How to Do Predator 212 Engine Governor Adjustment

Governor adjustments are one of the many Predator 212 modifications you can do in go-karting. You can do Predator 212 governor adjustment by adjusting the governor spring or removing the governor entirely.

Method 1: Adjusting The Governor Spring

This method is the easiest way for achieving higher RPM on a Predator 212 engine.

Materials Needed

  • An 8 mm socket
  • A 10 mm socket
  • A pair of needle pliers
  • A locking pillar

Working Process

To adjust the governor spring, follow these steps:

  1. Pinch off the fuel line using a locking pillar to prevent the fuel from coming out.
  2. Use 8mm and 10mm sockets to detach the Gas Tank.
  3. Remove the gas tank to expose the governor mechanism. 
  4. Locate the governor spring as shown here in this picture:

  1. Remove the governor spring. 
  2. Measure the length of the spring.
  3. Slightly reduce the length of the spring using a pair of needle pliers.
  4. Reinstall the governor spring.

Your governor adjustment is now complete. The Predator 212 engine can now achieve higher RPM than before. 

If you wish to get more power out of the Predator 212 engine, you may also want to consider upgrading the Predator 420 carb.

Method 2: Removing The Predator 212 Engine Governor Altogether

Follow this method only if you want to completely remove the RPM limitation of your Predator 212 engine.

Materials Needed

  • An M6 Socket
  • An Impact Wrench (for 10mm bolts)
  • A bowl for collecting oil
  • A needle plier

Working Process

  1. Pinch the clap on the fuel line of the Predator 212.
  2. Disconnect the fuel lines and detach the drive chain.
  3. Remove the mounting bolts that hold the engine to the go-kart chassis
  4. Place the engine on a workbench. 
  5. Place a bowl below the engine to catch the draining oil.
  6. Locate the short 10mm at the lower part of the engine that is marked in red:

  1. Use an appropriately sized socket to loosen and remove the bolt, allowing the oil to drain completely. You can lift the other end of the engine slightly to ensure all the oil is drained.
  2. Once the oil has fully drained out, securely screw in the oil plug.
  3. Take out the transmission system depending on the type of system:

For a Torque Converter:

Take off the crankshaft bolt that is connected to the driver pulley. 

Then proceed to take out the four bolts securing torque converter’ back plate to the predator 212.

For a Clutch:

Take off the crankshaft bolt. Then remove the clutch from the crankshaft and the key.

  1. Keep the engine in its current position. The side cover of the engine and its crankshaft should be facing toward you.
  2. Locate the six 10 mm bolts (M6) that is responsible for holding the engine cover against the body of the engine. Remove the six bolts from the engine cover using an M6 socket.
  3. Once all the bolts are removed, flip the engine over, so the crankshaft points upward.
  4. Carefully insert a thin and sharp object in between the Predator engine and the side plate to get the engine cover off. Alternatively, you can use a long tool to leverage against the oil intake for easier removal.

Tip: Take caution around the front dipstick location to prevent breaking the rubber gasket that separates the engine from the cover. If the gasket remains attached to the cover after removal, leave it. It will be needed again after reassembly.

  1. Once the cover is off, simply set it aside for now. The engine is now ready for further maintenance or inspection.
  2. Locate the governor gear that is attached to the governor arm.
  3. Find the 10 mm bolt that is situated on the top of the exterior of the Predator 212 engine that attaches the governor arm. Use the 10 mm socket to remove the nut. Then remove the governor arm
  4. Start by removing the lock pin and the governor shaft. These components might be held in place by clips or fasteners, so carefully disengage them to free the governor shaft.
  5. Once the lock pin and governor shaft are removed, proceed to take out the clip that secures the governor gear in place. After removing the clip, you can now remove the governor gear itself. Gently pull it out from its location.
  6. Lastly, locate and remove the washer positioned underneath the governor gear. Carefully position the side cover over the Predator 212 engine.
  7. Screw back on the bolts to secure the engine cover to the engine. Lightly tighten the bolts first. Afterward, tighten them fully. 
  8. With the side cover securely in place, you can now proceed to reinstall the transmission, and the chain. Then mount the engine back on its original position on the go-kart.
  9. Finally, take your kart for a test drive to ensure everything is functioning correctly.

Your Predator 212 governor has now been removed.

Is Predator 212 Governor Adjustment Risky?

Yes, Predator 212 governor adjustment can be risky, but only if you exceed 5,000 RPM. 

The internal parts of the Predator 212 can withstand up to this speed, even though they are rated for 3,600 RPM. 

So, if you are adjusting or removing the governor of your Predator 212, keep the speed below 5,000 RPM by maintaining the throttle. You may also find the Predator 212 sputtering at full throttle

If you need a more powerful engine, why not compare between the Predator 301 and 212 cc instead and pick the best!

This will prevent the engine from damage. You can also replace the flywheel with a billet flywheel to reduce the risk of the flywheel coming apart.

Frequently Asked Questions (FAQs):

How does an engine governor work?

An engine governor employs gears and flyweights within the crankcase to detect variations in the load. The governor then regulates the throttle accordingly, enabling precise control of the engine’s speed.

What is the use of a go-kart?

Go-karts are commonly used for dirt, off-road, or recreational purposes. Then can be used for both racing and non-racing events. Go-kart racing events are often held in different places.

How fast can a go-kart go?

A go-kart can go as fast as 250 mph. Go-karts with a higher cc rating blend more air with gasoline, resulting in higher speeds. For instance, a 50 cc kart can reach speeds of up to 35 mph, while a 125 cc kart can achieve 70 to 80 mph. The fastest go-karts, with a 250 cc engine, can reach incredible speeds of up to 150 mph


So, now you know all there is to know about Predator 212 governor adjustment. Adjusting the governor of your engine can give you an edge in go-karting. I hope reading this article helped you adjust the governor of your Predator 212 easily.

That is all for today. Thank you for reading my article. Goodbye and Goodluck with your Predator 212 engine!
