Motorcycles usually sit on a little kick stand on their left side. This makes it easy to flip them over. Maybe your motorcycle is outside and the wind pushes it, or it’s in the garage and you accidentally bump it on your way out the door.

You may have more issues than just scratched paint and bent brake levers when your motorcycle is thrown over. It’s not uncommon for a motorcycle to struggle turning over when it has just been knocked down.

Why won’t a motorcycle start after falling over? If a motorcycle won’t start after falling over, the biggest reason may be due to fuel delivery issues such as too much fuel leaking into the engine cylinders. A malfunctioning or disconnection of electronics may be the reason why the motorcycle won’t start after a fall.

Not being able start your bike after it is knocked over, is worse than it falling. Although there’s no way to fool proof a motorcycle to make sure it doesn’t fall over, we can take a look at a couple ways to make sure that yours stays upright as well as go into depth of why a it may not start if it falls and how you can fix it after it does.

Reasons Your Motorcycle Won’t Start After Falling Over

I’m sure that none of us want it to happen, but having your motorcycle fall over is only a question of whenmeaning if you haven’t knocked it over yet, it’s really only a matter of time. To look at the reasons why a motorcycle won’t start, we will begin by looking at the most common causes.

The most common reason a motorcycle won’t start after falling is because of fuel delivery problems. This will be a direct target for carbureted bike designs. You may already know that a carbureted bike operates by gravity feeding from the tank to a carburetor. Then it goes into the cylinders.

Sometimes, too much fuel can get fed into an engine cylinder if a motorcycle is damaged or knocked over.. The spark plug might not spark if there is too much fuel in any of the cylinders. This could be because the gasoline has made the connections too wet.

The reason this won’t happen to a fuel injected motor is because fuel is delivered and regulated by the computer. It doesn’t matter if the fuel was knocked over, the computer must signal for fuel to be delivered before it can enter the cylinders.

Apart from a flooded container,another common reason a motorcycle won’t start is because of an internal switch that has malfunctioned. There are a lot of sensors on a bike, and the newer the bike, the more sensors you’re going to find.

Newer motorcycles have kill switches that can detect if the bike is upright or laying on the ground. These switches are around so that if you are in an accident, or the bike falls while it is running and in gear, it’s not going to continue to run and possibly damage another motorist. The kill switch is there as a safety net for the motorcycle, and if triggered, won’t allow it to restart until the switch is reset and the bike is upright.

Finally, A disconnection in the motorcycle electronics could cause a no-start situation If it is dropped. There’s a lot of connections in a motorcycle that are needed in order for it to turn over. One of the most important connections is to the battery. For older bikes and bikes that are stored outsideCorrosion on battery terminals is normal. However, it should be cleaned up regularly..

If corrosion is severe enough on a battery, it can cause damage to the connection. When a bike with a bad battery connection falls over, it wouldn’t be surprising if the impact caused the connection to shake loose. So, in a condition where you don’t think it’s your fueling and/or the kill switch, check the connection that your motorcycle has to the battery.

How To Fix A Motorcycle That Won’t Start After Falling Over

So let’s say that you knocked your motorcycle over and it won’t start, what do you do next? Sometimes bikes fall over in the least convenient spots, but luckily, getting your bike going again shouldn’t be too difficult.

First, let’s look at how to fix your motorcycle if you suspect one of the cylinders is flooded. Like I mentioned earlier, it’s common to have a cylinder become flooded if your motorcycle is tipped over and it takes you a few minutes to bring it back up right. This is the best way to do it: Take out your spark plugs and dry them before putting them back in your bike. This is a great way to go, but what happens if you can’t reach the spark plugs?

If you can’t get to the sparkplugs, the best way to get your bike to start up is by trying to have it turn over with your hand on wide open throttle. You want to allow the maximum amount of air into the system at full throttle. Because there is so much fuel, it takes a lot more air to make a mixture that can be combusted.

This may take several attempts so be patient. After every start attempt, let everything cool for a minute or two so that you don’t damage anything. When it starts up, release slowly the throttle. It might take a little bit until all the extra fuel is burned up, so don’t just release the throttle as soon as it turns over.

As I have mentioned, your motorcycle’s sensor may have been notified that the bike has tipped. This needs to be reset before it can start up again. The most common way to reset the trigger is to power cycle the bike.

This is what it means After turning off the bike, take out the key and let it rest for a moment.. The switch should then be reset, allowing you to start your bike. If your bike still has trouble starting, there may be an issue with the motorbike itself.

How to prevent your motorcycle from falling again

It’s impossible to prevent all fall-over scenarios, but it’s important that we do what we can to so that we don’t have any silly mistakes. Your motorcycle should be visible from the road, but not in the way of heavy traffic.

That goes for whether you’re parked outside or in a garage or outside of a store or park. It is best to place it in a safe area that isn’t too close to pedestrians and other cars.. It is best to park it in a spot where cars can see it.

You don’t want them pulling into a spot only to see your bike too late and knocking it over, or having a car next to it open it’s doors and knocking it off balance. To make it stand out, you might consider placing a flat in a bright color.

Another common way your motorcycle can fall, other than when it’s parked, is when you come to a stop. Sometimes, stoplights are located on steep hills or bends along the road or even in a construction zone. Be aware of where you’re coming to a halt. Is the ground level? Are your feet on loose gravel? Always do what you can to be aware so that you don’t set your bike right down onto the ground.
