How do I turn off the speed limiter on my Go Kart

So you wanna juice up your go-kart, huh? Ditching the speed limiter is a pretty common move for folks who've been driving for a while and want a bit more thrill. But honestly, it's not a one-size-fits-all thing. It totally depends if you're running gas or electric, and messing with this stuff can get hairy, might trash your warranty, and even be dangerous. Let's walk through what you're actually dealing with, step by step, and the real risks.

What is the difference between a governor and a speed limiter?

People throw these terms around like they're the same thing, but they're not exactly. A governor is this mechanical or electronic thing that keeps the engine from revving too high—protecting it from blowing itself up. A speed limiter, though, is more electronic, cutting power or fuel when you hit a certain speed. On most karts you buy off the shelf, it's a governor, but the end goal is the same: keep you from going too fast.

How to disable the governor on a gas-powered go kart

For gas karts, you're usually getting physical with the governor mechanism. This is mostly for racing or off-road stuff, not your backyard joyride.

• Locate the governor arm: There's this little arm hooked to the carburetor throttle linkage, usually held in place by a spring. That's your target.
• Remove the governor gear (advanced): You'd have to crack open the engine crankcase for this. Honestly, it's risky as hell—one wrong move and your engine is toast. Only try this if you really know your way around an engine.
• Bypass with a zip tie (temporary): Some folks just zip-tie the governor arm in place. I really wouldn't. It lets the engine rev way beyond what it should, and that's asking for trouble.

Warning: Taking off the governor strips the engine of its main safety net. You're looking at potential catastrophic failure—connecting rods flying apart, debris shooting everywhere. Not pretty.

How to disable the speed limiter on an electric go kart

Electric karts are a different beast. They use a controller (Curtis or Sevcon are common) to limit speed, so it's all software, no wrenching.

• Identify the controller: Look for a black box with a bunch of wires going to the motor and battery. That's your brain.
• Access the programming port: Most have a serial or USB port hidden somewhere. You gotta find it.
• Use manufacturer software: You'll need specific software—like Curtis 1314 programming station—and a compatible cable. Then you tweak the "Max Speed" "RPM Limit" settings.
• Check for a "Speed Limiter" wire: Some karts, like Razor models, have a single wire loop. Cut it, and the limit's gone. It's that simple.

Warning: Crank up the speed on an electric kart, and the motor and controller can overheat. That's a fire risk or permanent damage. Not worth it if you're not careful.

What are the risks of disabling the speed limiter?

Look, this isn't just a free upgrade. There are real downsides.

Is it legal to remove the speed limiter?

It's a gray area. In the US, the CPSC regulates off-road vehicles. If your kart was certified as a "Youth Model" (top speed under 15 mph), modding it can make it illegal to sell or use in some areas. For racing karts on private tracks, it's usually fine, but the track might have its own rules. Check your local laws—seriously.

People Also Ask

Can I use a remote to turn off the speed limiter?

Nope, no universal remote for that. The limiter is built into the engine or controller physically or through software. Some high-end racing karts have telemetry, but that's for data, not remote disabling.

Will removing the speed limiter make my go kart faster?

Yeah, but how much depends on the kart. A 6.5 HP gas engine might jump from 15 mph to 25-30 mph. An electric 24V kart might go from 12 mph to 18 mph. The motor's power and gear ratio still set the ceiling.

How do I know if my go kart has a speed limiter?

Look for these clues:

• The kart hits a certain speed and feels like it "hits a wall" or cuts out.
• On gas karts, there's a spring-loaded arm on the carburetor that won't open fully.
• On electric karts, the manual mentions a "speed limit" or "training mode."
• There might be a "Parental Control" screw or wire loop on the frame.

Checklist: Before Disabling the Speed Limiter

• Have you identified the type of limiter (mechanical or electronic)?
• Have you upgraded the brakes? (Hydraulic brakes are recommended for speeds over 20 mph).
• Have you checked the tire rating? (Look for speed rating on tire sidewall).
• Do you have proper safety gear? (Helmet, gloves, racing suit).
• Is the kart only for use on private property?
• Have you consulted the manufacturer's service manual?
