How to increase the speed of your EZ-GO golf cart in just 5 minutes.

Want your EZ-GO golf cart to go faster to save travel time or enjoy a more powerful driving experience? The good news is you can increase your cart's speed from 24 km/h to 35 km/h in just about 5 minutes – absolutely no complicated tools or advanced techniques required.

In this article, you will learn how to adjust the governor – a simple and effective way to safely increase your car's speed by 8 to 16 km/h.

Easy tips for speeding up your golf cart.

If you want your golf cart to go faster without changing the engine, try these simple steps. No advanced technical knowledge required!

1. Identify the governor.

• Locate the speed governor on a golf cart's 4-stroke engine.

• It is usually a small spring wrapped around a metal rod.

2. Adjust to increase speed.

• Loosen the small nut on the spring.

• Tighten the larger nut to increase the vehicle's speed.

3. Set the desired speed.

• Once you've reached the desired speed, tighten the small nut to secure it.

4. For other types of vehicles

• If the vehicle doesn't use a 4-stroke engine, adjust the small metal rod near the clutch pedal to improve acceleration.

Note: Adjustments should be made carefully to ensure safety and avoid damaging the engine.

Part 1: How to adjust the EZ-GO golf cart speed controller in 5 minutes

Step 1: Easily increase the speed of your golf cart with just one spring adjustment.

• Speed ​​limiting spring: Most golf carts, especially the EZ Go series (which accounts for 90%), have a spring in the motor that helps limit the maximum speed.

• How to increase speed: To make the car go faster, simply locate this spring and tighten it slightly. This will allow the engine to increase its speed.

• Note: Some newer car models may be more difficult to adjust due to different designs, but this is quite rare.

Step 2: How to open the seat to adjust the golf cart engine.

• Step 1: Raise the seat.

• Step 2: Remove the seat cushions to expose the engine underneath.

• Note: With newer car models, you may need a screwdriver to remove the seat because it is bolted on more tightly.

Step 3: Remove the plastic cover to access the golf cart engine.

• Step 3: Remove the screws on the black plastic panel behind the seat. Most models have about 5 screws.

• Step 4: The motor is located at the front, right under this plastic panel. Once removed, lift off the plastic cover and store it neatly with the seat.

Step 4: How to locate the governor spring in a golf cart.

• Step 5: Locate the largest cable connecting to the accelerator pedal. Follow this cable, and you'll find a small spring wrapped around a metal rod—this is the governor spring .

• Step 6: This part is held in place by two screws: one small and one large.

• Additional information: The area you are observing is also the carburetor of a golf cart.

Step 5: Adjust the governor spring to safely increase the speed of the golf cart.

• Step 7: Loosen the small screw slightly, then tighten the large screw.
  → Note: The large screw determines the spring tension – the tighter it is tightened, the faster the vehicle goes.

• Step 8: Tighten slowly, about 1/4 turn at a time, to avoid overloading the motor.

• Warning: If tightened too quickly or too forcefully, the motor may operate erratically, jerk, or be damaged.

Step 6: Secure the spring and check the vehicle speed after adjustment.

• Step 9: After tightening the large screw to increase speed, tighten the small screw again to keep the spring fixed and prevent it from slipping.

• Step 10: Test drive the car to check its speed.
  → If you find the speed is appropriate, keep it as is and ensure both screws are tightened securely.

• Notes when running the test:

  • If the car makes strange noises, jerks, or knocks, you may have overtightened the screws.

  • Then, slightly loosen the large bolt to reduce the pressure on the engine.

Step 7: Reassemble the bike and get ready to experience a new level of speed.

• Step 11: Reattach the black plastic cover to the engine as it was originally.

• Step 12: Reassemble the seat and other parts in their correct positions.

• Completed: Now you can take a test drive and enjoy the feeling of going faster!

Step 8: Important notes before accelerating the golf cart

• Impact on the engine: Increasing the top speed by adjusting the governor spring forces the engine to work harder, leading to increased wear and tear. You may need to perform maintenance, repairs, or replace parts sooner than usual.

• Legal issues:

  • If a vehicle exceeds 19 mph (approximately 30 km/h), it will be considered a motor vehicle under the law.

  • At that point, you'll need to buckle up, undergo a technical inspection, and possibly comply with additional traffic safety regulations.

• Advice: Although adjusting the speed isn't overly complicated, you should still carefully consider the vehicle's durability and legal regulations before proceeding.

Part 2: How to adjust a golf cart engine without a governor spring?

Step 1: How to open the seat and plastic cover to adjust the golf cart engine.

• Step 1: Remove the seat and the plastic engine cover.
  Some cars require removing screws, but many modern models have seats that can be easily removed without tools.

• Step 2: Reveal the engine so you can begin making adjustments.

• Note: If your bike doesn't have a central governor spring, there are still ways to make it go a little faster with other adjustments.

Step 2: Learn and adjust the clutch pedal to increase the golf cart's speed.

• Identify the clutch pedal:
  → This pedal is usually located next to the gas pedal, or it might be a lever near your knee.
  → Used for shifting gears, for example, reversing or changing speed.

• The effects of the stick:
  → You can adjust the clutch to deliver more fuel to the engine, allowing the car to go faster.

Step 3: Adjust the cable on the clutch side to increase fuel to the engine.

• Locate the small metal rod: It's located right next to the clutch pedal, attached to a cable.

• The significance of the cable: The length of this cable determines the amount of fuel delivered to the engine.

• Important note:
  → When the amount of fuel increases, the engine will work harder.
  → Try making small adjustments one at a time and pay attention to any unusual noises or engine jerking to avoid damaging the engine.

Step 4: Adjust the cable to increase or decrease the speed of the golf cart.

• Speed ​​increase: Loosen the screw securing the cable to the metal bar, and you'll see the cable extend slightly. This allows the vehicle to go faster.

• Slowing down: Tighten the screw to shorten the cable, causing the vehicle to slow down.

Step 5: Note on adjusting the governor on modern golf carts.

• The governor cannot be adjusted without seeing the governor cable or spring.
  This problem is common in modern electric golf carts.

• Some manufacturers, like EZ Go, hide the governor within the spark plug ignition system.
  Adjusting at this position is very complicated and can easily damage the engine.

• Recommendation:
  → These types of vehicles should be handled by experienced technicians; you should not attempt to adjust them yourself.
