MOOSUN MECHANICAL AND CENTRIFUGAL CLUTCHES act as inexpensive transmissions. They are designed to allow for safe, no-load, quiet starting of power equipment. Once engaged, MOOSUN clutches help reduce vibration, utilize peak torque for more efficient engine performance, and provide overload protection for operator and equipment safety. Centrifugal clutches are by far the most common and affordable clutches for go-karts.For proven quality centrifugal clutches, MOOSUN is your answer.
You Will Get:
- 1 x 12 teeth centrifugal clutch
- 1x #40/41/420 chain
Set Screws NOT Included. Mounts onto crankshaft using bolt and washer on the end of the crankshaft. (Clutch does not need set screws as long as the end of the crankshaft is threaded to accept a bolt. Most go kart clutches are held onto the shaft with a bolt and larger washer. Extra washers if needed are used on the crankshaft to space clutch.)
Specifications:
Centrifugal clutch designed to be used on one wheel karts with rear tires no larger than 15" tall, and engines 2hp-7hp. Larger tires and live axles recommend using Torque-converter ( ASIN:B07T1KRS4V)

That means response … based upon your standards, not somebody else's.
Is a Go-Kart Torque Converter or Clutch Better?
What's better, a torque converter or a clutch? The answer really depends on its intended use, which is ultimately related to your driving habit. As torque converters handle low torque ranges more easily, they’re most commonly used on off-road go-karts. They perform better at lower speeds and are ideal for stop-and-go situations. This is because off-road go-karts are sometimes required to climb uneven terrain at lower speeds.
Clutches on the other hand are snappier and perform better at high speeds. They’re designed to be constantly engaged, which makes them ideal for racing go-karts. High performance go-karts even have a multi-disc clutch to cater for various torque ranges. So, if you’re comparing a go-kart torque converter vs a clutch, you should make a choice depending on what you’re using it for.
Habits That Can Ruin A Clutch - Keep Your Machine Safe
- Driving too slowly: A clutch starts to engage around 2,000 rpm and will lock up around 2,600 rpm.
- Short stop and go driving: The longer you drive at full throttle the better off it is for the clutch, because it gives it a chance to cool off before the next engagement.
- Driving with the foot on the brake: This is a problem with new drivers that are unsure of themselves.
- Changing the size of the tires: Putting on tires that are larger than what came with the kart will result in clutch problems.No larger than 15" tall.
- Weight: A centrifugal clutch is designed to be able to move a certain amount of weight.
- Gear ratio: The sprocket on the engine and the one on the rear axle should have a ratio close to 1:6.(10 tooth = 60 rear sprocket)
Warm Tips:
About the Clutch Smoke:
The clutch weight rpm just isn’t excessive sufficient. The engine not being highly effective sufficient sometimes is the result of a mismatch in ratios to the rear-drive wheels. So the true motive is that the ratio just isn’t steep sufficient, and subsequently, the engine smokes the clutch.
The treatment for the primary clutch smoking drawback is to change the driveline in order that the general ratio is steeper. The easy technique is to extend the rear sprocket diameter.
So the clutch engagement rpm must be taken under consideration in any other case the clutch will smoke on the secondary jackshaft mounting place.
How Do You Install A New Clutch on A Go Kart?
ASSEMBLY INSTRUCTIONS:
Step 1: Remove outer drive cover. Loosen nuts on bottom of engine mounting plate allowing engine to slide back,loosening drive chain.
Step 2: Remove drive chain from drive wheel sprocket(axle sprocket). Remove bolt and washers from end of engine crankshaft while noting location of spacers and washers for installing new clutch.
Step 3: Remove clutch from engine crankshaft. Install new clutch by aligning key inbore of clutch with keyway in engine crankshaft. Slide clutch onto shaft.
Step 4: Reinstall bolt and washers that hold clutch on crankshaft. Tightenbolt.
Step 5: Reinstall drive chain on clutch and drive wheel sprocket(axlesprocket).
Step 6: Slide engine forward to tighten chain. Chain should have approximately 1/4" deflection when properly tensioned.
Step 7: Tighten nuts on bottom of engine mounting plate.
Reinstall outer drive cover.
WARNING! Guards must be inplace to protect rider(s) from rotating parts.

The exact thing we have been looking for for the past year. Fits our Manco Magnum Express go cart. Material seems of good quality. And chain size is PERFECT.

So the chain came in great condition and the clutch but it wasn’t fully oiled so that’s the only complaint that I have but I would recommend for a cheap replacement. Also it would be nice if they listed how long the chain it

Es bueno el producto, si lo quieren para algo diferente a un go kart busquen otras opciones ya qué yo lo utilice para un motocultor casero y más bien siento q es para correr.

I swapped my coleman cc100x with a 212, this chain that came with it was way to big, moving the engine and adjusting that slider won’t do anything so I just kept the stock chain and used this clutch. Wish they came with a bolt to hold the clutch down tho, it came with these 2 things which are useless have no idea what their for. You can see them in the pictures. It looks like a bolt but it’s just a tiny metal piece that dosent go anywhere

Lo instale en un motor de 7hp tal vez la durabilidad sea menot que con un motor de menos potencia pero se siente buen producto sin embargo mi cigueñal es de 20mm y tuve que llevarlo al torno para ajustar.funciona muy bien pero hay que estar lubricando para evitar que el calor hinche metales y abra pastas en ralenti, fuera de eso estoy satisfecho con la calidad y la cadena también se siente de buena calidad aparte de eso llegó muy rapido
