What to do if dirt bike is flooded?


If there is a problem with the bike, the worst time seems to come. A flooded engine is no exception and can happen to anyone and their dirt bike. It’s not always comfortable to handle a flooded dirt bike engine, but it’s perfectly possible to take it yourself in your garage or driveway with a simple tool.

If your dirt bike is flooded then the simple way to fix it is, hold the throttle wide open, alomg with the hot start lever pulled in, kick it over 8 times. It will clean the cylinder which is flooded and finally close the throttle and kick it. It would be ready to work.

What to do if a dirt bike engine is flooded?

If the dirt bike engine is flooded, you will have to wait 15 minutes for the gas in the engine first to dissipate. If that doesn’t work, turn off the fuel tap, remove the ignition coil fuse, remove the spark plug, lightly place a cloth in the spark plug hole, crank the engine and apply excess gas to the cloth.

Of the many dirt bikes I own, most weren’t strangers to the flooded engine. I was able to repair this flooded motor many times, and it proved itself good. In addition to knowing how to fix a flooded engine, I can explain a few other things about a flooded dirt bike engine that may be useful in your situation.

Flooded Dirt bike Engine Repair Method

Flooded Dirt bike was a very frustrating situation, and I had a considerable share of it. When it first happens, it may look a little scary. The word “flood engine” doesn’t sound right. Sounds like a disadvantage for dirt bikes.

In most cases, a flooded dirt bike engine should not give too much alarm. This is a fairly common occurrence and can be easily fixed with proper steps. As I said before, I did this a few times myself and started as an amateur. Everything went well. If the dirt bike engine is flooded, the first thing to do is stop the engine from starting and leave it for at least 15 minutes. This allows the fuel stored in the engine to be discharged and/or discharged.

Some may be worried that the gas accumulated in the flooded engine may leak beyond the piston rings. This is because the gas mixes with the oil in the engine.

Some gases may bypass the piston rings, but don’t worry, the amount of oil drained and mixed is so tiny that it is not enough to change the oil concentration. However, if you are worried, changing your oil should help solve the problem.

In rare cases, when a dirt bike engine is flooded, too much gas can bypass the piston rings and mix with the oil in the engine. If this happens, it is due to a defective piston ring. This is because not too much gas should pass through. Bad piston rings also indicate that a large amount of oil has burned by that point.

Therefore, unless the dirt bike burns a large amount of oil, there is no need to worry about gas entering engine parts. In addition, while waiting, most of the gas that accumulates in the bottle can evaporate from the open valve.

If you wait at least 15 minutes and try to start the dirt bike to re-flood the engine, or if the gas does not appear to shrink, you should resort to Schedule B with self-draining of the cylinders.

To do this, the first thing you need to do is turn off the fuel tap. This will prevent fuel from being added to the engine if you start the engine in minutes. Next, you need to remove the fuse connected to the ignition coil (it is imperative not to skip this step).

Some say it’s too much to blow a fuse in the ignition coil, but I disagree. You may still be getting some current from the ignition coil flowing through the spark plug wire. While troubleshooting this issue, I don’t know what the hanging wire (or the hanging spark plug if it’s still attached to the wire) touches. Doing so may result in electric shock or grounding of the gas tank.

After removing the ignition coil fuse, remove the spark plug and check the condition. Ensure there is no corrosion and that the electrode gap (the space between the spark plug and the hook at the end) is respected.

Next, take some old cloth and lightly place it in the hole in the spark plug. The compression blows them away when you start the engine, and the gas splatters, so it’s important not to stuff them there. It not only catches the spray gas but also arranges it so that air can pass through.

Now you are ready to start the engine. This pushes the piston up and pushes gas into the cloth through the holes in the spark plug. After starting the engine for a few minutes, you need to remove the cloth from the spark plug holes, replace the spark plug and ignition cable, replace the fuse in the ignition coil, turn the fuel tap back on and start the dirt bike. There is.

Engine Flood Cause

You may have encountered several dirt bike floods while owning a dirt bike. Or maybe you just heard from someone else who has a problem. Of course, everyone knows that will happen, but many wonder how a dirt bike engine will be flooded in the first place.

When the fuel flows properly into the cylinder, the dirt bike engine will be flooded, but no spark will ignite the fuel. Therefore, the carburettor or injector (usually a carburettor problem) pushes in more and more fuel. Still, because there is no spark to ignite the fuel, the fuel stays in the cylinder and is eventually replenished. This is known as “flooding”.

Eventually, the fuel may not ignite even if there is a spark because the air-fuel ratio is so far apart. As a result, there is no room for air to create the right combination needed for combustion.

In a nutshell, the main cause of flooding in a dirt bike engine is a spark plug failure that does not provide the spark required for the engine to burn. Spark plugs are a simple part, but many of these problems can occur if everything is wrong.

The ignition coil and spark plug wire can also be the cause. If the ignition coil malfunctions, it will not send the correct signal through the spark plug wire and not instruct the spark plug to start sparking. Worn or cracked spark plug wires can cause power to flow through the frame and prevent the spark plug from sparking from the beginning.

How to find out if flooding of an engine is a problem?

There are hundreds of possible reasons why a dirt bike does not start. Therefore, it can be difficult to determine if the engine is flooded. However, some specific symptoms can easily indicate that engine flooding is a problem.

Of course, the first symptom is that the dirt bike does not start. The starting mechanism sounds perfectly normal, but no combustion occurs. The second-largest sign of engine flooding is the sudden smell of gas. When gas accumulates in the cylinder, it becomes easy to smell. The third sign to watch out for is that fuel is dripping or splattering from the exhaust. Finally, there may be water in the pipe. Therefore, when spraying a liquid, make sure it is a gas.

If all three of these symptoms occur, the reason the dirt bike does not start may be due to the engine being flooded. If you want more visual proof that your engine is flooded, there are several ways to do it.

The flooding of the engine is due to the lack of sparks from the spark plugs, so you can check the spark plugs yourself to see if they are sparking. First, remove the spark plug wire from the spark plug, then remove the spark plug from the engine and reattach it to the spark plug wire (just as the spark plug and wire “hang”).

Next, the end of the spark plug (the end of the hook) must contact the engine or frame and ground. Pay close attention to the grounding location. You don’t want it to be ground around gas or flammable chemicals or to the bottom. Do not ground the spark plug leads to the dirt bike tank.

Once the spark plug is grounded, stay connected to the spark plug wire and proceed to press the starter button (remove your finger from the spark). If the spark plug ignites, you know that the spark plug is not working. You can try this with all spark plugs. If all of them don’t work, there is probably a problem with the ignition coil. If some work and some do not, all spark plugs need to be replaced.

How to prevent a dirt bike engine from being flooded

As mentioned earlier, encountering a flooded engine is annoying, and you probably don’t want to deal with it again. However, there are several steps you can take when grooming your dirt bike to prevent the engine from flooding in the future. A major cause of flooding in dirt bikes engines is a defective spark plug. Spark plug maintenance is the key to maintaining the health of your dirt bike engine. Spark plugs should be checked at least once a year and replaced if they stop working.

Many people do not understand the spark plug gap’s importance at the spark plug’s end (the distance between the spark plug and the electrode or hook on the back). As a result, people often buy spark plugs from car stores, put them in the spark plug holes and call it good. This works for a while, but it’s not very efficient in the long run.

When purchasing a spark plug, the correct spark plug gap must be set at the end. You can buy a spark gap tool for a few dollars at any auto parts store. You should check the owner’s manual or online for the correct gap space for each spark plug on your dirt bike and use the tools to make the appropriate changes. Spark plugs are not provided as standard on all vehicles at proper intervals.

In addition to regular spark plug maintenance, the condition of the spark plug cable should also be checked regularly. If the wire is cracked or broken, it should be replaced immediately. This is because the opening in the wire can cause current to flow through the dirt bike itself rather than the spark plug.

How do I start the engine after flooding?

Perhaps the best remedy for a flooded engine is time. First, open the car’s hood and let the excess fuel evaporate for as long as possible. After about 20 minutes, try restarting your bike without accelerating. If that doesn’t work, you need to check the spark plugs. If the engine is flooded with excess fuel, the spark plugs can become flooded and unable to generate enough spark to start the engine. If you notice that the machine is frequently flooded, it is advisable to check the fuel injector and use a fuel injector cleaner.
