The most common issue with leaking fuel is the needle being stuck open. Usually this is from dirt or other foreign material getting into the fuel system.
Also, if your bike has been sitting for awhile, gas will gum up and clog the needle jet.
Your best bet is to remove and clean the carb.
Check to be sure fuel has not run into the crankcase and diluted your oil. If it has, change oil immediately. A good way to check is to open the oil fill plug and smell the opening.

Liberty 50 2t fuel leak when starting. a heavy fuel leak down over the flywheel and onto exhaust when standing or more extreme when starting.

Fuel float in carburettor maybe set to high! causing Needle and seat not to close! hence letting fuel flow from Over flow pipe in carburettor.

Turn fuel on then off to start engine once engine running turn fuel on again.

But best to adjust fuel float height, its just a tiny bend you have to make on a brass tab to stop fuel flow when the float gets to a certain height! in the fuel bowl of the carburetor.

sounds like you have got worn piston rings/barrells the excess gap is alowing the fuel mixture in yhe bores to leak past down into the the oil- engine may need major overhaul as this will only get worse

Runs as if it is flooding black smoke and missis

It sounds like a stuck or worn needle in the carburettor. It is like the ball valve in your toilet. If it is you will need to replace it and the seat. It is inside the carburettor and allows the right amount of fuel into the fuel bowl. Over time the it wears and the needle does not sit properly in the seat so it leaks. Some times it wont close properly if it becomes gunked up. If the needle sticks open the carburettor floods and nothing works properly. It is a simple enough fix to do yourself but a good mechanic should be able to sort it in about half an hour.

2003 yamaha roadstar leak fuel sometimes after I shut it off I think the floats are sticking any solutions. Rick

Yes Rick, try a couple of tricks I know.First,open the carburettor drain screw located at the base of the carburettor,this lets fuel flow out of the carburettor drain located next to/under it.(To acces this drain screw look between the engine cylinders from the LEFT of the bike)While the fuel is draining out,tap the fuel bowl.Next re-tighten the carby drain screw and see how that goes.I would suspect your bike has a vacumatic fuel tap that has 3 positions on it.1 marked on, 1 marked res, 1 marked pri.If the fuel leaks occur when in the on or res position this means part of your problem is a leaking diaphram in the fuel tap.Replace this & when engine isn't running,no fuel can flow to the carby when it's in the on or reserve positions.After ensuring the tap is ok, and trying the first trick,if it still leaks,well then you'll have to pull off the carby and give the needle and seat a clean.
Hope this healps Regards Andy Porrelli

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
