This will allow the fuel to flow to the carburetor without the compressor blaring away. Step two is to grab a hand vacuum and fill the nozzle with gas. Step three is to attach the hand vac to the air compressor. All you need to do is run the hand vac or spray bottle gas over the carburetor. This will loosen any debris that may be in there. Step four is to clean the carburetor with a solvent-based cleaner. To clean the dirt bike carburetor with a solvent-based cleaner, you’ll need a cleaning tool and a few drops of grease.

Step-by-step instructions

1. Spray your dirt bike carburetor with gas. 2. Once the gas has completely evaporated, spray a thin layer of standard motorcycle fuel oil in the carburetor. Make sure that there is no oil around the holes or holes in the carburetor where you spray the oil. You’ll notice that the carburetor will take a minute or two to absorb the oil. If you need to, use your finger to keep the carburetor from moving while you wait for the oil to dry. 3. After the carburetor has absorbed the oil, re-assemble the carburetor so that it’s pointing down, then go ahead and fill it with gas. 4. Close the gas tank cap and put the fuel selector switch back in its normal position (if the switch is broken and in the on position, you can use the switch to select a gas-only mode) and fire up your dirt bike.

Disassemble the dirt bike carburetor

Before we go any further, you’ll need to remove the carbs from your dirt bike. Remove the rear main seal and the front main seal from the carb. They’re the two big metal pieces at the back of the carburetor. They’ll come right off when you simply pop them out. Do this first and then we’ll remove the rest of the carburetor from the exhaust system? First, place the front main seal between your hands so that the end is pointed down. Then lift up slowly. Once the entire front of the carburetor is off of the exhaust system, take a rag and gently wipe off the dirt that’s on the rubber gasket at the back of the carburetor. Make sure to go around the entire edge of the carburetor and also the rest of the exhaust system.

Put it back together

So how do you get the carburetor back together? Using the carburetor is as simple as you might think. The carburetor is held together with the spring and cam. To reassemble the carburetor, simply take the spring and the cam apart and put them back together. To remove the cam, unscrew the screw that goes into the bottom of the carburetor. Unscrew the small nut that’s attached to the intake manifold and then push on the cam and spring until it pops out. Now that the carburetor is back together, it’s time to fill it up with gas. To do this, unscrew the gas cap and put a gas bottle on the spigot, next to the fuel tank. The new fuel tank has to have enough gas to cover the air intake of the carburetor.
