Why Do Engines Need A Carburetor?
Oct 01, · On 2-stroke dirt bikes, oil is mixed into the gasoline, something that allows the spark plug to foul out quicker than 4-stroke dirt bikes. Nonetheless, this is dependent on carb tuning. You’ll need to tune the carb on the rich side to hasten along the plug’s fouling. Avoid replacing the plug far outside the recommended heat range. Mixing 2 stroke fuel ratios for dirt bikes (premix) can be a royal pain in the jaxi, and more annoying than having to listen to Britney Spears on the office radio. However, it’s essential for two bangers and it’s something you need to do correctly or you’ll damage or even destroy the engine. I have spent many years tuning the jetting on my own 2 stroke dirt bikes. I started learning about jetting through the internet and have spent countless hours researching how carburetor works. This article will illustrate how your 2 stroke bike’s carb works in simple terms that’s easy to understand.
Read on to learn more about how a 2-stroke dirt bike works, signs that you may be neglecting maintenance, and some essential maintenance tips to ensure everything is working properly and you get to ride and enjoy your bike. A 2-stroke dirt bike engine fires and produces power, once for each revolution of the crankshaft.
That combination is compressed, and the spark plug ignites it, which results in an explosion. That action forces the piston to go back down, and the process repeats itself. The difference between these two engines is the combustion cycle process depends on the frequency the piston moves up and down during every cycle.
For a 2-stroke engine, the whole combustion cycle requires one piston stroke to be completed. There is a compression stroke and an explosion of the compressed fuel. The return stroke means the exhaust is let out, which allows fresh fuel mixture to get into the cylinder. The spark plugs will fire every single revolution, and this produces power once every two strokes of the piston.
However, for a 4-stroke engine, the piston completes two strokes during each revolution. That involves one exhaust stroke and one compression stroke. They are each followed by a return stroke. The spark plugs fire once every other revolution, and this produces power every four strokes of the piston. The 4-stroke engine does not need pre-mixing of oil and fuel as it has a separate compartment for the oil. Below are some essential maintenance tips.
The engine of a dirt bike plays a critical role in the overall performance of your dirt bike. They also have low output in horsepower and fire once each revolution. On the downside, 2-stroke engine parts wear out a lot. These engines also use more fuel, which means dealing with a lot of pollution. Failure to maintain the engine means you would need to replace the parts often, which is expensive.
Dirt bike engines are small and work more with high compression ratios. You should change the engine oil every ten hours of riding.
Pressure and heat can break down oil, and this leaves the engine vulnerable to heat buildup and performance loss. Changing oil on a 2-stroke dirt bike is simple. Air filters play a critical role in your dirt bike engine performance. These particles end up scratching the chamber and messing up with the piston and other parts. The air filter could also collect moisture, and that means interfering with air filtration. When checking your air filter pay attention to the filter oil coverage, and check for the presence of sand and silt.
A simple way to do this is to follow these simple steps:. Having sufficient coolant in the radiator is critical as this is what ensures the engine remains cool always. You may have changed your engine oil and cleaned out the air filter, but failure to have enough coolant could damage your engine. Make sure you have enough coolant before each ride. Flush the radiator and put some coolant. Another part you should never neglect when doing maintenance is the brake and brake pads of your dirt bike.
Front brake pads undergo harsh conditions and are responsible for most of the work. Having functional front brakes comes in handy when you are hitting the ramps since stopping distances are tight when competing. Start by checking the hydraulic system for adequate pressure or leaks. Simply grab the front brake lever and squeeze it to check for pressure.
Inspect the front brake system from the master cylinder to the caliper, while checking for signs of dirt accumulation or wetness. Another essential aspect of a 2-stroke dirt bike maintenance is the chain and sprocket care. Sprockets are critical as they help transfer power to the rear wheel through the help of a drive chain. The sprockets need to endure heavy energy loads and maintain structural functionality. With this regular stress, the result is constant pressure on the rear sprockets and countershaft.
The parts begin to wear out. Avoid riding on dry chains and sprockets as this only damages the bike. Inspect your bike for any signs of wear and tear in the chains of your dirt bike. In case of any tear, replace the chain to avoid any accidents.
Most transmission problems on a dirt bike start with the transmission fluid. The fluid resembles the engine oil as a few dirt bike models use similar oil in the transmission. Check to see if the transmission fluid is fresh and clear. A dark brown or black cloudy oil shows that the transmission oil is overdue for a replacement, and you need to replace it. Furthermore, you should always check the transmission fluid level a day before riding. Running the dirt bike with low transmission fluid could damage the internal components and lead to overheating.
Low transmission fluid levels also cause wear and tear on the clutch and gears. Check the manual to know the type of oil to use and when to change the transmission fluid. The pipes are prone to corrosion and rust due to exposure to weather and road conditions. Moreover, the part between the cylinder and exhaust spigot that contains the rubber O-ring is often overlooked.
Check the seal for cracks and other problems. Spokes often get lost, and also sometimes they can break, leading to a crash. In some cases, the spokes can get caught up in another part of the wheel. You need to check and tighten the spokes if you get a new wheel or when you have a new bike.
When it comes to inspecting the spokes, you need to avoid going through every spoke in a row as this could make the wheel get out of true. Another thing to note is to not over tighten the loose spokes as this could get the wheel out of true. Tighten the loose spokes equally to ensure that it stays in place.
A spoke torque wrench is a fantastic tool to help you tighten the spokes properly. The carburetor is the part likely to fail first if left unchecked. It keeps your dirt bike functioning at peak efficiency. Having a dirty carburetor affects performance, and this could make your bike fail to function.
Get the required tools before you remove the carburetor and disassemble it. You need to get:. Start by cleaning the carburetor. However, you need to be careful. The service manual will tell you the specific tools and their size required for cleaning. What you need to do then is to remove the carburetor from your dirt bike. Here are the next steps:. Does your 2-stroke dirt bike always become hard to start, or do you experience carbon deposits on the exhaust opening?
That could indicate an issue with your reed. Failure to check the outer corners and surfaces of the reed located within the reed cage could affect your dirt bike performance.
Monitor the reeds when you start experiencing problems with your bike. The other alternative would be to replace the reed pedals.
Remove the screws that hold the pedal in place and install a new pedal. All you need is a screwdriver. Use a thread-locking agent on the screws to fit them in place. Moreover, use a fresh gasket when installing the reed cage back in the motor. Cold spark plugs are used on high rpm engines, while hot plugs are used on low rpm engines. If you are having issues with fouling, you should use the stock heat range plug as a start point.
On 2-stroke dirt bikes, oil is mixed into the gasoline, something that allows the spark plug to foul out quicker than 4-stroke dirt bikes. Nonetheless, this is dependent on carb tuning.
Avoid replacing the plug far outside the recommended heat range. Remember that elevation affects spark plugs on 2-stroke dirt bikes because of tuning. That means it will foul faster when you overstretch your dirt bike limits. Some signs of a bad dirt bike spark plugs include:.
All of the above show that you are dealing with bad spark plugs, and you may need to replace them. Aging is one reason why your spark plugs could go bad. A bike that detonates gas too late or too early means that all the back pressure builds up on the spark plug. Fortunately, they are simple and affordable to replace.
Your dirt bike comes with fenders, mudguards, and side paneling. All these plastic parts help to protect your bike from debris and dirt. These plastics also come in handy in case of a crash.
