Buying Guide: Selecting the Best Clutch For Your Predator Engine

When looking for a clutch for your Predator 212 engine, it’s important that you consider various aspects such as the compatibility, bore diameter, chain size, sprocket teeth and engagement range. This section aims to provide you with as much relevant information as possible, to help you make an informed purchase decision. 

Compatibility

I’ve created a table with the three most common centrifugal clutches that are available on the market. The clutches that are compatible with a Predator 212 engine have different bore diameters and chain size compatibility.

Wrong bore size

As you can see, the Predator 212cc engine has two compatible centrifugal clutch that can be used: the 10T & 3/4″ Clutch and the 12T & 3/4″ Clutch. However, I highly recommend the 10T & 3/4″ Clutch, as it’s compatible with larger and more heavy-duty chains. 

Let’s explore the bore diameter and recommended chain size in a little more detail. 

Bore Diameter

One of the most important things that you’ll need to take note of is the clutch bore diameter, as this has to be compatible with your Predator 212 engine. 

predator 212 bore shaft diameter

In the image above, you’ll see that the bore of the clutch needs to be 3/4″ in order for it to be compatible with the Predator 212 engine. This is because the shaft diameter (diameter of the engine’s crankshaft) is also 3/4″ and the go-kart clutch slides on top of the crankshaft.

This also means that clutches which have other bore diameter sizes such as 5/8″ are not compatible with your Predator engine. Therefore, it’s important to look at the bore diameter carefully before deciding which clutch to purchase.

Chain Size

When looking at the Predator 212 go-kart clutch, you’ll have the options of a 3/4″ bore with a 10-tooth sprocket or a 12-tooth sprocket. The important thing to understand here a 10-tooth sprocket clutch supports #40, #41 and #420 chain, whereas the 12-tooth sprocket clutch supports a #35 chain. 

predator engine clutch chain size

As you can see from the illustration above the pitch of a #35 chain is relatively small at 3/8″. I don’t recommend #35 chains, although it’s possible to use them on go-karts. However, chances are that they may break under a too heavy load. 

Instead, I would recommend that you opt for a clutch that is has 10 sprockets and supports a #40/41/420 chain. These chains have a 1/2″ pitch and are also larger in size. Therefore, you’ll be able to pick either a #40, #41 or #420 chain, which is more durable. 

If you need more information on the various aspects of chain sizes, feel free to check out the go-kart chain size chart that I created. 

Sprocket Teeth

As you’ll need to opt for a clutch with a 3/4″ bore diameter, you’ll have the choice of a 10-sprocket or 12-sprocket version. There are two main differences between both types of Predator clutches. 

The 10-sprocket clutch is compatible with a #40/41/420 chain, which I highly recommend, while the 12-sprocket clutch is only compatible with a #35 chain. 

Engagement Speed

You will also see that each clutch has a specific engagement range. The engagement range of a go-kart clutch the speed at which it engages. When the crankshaft of the Predator 212 engine reaches that speed (rpm), the friction material of the clutch makes contact with the outer drum. 

Once it makes contact, it engages and enables the clutch to spin with the crankshaft, in order to transfer the rotational power from the engine to the rear axle, and ultimately to the wheels. 

Most go-kart clutches that are compatible with Predator 212 engines have an engagement range of 2,300 ± 300 rpm, meaning somewhere between 2,000 and 2,600 rpm. 

Engine Output

The output engine of a go-kart determines its power and ultimately how fast your go-kart is. The Predator 212 engine has an output of 6.5 hp. Most commercially available centrifugal clutches are suitable for up to 8 hp, which make them suitable for the Predator 212 engine. 

If you have installed any type of Predator engine mods or upgraded any components that increase the overall output of your engine above 8 hp, then I recommend that you either opt for a heavy-duty clutch or a racing clutch. 

This is because an overpowered engine may cause excessive wear on a regular clutch causing it to fail over the long term. 

Tire Size

You’ll also notice that each clutch will usually have a recommended maximum tire size, which is about 15” or less. Larger tires aren’t compatible with these types of clutches and it’s best to ensure that your tire size doesn’t exceed this diameter limit. 

Frequently Asked Questions

If you’re looking for the best go-kart clutch for your Predator 212 engine and still have some questions, then you are at the right place. I’ve compiled a list of the most frequently asked questions on this topic. If you have any questions that aren’t on this list, feel free to get in touch and I’ll be happy to address them. 

What Type of Clutch is Best For a Predator 212 Engine

There are various types of go-kart clutches that work differently, but have the same purpose and function. 

  • Centrifugal Clutches
  • Hydraulic Clutches
  • Electromagnetic Clutches

The most commonly used clutch is a centrifugal clutch, which is also featured in the review section. I recommend centrifugal clutches over any other type, as they are a lot more affordable and require less maintenance than electromagnetic and hydraulic clutches. 

Is a Clutch or a Torque Converter Better For a Predator Engine?

It really depends on what type of go-kart you have. If you have a predator engine installed on your off-road go-kart and you do a lot of off-road racing, then a torque converter may be preferred. 

On the other hand, a go-kart clutch is more common on homemade or racing go-karts. Check out my guide on go-kart clutches vs torque converters for more information on this topic. 

My goal with this site is to share valuable go-kart racing information through guides, articles, reviews, track details and more.
