Is the idle speed set too low? If so, adjust it, using the idle speed adjusting screw, to the correct idle speed (900 RPM). If that's not the problem, then check for air leaks between the carburetors and the engine by spraying WD-40 around the intake manifolds with the engine running. If there is an intake leak, the engine RPM will change briefly when the WD-40 is sprayed near it.
Aside from that, there are two other things that can cause your engine to die when it should be idling: the idle speed mixture adjustment, or low cylinder compression. Of course, if it was idling fine before, and the idle mixture adjustment hasn't been changed, then do a compression check, first. To idle properly, each cylinder's compression needs to be at least 140 psi.

Check the pesky fuel filter, or the carb for trash in the float bowl

Hi there!

Open up the carb and clean the jets with pressurized air. I also suspect water on the carburetor reservoir, before opening the carb, drain it first then run. Also, make sure the plugs are clean. Pull on the choke when twisting the accelerator, if it accelerates well, then warm the beast at normal temperature first before twisting the throttle hard again.

hope this helps-

If your battery is working well, You've got problem with either solenoid or starter motor.When you press the starter button, you should hear 'click' sound of solenoid, if not problem is in your solenoid ( I suggest for replacement). If there is 'click' sound but your bike will not crank, the problem is your starter motor. Now you need to check your carbon brush. Replace it with new one if you encountered abnormality.

The fuel petcock (on/off tap) has a rubber pad that the metal plate rests on against underside of tank. This has more than likely perished and become hard and brittle. Drain remaining fuel (if any) and remove the fuel hose and remove petcock retaining bolts. Carefully remove petcock as two fuel tube filters extend into tank. Replace the rubber pad with a new one. Might be a good idea to thoroughly check for cracking on all rubber components on the bike, especially fuel hose and brake fluid lines. Cheers.

If the leak is from the tank, check the gas line from the fuel petcock. If it turns out to be from the left carb, drain the bowl, it should free the float.

The main breaker panel is on the left side under the cover where the tool kit is located and the key opens it.

something to keep in mind. if the fuel filter appears to be empty, this may not always mean that the fuel system is running dry. if you bike runs fine i wouldnt worry about it. usually an air pocket makes its way into the filter and still allows fuel to flow. but if you are running into a fuel starveing problem. cutting out. ect. then after elimintateing the other possibilities you have listed you will want to check the carb venting tubes. if the float chambers are not getting proper venting from a pinched line or something then it will not allow fuel in as adequate as it should, and will cause running problems. or if this is something that occured after a storage period a sticking float valve can alter fuel flow as well. and last, if this tank has venting lines then you willl want to check them as well. venting problems can be tricky to find but they are a common cause of fuel starve problems.
