My bike a 1110 1990 Virago V11 will start up, but leaks gas like crazy out of the air line

Make sure the fuel system is properly vented (gas cap, carburetors) Make sure the petcock will freely flow fuel, If this is a vacuum system, make sure you do not have any vacuum leaks!! The carbs sound like they need a good professional clearing, setting, and synchronizing!!

petcock could be bad

well if its a vaccum line there shouldnt be fuel there, i think your talking an overflow tube and no it shouldnt be leaking unless theres a problem, see a bike shop about his

The pilot jet controls the air/gas fuel mix at idle . If the jet gets plugged up not enough gas gets to the emgine at idle. You will need to remove the carbs and float bowls and clean them, paying special attention to the pilot valve. Count the number of turns to remove the pilot screw and replace the same number of turns then turn counter clockwise 1/2 turn.

A “very helpful” rating for this answer? Thanks!

Find out where the leaking gas is coming from. It has to go from the gas tank to the carb. Just follow the line. It may just be a hose is off or split or a gasket in the carb needs replacing. Not garbage. Anything can be fixed cheaper than buying a new one

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

the throttle body on the right side underneath is a spring and shaft.. well its gone all bronzie looking which tells me its been leaking for a while however now theres fuel drops on it and its stained the casings were it drips off to. So whats this mean? is there a seal in there that lets go or is something rooted?,If you're bike is under warrantee, take it to the dealer! Otherwise first step to me clean the area so you can examine the components, check throttle body balance and TPS and look for any signs of a bad balance situation (one pipe more discolored than the other, etc.). If the basics check out then put in some gas (i.e. not diesel) Fuel injector cleaner and a tankfull of good gas combined with a long ride at speed. Next I would change my air and fuel filters, drain the tank through a coffee filter, checking for resedue and repeating the process of FI cleaner, good gas, and a long ride.,,,
