The Importance of a Throttle on a Dirt Bike
A throttle is a handle that controls the amount of air and fuel going into the engine. The more air and fuel that goes into the engine, the more power it has. That’s why the throttle is such an important part of a dirt bike. It allows the rider to control how much power they want to use at any given time.
How a Throttle Works
The throttle is connected to the carburetor, which is what mixes the air and fuel together before it goes into the engine. The carburetor has a butterfly valve in it that opens and closes based on how much you twist the throttle. The more you twist the throttle, the more air and fuel mix together and go into the engine.
Why a Throttle is Important
A throttle is important because it allows you to control how much power your bike has. If you’re riding on a rough trail, you might not want to use too much power so you don’t risk flipping over. Or, if you’re trying to get up a steep hill, you’ll need to use more power so your bike can make it to the top. It’s all about using just the right amount of power for whatever situation you’re in.
What causes the Sticky Throttle on a Dirt Bike?
You’re out on the trails, enjoying a beautiful day and putting your newly-cleaned dirt bike through its paces. Suddenly, you hit a mud puddle and before you know it, your throttle is sticking wide open! What gives? In this blog post, we’ll explore the most common causes of a sticky throttle so that you can get back to riding as quickly as possible.
One of the most common causes of a sticky throttle is debris that’s gotten lodged in the cable housing. This is easily fixed by removing the cable housing and cleaning out any foreign objects. Another frequent cause of a sticking throttle is corrosion or damage to the cable itself. If this is the case, you’ll need to replace the cable entirely.
If neither of these solutions solves your problem, then it’s likely that there’s an issue with the carburetor itself. The carburetor is responsible for mixing air and fuel in the correct proportions, and if it’s not working properly, it can cause all sorts of problems—including a sticking throttle. Fortunately, most carburetor issues can be fixed with a simple cleaning. Simply remove the carburetor and clean it with carburetor cleaner or white vinegar. Be sure to give it a thorough rinse afterwards so that no cleaner residue is left behind.
Simple ways to Fix a Sticky Throttle
A sticky throttle is a major hassle when you’re trying to ride your bike. Not being able to control your speed can be dangerous, and it’s also just really annoying. Luckily, there’s an easy fix for this problem. All you need is a little elbow grease and a few minutes of your time.
- Step 1: Remove the air filter cover. This will give you access to the throttle tube.
- Step 2: Use a Phillips head screwdriver to remove the two screws that secure the throttle tube to the carburetor.
- Step 3: Pull the throttle tube off of the carburetor. Be careful not to damage the O-ring seal.
- Step 4: Clean the inside of the throttle tube with a carburetor cleaner. Be sure to also clean the O-ring seal.
- Step 5: Reattach the throttle tube to the carburetor and replace the two screws. Make sure that the screws are tightened securely.
- Step 6: Replace the air filter cover. Test the throttle to make sure that it is working properly before taking your bike out for a ride. If you find that the throttle is still sticking, then you may need to replace the O-ring seal.
Conclusion:
A sticky throttle is annoying, but it’s easy to fix. Just wipe down the handlebar and throttle tube, and check the cable guide for any buildup. In most cases, that will take care of the problem. But if your throttle continues to stick, it’s time to take it to a professional mechanic for further diagnosis.
