Some parts are very easy to fix with these gas leaks and today I will talk about gas leaks on dirt bikes.

Why Does A Dirt Bike Leak Gas?

A dirt bike can leak gas for many reasons. Gas leaks are a very common disease on a dirt bike and are also very easy to repair or you can visit your nearest garage to fix it. Sometimes a gas leak can be a bad basket sign or a bad sign next to the Text.

Gas Leak Is Common Dirt Bikes:

One of the most common questions we get is a concern or a very bad smell of gas coming from the carburetor or leaking fuel in a bowl or overflowing. Both of these conditions are usually caused by a needle valve attached or worn. The floating needle valve is responsible for controlling the flow of fuel in the floating bowl.

When the tip of the valve gets old or debris prevents the valve from closing, the fuel flows continuously into the container thus causing the engine to overflow. Under extreme conditions, the gas can sink an air filter or overflow from the carburetor to the ground while standing. Another common cause is the use of gasoline containing any Ethanol. Many countries now include anything from 5-15% Ethanol that could be harmful to certain parts of the rubber over time.

How To Find The Gas Leak:

The first step to fixing a gas leak on your dirt bike is to identify the source.  For me, this starts with turning the fuel off and drying everything off with a shop rag.  Next, I will squat down next to the bike and turn the fuel back on. 

If there is a drastic leak, the source will be very obvious as fuel will spill out of one area quickly.  If it is a slower leak, you may need to wait until you see gas drops coming out of the overflow, or on the bottom of the carb.  Follow these back up to the source of the leak and then proceed.

Gas Leaks Out Of Carb Overflow:

If gas is pouring out of the carb overflow, then the most likely culprit is the float valve is either stuck open or has some debris preventing it from closing. Your carb will have a float in the bowl that rises with the level of gas in the float bowl.  This float is connected to a plunger which prevents additional fuel from entering the float bowl.

If for some reason this plunger is not allowed to seat in the float valve then gas will continue to come into the carb. Overflowing the float bowl and running out the overflow. Fixing it is pretty easy and involves taking the carb off your dirt bike, removing the float bowl (typically held in by 4 screws), and either cleaning or replacing the valve. 

Another quick trick is to try tapping on the carb bowl with the handle of a screwdriver to see if that knocks whatever is preventing the valve from closing loose.

Fuel Leaking Out of Float Bowl:

Another commonplace for fuel to leak is going to be out of the float bowl seal itself.  These leaks are generally slower than a float valve leak, and thus a little harder to spot.  These manifest themselves in wet float bowls, with no obvious sign of leaking.

How To Fix Gas Leak Of Dirt Bike Carburator:

To fix this, you will need to take the carb off the bike (or at the very least rotate it in place by 90 degrees to give yourself access to the float bowl screws.  Remove the float bowl and take a look at the gasket between the float bowl and the carb body.  This will generally be a rectangular roughly the size of a business card.

If the gasket looks crumbly, or a little worse for the wear go ahead and replace it.  Most carb rebuild kits come with one, but you might be lucky enough to just find the gasket for the float bowl for your carb if you look. If the gasket looks brand new, then chances are good that whoever was in the carb last time simply did not tighten the 4 screws holding the float bowl in place tight enough.  Go ahead and replace the carb bowl and tighten the screws to spec.
