There are many types of throttles on the market today. Each has its own advantages and disadvantages, but they all serve the same purpose: to provide power to your engine. The most common type of throttle is the thumb throttle. This style of throttle is convenient because it can be operated with one hand. Can adjust thumb throttle on quad?
However, it can be tricky to adjust if you’re not familiar with it. In this post, we’ll show you how to adjust thumb throttle on quad. We’ll also give you some tips on how to get the most out of your engine by adjusting your throttle correctly.
How to Adjust thumb Throttle on Quad
Assuming you’re talking about a gasoline powered ATV, the process is as follows:
1. Locate the throttle cable on the handlebars. This is the cable that connects to the throttle assembly on the carburetor.
2. Loosen the adjusting screw on the throttle cable using a Phillips screwdriver.
3. Rotate the adjusting screw clockwise to loosen the throttle or counterclockwise to tighten it.
4. Test ride your ATV and make sure the throttle responds correctly. Adjust as necessary until you’re satisfied with the results.
How to Check the Throttle Cable Tension
Assuming your quad has a carburetor, the throttle cable is what opens and closes the throttle plate inside the carburetor. This controls how much air and fuel enters the engine, and therefore how much power the engine produces.
The throttle cable can become slack over time, affecting how well your engine runs. To check the tension on the throttle cable, you’ll need a few tools:
– A small screwdriver
– A set of pliers
– A ruler or tape measure
First, locate the adjusting screw on the carburetor. This is usually located near the throttle cable itself. With the screwdriver, turn the adjusting screw until it is loose enough to move by hand.
Next, use the pliers to grab hold of the end of the throttle cable where it attaches to the carburetor. Now pull on the cable while holding onto the end with the pliers. The cable should have some give to it, but shouldn’t be so loose that it slides through your fingers easily.
Finally, use the ruler or tape measure to measure how far away from flush with the carburetor body (in mm) that end of the throttle cable is sticking out. The ideal setting is usually between 2 and 4 mm. If it’s outside of this range, you’ll need to adjust accordingly.
How to Adjust the Cable Tension?
If your throttle isn’t responding properly, it might be due to cable tension. To fix this, you’ll need to adjust the tension on the cable.
First, loosen the jam nut on the cable. Then, turn the adjusting barrel clockwise to tighten the cable, or counterclockwise to loosen it. Once you’ve found the sweet spot, tighten the jam nut back down.
Now test out your throttle and see if it’s responding properly. If not, repeat the process until it does.
How to Check the Throttle Free Play?
Assuming your quad has a cable-operated throttle, there should be a small amount of free play in the cable. This is necessary to allow the engine to idle. To check the amount of free play, hold the throttle grip against the handlebar and push the cable in until it stops.
Then, release the pressure on the cable and see how far the throttle grip moves before coming to a stop. The ideal amount of free play is about 3mm or less. If there is more than this, you will need to adjust the throttle cable.
Conclusion
If you’re having trouble adjusting the thumb throttle on your quad, don’t worry – it’s a relatively simple process. Just follow the steps outlined in this article and you should be able to get it sorted out in no time.
And if you ever have any other questions about operating or maintaining your quad, be sure to consult your manual or reach out to a qualified professional for help.
