As you may have already known that the Predator 212 and other small engines that go on the go-karts are not really designed for Go-Karts. They are designed for usage on water pumps, generators, pressure washers, etc. All such devices work great if your engine is maintained at the constant RPM near 3600 RPM, and that’s why such Go-kart engines like Predator 212 have a governor that preserves the rpm to 3600.

If you are making use of this motor on the minibike or Go-kart, then there’s no benefit of keeping your governor. Unless you desire to keep your go-karts a little slow on purpose (for kids), then do not take them out. The only thing it’ll do is, make your kart slow.

The predator 212 engine that has the governor will rev at 3600 RPM maximum; without the governor, it can rev up to 5000 RPM (with other stock parts). Since rpm is relative to speed, if the setup makes use of the same tires and gearing, the mini-bike or Go-kart will be 1.5x faster than before.

What Does Taking Out The Governor Actually Do?

Small engines make use of mechanical governors for limiting the speed by limiting the throttle opening when your engine gets to a certain rpm. If you glance inside the governor, it has an arm, some flyweights, and gear. The governor gear is actually connected with its crankshaft and moves with it.

When the governor gear moves, the flyweights face centrifugal force and fly out, pushing the white shaft up. This shaft pushes the arm of the governor up from the inside, which causes the governor’s arm to face a force on the outside half.

The governor’s arm has the spring that attaches to the carburetor throttle and provides speed control to your governor. When the spring is strained, the throttle will attempt to close; that’s why you can make your governor unusable by simply zipping the spring.

Risks Of Taking Out The Governor:

Taking out the governor will increase the max RPM of your engine, but the internal components of the Predator 212 are created for 3600 rpm. Usually, it is not a problem with just the governor elimination; the internal components can frequently withstand five thousand rpm without breaking apart (unless you go complete throttle for really long).

If you further append eighteen lb valve springs and other mods, then it’s highly suggested to get a billet rod and billet flywheel. You can also get them simply after taking out the governor for further safety.

Predator 212 Governor Removal:

Here’s the step-by-step guide on removing the governor of Predator 212; the process will be the same for the Honda GX200 or any other small Honda clone engine motors.

  • Unmount the engine from the kart.
  • Take out the transmission system and drain the oil.
  • Take out the fuel tank
  • Open the crankcase
  • Unscrew the Governor’s arm.
  • Use a hammer and screwdriver, and tap the snap ring of your governor
  • Remove all the components of the governor (comprising the washer under your governor gear)
  • Reassemble

Step#1: Unmount Your Engine

This one is understandable; you cannot remove your governor while it’s still mounted.

Predator 212  Unmount Your Engine

We’ll have to open up the engine to remove the governor, which can’t be accomplished while it is still mounted. However, you can bypass your governor without having to actually unmount your engine.

Step#2: Removing The Torque Converter/Clutch And Draining The Oil

Once your engine is out of your go-kart, you ought to take out the clutch or torque converter, whichever one you are making use of. It’s extremely simple to take out the clutch; you just remove the chain and bolt, and the whole clutch will come out.

For the torque converters, you can actually reverse the installation procedure for removing them. Once the Clutch/Torque Converter is taken out, you ought to drain out the oil from your engine. Just find the oil plug under its valve head and take out the plug.

Step#3: Removing Its Fuel Tank

Make use of eight mm and ten mm sockets for removing the Gas Tank. Make use of a screwdriver or the locking pillar for pinching off the fuel line to prevent the fuel from coming out.

Step#4: Removing Its Crankcase Cover

Before you take out the case cover, make certain the engine is in the sleeping position and not in the standing position, i.e., the crankshaft ought to be actually in the vertical state, facing up. With a ten mm socket, take out all the six bolts. Gently take out the cover. There’s a paper gasket under its cover; try not to tear that apart. If it does rip, you’ll need to get a new gasket.

Once its cover is out, what you will see is a camshaft, a crankshaft, gear, and a governor’s arm. We are attempting to take out the governor gear. But before we continue, make certain that you have the complete view of your governor by rotating its crankshaft.

Step#5: Moving The Governor Arm

Once you open its crankcase, you will be capable of seeing the Governor’s arm’s portion inside the crankcase. Our objective is to take out the governor gear, so we’ll have to move the arm’s inside portion to be capable of accessing the gear.

You have to loosen its governor arm from the crankcases outside with a ten mm socket. Once the outside and inside components are apart, you will be capable of moving the inside component of the governor’s arm easily.

Step#6: Remove The Governor Gear

Finally, now we can take out the governor. When you glance inside, you will initially see a white shaft that you can simply remove with the plier. You will then be capable of seeing a small lock clip at the bottom. Take a screwdriver and a hammer and tap on that clip to loosen it up. You can tap it with force or gently; it does not matter because you will be discarding that governor either way. Expanding the clip (lock ring) can be a long procedure, so be patient.

Step#7: Removing All The Components Of The Governor

Don’t leave any component behind; there’s a washer beneath your governor gear; make certain to remove it. It can be hard at times to remove the washer; utilize a magnetic tp screwdriver if you’ve got one. You are not finished just yet. There’s a little debris always leftover after the procedure; clean as much as possible. Any excess metals inside can cause damage to your crankshaft.

Step#8: Reassembling

And lastly, you can now reassemble all the components. Reconnect the governor arm’s outside portion to its inside portion and put back its crank cover. While assembling its linkage back, you’ll need to make use of an additional spring to provide the governor linkage with additional tension.

You can take out the arm completely and fill its hole, but the simplest thing to do is to let its governor arm on; it’s basically unusable without the other components of the governor. You can also change its throttle linkage after your governor is detached.

Zip Tie Process (Governor Bypass):

Preferably, you ought to take out the governor totally because you do not desire the governor gear actually to be rotating at high speeds. But, a few individuals don’t like the trouble of opening up the engine. For them, there’s another technique of bypassing the governor.

All you will require is a ten mm socket and a zip tie for removing the fuel tank. You can decide on not removing the tank, but taking out it will make the procedure simpler. The governor’s arm has two springs that come from it, one from the middle and another from the end. All you have to do is zip tie its spring that’s coming from the center of the governor’s arm.

The governor can actually control the speed by simply pulling that spring, so if you tie it, the spring will not expand, and your governor just becomes useless. It’s suggested to rather take out the governor because you don’t desire your governor gear to be spinning at the high RPM when it’s made to be working at 3600 RPM.
