse/charge leaving the exhaust valve hits the baffle and bounces back to the exhaust port putting up a different amount of resistance to the next outgoing pulse/charge depending upon the baffle design. This negative situation can sometimes be remedied by installing reversion/torque cones. If you change your carburetor it may create a virtual wall of fuel, that can be viewed by removing the air cleaner, too be spitting back towards the air cleaner. This negative situation can sometimes be remedied by installing a longer intake manifold. Camshaft induced reversion can only be fixed by using a different cam with the proper amount of duration and or overlap. This phenomenon is more noticeable at higher RPM's and can really rob power and performance from a really great ride.

Probabilly a stuk carburettor float or needle.
Try to solve this problem to gently tap on the carburettor bodies. If this doesn't help you have to clean out the carburettors, and/or replace the float neeldes

Tips for a great answer:
P0443 The fuel vapor canister reduces that gas smell on hot days outside/inside of car. The fuel vapor canister fillers bad smells from gas tank on hot days when the gas expands and burps fumes through carbon canister filter. From the canister (gas vapor fumes) goes back into the engine to be burned again...it's a closed loop for vapors to be recycled though engine. Don't worry, once the carbon canister dries out and no longer flooded with raw fuel the code should go away...just don't let the top off fuel tank back flow into the 'Evap emission control' carbon filter near the top and close to the gas cap...:)
