Motorcycle Engine Blow-Up: 5 Common Reasons (Explained)

Even if you are riding your bike without giving it proper rest, it can hit you hard when the motorcycle engine blows up. An engine failure doesn’t have a warning sign, and it’s up to you how you maintain your vehicle to prevent it from distortion. 

I’m here to pull you out of the problem associated with the engine. First, you need to understand how it will be damaged; only then will you be able to find the solution. I have mentioned some important causes and prevention along with other information. 

Why Do Motorcycle Engine Blow-Up?

There are several reasons behind engine failure, but your awareness can prevent it. Know the causes and try to give your best so that you won’t have to invest more in repairing or you may need to buy a new engine. 

1. Overheating

Overheating is one of the most typical factors that leads to the breakdown of a motorcycle’s engine. When the temperature inside of your engine reaches a certain point, the metal components can begin to bend and eventually break.

This can lead to an explosion, which occurs when the pistons explode inside of the cylinders. In most cases, blown engines require either a full rebuild or replacement altogether.

 You can help prevent your engine from overheating through regular maintenance and keeping an eye on your coolant levels.

If your engine starts to run hot, pull over and let it cool down before continuing on your trip. It’s also a good idea to avoid riding in stop-and-go traffic when it’s hot outside since this can strain your engine.

2. Insufficient Amount of Fluid

Another common cause of engine failure is improper lubrication. Your motorcycle’s engine needs a steady oil supply to keep all the moving parts properly lubricated. If oil levels get too low, or if the oil isn’t clean, it can cause significant damage to your engine.

Always check your oil level before riding, and change it according to the manufacturer’s recommendations. Also, look into the clutch fluid level; it will damage gears or transmission as they need to work hard while riding.

Steering fluid is also essential; continuing riding without checking the steering fluid will destroy the steering pump.

Two more parts are imperative, too, brake fluid and windshield fluid; check the level every time you fill the tank at least once. 

3. Continue Riding

If you ride hard and push your motorcycle to its limits, you’re more likely to experience engine failure at some point. That’s because high-performance engines work much harder than average engines and produce more heat.

 If you want to avoid problems, make sure you give your bike a rest after a few challenging rides so that it has a chance to cool down properly. And don’t forget to do regular maintenance; take care of it as you take care of your beauty. 

4. Starting a Motorcycle Without Warming it Up

If you reside in a place where the average temperature goes below 0°, you should use an engine heater. Cold starts can damage most of the parts of your motorcycle, like the battery, starter, pistons, cylinder rods and heads. 

Buy the heater and connect it to the radiator; it will protect your engine and help you start the bike even in the harsh winter. You don’t need to carry the extra burden of warming it up; the engine heater will do the task. 

5. Incorrect Amount Of Ethanol

Adding Ethanol Gasoline is one of the causes of engine damage. Using Ethanol over time will lead to internal rusting as it absorbs water.

Whenever you store Ethanol, make sure it won’t create bonds with the water; most of the time, keeping it improper acts as a reaction catalyst.

Water could corrode fuel lines, valves, rods, cylinders and heads; on the other hand, Ethanol contact with rubber and plastic parts can lead to damage.

To avoid engine failure, use fuel additives to prevent corrosion and other causes that could put your bike in bad condition. As fuel and coolant are important for your vehicle, fuel additives are equally essential. 

What To Watch Out For Engine Failure:

The most common cause of engine failure is a loss of oil pressure. This can be caused by various factors, including a failed oil pump, a clogged oil filter, or an oil leak. If your motorcycle is leaking oil, it’s essential to have it checked out by a mechanic as soon as possible.

Another common cause of engine failure is overheating. This can be caused by various factors, including a stuck thermostat, a leaking radiator, or a blown head gasket. If your motorcycle is overheating, it’s essential to have it checked out by a mechanic as soon as possible.

If you notice any strange noises coming from your motorcycle’s engine, it’s essential to have it checked out by a mechanic as soon as possible. Strange noises can be an indication of serious engine problems.

Finally, if you notice any unusual vibrations coming from your motorcycle’s engine, it’s essential to have it checked out by a mechanic as soon as possible. Unusual vibrations can be an indication of serious engine problems.

How To Fix a Motorcycle Engine With Simple Methods:

Well, there are a couple of totally different reasons for equipment failure. Here are some tips on how to fix a motorcycle engine if it does blow up.

1. Check Oil Leakages

If you have an oil leak, you first need to find the leak’s source and fix it. A blown engine usually has low oil pressure, so check your oil level frequently.

If your motor runs low on oil, it will start to overheat and eventually blow up.

2. Inspect Connections

If you suspect that an electrical issue caused your engine to blow, the first thing you should do is check all of the fuses in your vehicle.

If they are all in working order, you need to inspect the wiring harness for any wires that are damaged or loose.

When you have located and fixed the issue, you should have no trouble starting the engine after you have completed the necessary repairs.

3. Replace Piston Rings

If your engine has blown up due to overheating, you will need to replace the piston rings. This is a relatively easy repair that you can do at home with some valuable tools.

However, if you are not comfortable doing this repair yourself, you can always take it to a mechanic or dealer, who can do it for you.

If there is no oil on the dipstick, or if the oil level is low, add more oil to the engine and try to start it again. If the engine still won’t start, or if it starts but then dies right away, you may need to call a tow truck or take your motorcycle to a mechanic.

If the engine fails while you are riding your motorcycle, it can be a hazardous situation. The engine may lock up and cause the bike to lose power, which can cause you to lose control and crash.

Does A Failed Engine Affect The Frame And Handlebars?

A blown engine can affect the frame and handlebars of your motorcycle. If the engine fails while you are riding, it can cause the bike to lurch forward and possibly tip over.

The force of the engine blowing can also cause the frame to bend or break, and the handlebars can wrench from your hands. In short, a blown engine can cause a lot of damage to your motorcycle.
