How to Unseize a Dirt Bike Engine
Introduction
If you’re a dirt bike rider, it’s important to know how to unseize an engine. Your engine is the most important part of your bike! You can have a million-dollar frame, but without an engine, it’s just a toy. But not all engines are created equal. It’s just like when you’re buying a car.
The more expensive the engine, the better performance you’ll get out of your bike. If your dirt bike is not running right and you don’t know why this article can help. Here I will explain how to unseize a dirt bike engine.
It will be broken down into the different parts of a dirt bike engine and how they work. You’ll also learn about what causes the dirt bike engine to seize up in the first place so that you can prevent it from happening again.
Why Dirt Bike Engines Seize Up?
The engine in a dirt bike can seize up if it is not properly maintained because debris is lodged inside the carburetor, fuel tank, or air filter.
Dirt bike engines seize up when they get too hot. This is the result of a buildup of carbon on the pistons, which can’t be removed by just spraying some brake fluid or something like that.
Required Materials
- Drain pan or bucket
- Gear puller (if necessary)
- Rag for wiping down the dirt bike after a successful unseating of the engine.
- To see if your dirt bike needs help, start by checking to make sure the problem is not in the clutch assembly itself. If so, then you need to replace the clutch.
- You will need some basic mechanical tools used for bikes. These are generally provided by the seller.
- You will also need hand gloves and glasses for personal protection.
Steps on How to Unseize a Dirt Bike Engine
There are certain steps included in unseizing a dirt bike engine. The user of the bike must maintain these steps chronologically for having the best performance from the bike.
Step One:
Drain the Oil and Remove the Cylinder Head Cover. Place an oil pan under the engine to catch any residual fluids that are still in there, then remove the cylinder head cover on top of your dirt bike’s motor. There will be bolts around this cover. Loosen these bolts with a wrench and take the cover off.
Step Two:
Drain the Transmission Fluid. Locate your transmission fluid drain plug on top of the engine, then remove it to let out any remaining fluids in there (typically just oil). Replace this plug when you’re done dripping everything out.
Step Three:
Remove the Piston. Get a wrench and use it to loosen the top nut on your piston, then take this off of its threaded base with another wrench. There will be some resistance from the force that has been applied to it by tightening everything back up when you finally remove it; just keep at it until you can get rid of this piece without any problems.
Step Four:
Remove the Cylinder Head and Clean It Up. Find where your cylinder head meets the engine block, then use a wrench to loosen this bolt that keeps them together. Once you’ve done so, take off the head of its base with another wrench or pliers (depending on how tight it is). When you’ve done so, take a rag and wipe off the inside of it.
Step Five:
Clean Up Your Spark Plug Wires and Reinstall Them. Take your spark plug wires out from their holder above the engine with some pliers or long nose pliers to get them loose enough that they can be pulled out easily after being unscrewed.
Once that’s done, take a wire brush and clean off the ends of each wire to get any dirt or grime out from it. You’ll also want to replace your spark plug at this time if you’re due for one, but otherwise, just make sure they are all tight in their appropriate places before moving on.
Step Six :
Put Your Air Filter Back On. You’ll want to put your air filter back on after you’ve cleaned it up and screw the cover in place with a little bit of sealant or glue so that it doesn’t come off again.
Final Step:
Fill Up Your Fuel Tank And Start It Up! Once everything is all clean and tidy, your engine should be back to its regular old self!
Precautions
- Be sure to check the air filter, oil level, and that your battery is strong.
- Lubricate the moving parts with a quality chain lube or grease.
- Use an electric starter (if available) to turn over the engine.
- Make sure to wear safety precautions while performing the task
- Do not touch the engine with bare hands.
