Vashly Centrifugal Clutch for Go-Kart 11T 5/8" Bore — #35 Chain, Iron, Fits Predator 212

Vashly's 11-tooth centrifugal clutch with a 5/8" bore is a durable replacement designed to transfer power to a #35 chain on small engines for go-karts, minibikes, and fun karts.

If you need a compact, reliable centrifugal clutch to connect a single-wheel drive setup to a 2–6.5 HP small engine, this unit offers a balance of strength and heat-dissipation in a lightweight iron build. It fits common horizontal shaft engines like the Predator 212 and many 97–196cc motors used in DIY karts, minibikes, garden tractors and generators. The package includes mounting hardware so you can install it immediately, but remember chain and sprockets are not included.

How does this clutch engage and protect my engine during use?

The centrifugal design automatically engages as engine RPM increases, letting the kart accelerate smoothly without manual shifting. Its iron construction provides good thermal conductivity to help dissipate heat under load, while the internal mechanism slips at low RPM to reduce stalling and shock loads.

• Automatic engagement with rising RPM for smooth takeoff
• Iron body for faster heat dissipation and wear resistance
• Designed to reduce drivetrain shock during starts

Will this 5/8" bore, 11-tooth clutch fit my engine and chain setup?

The clutch has a 5/8-inch bore and an 11-tooth sprocket sized for #35 chain, making it compatible with many small horizontal-shaft engines and standard mini kart drivetrains. It commonly fits 2 to 6.5 HP engines, including models like the Predator 212 and popular 97cc–196cc engines, but always verify crankshaft diameter and chain size before ordering.

• 5/8" bore — check your engine crankshaft diameter first
• 11-tooth sprocket — intended for #35 chain systems
• Compatible with 2–6.5 HP small engines (minibike, go-kart, generators)

How easy is installation, and what hardware is included?

Installation is straightforward and reversible: the clutch mounts to the crankshaft using the supplied bolts and washers and can be oriented inward or outward. Vashly includes two clutch bolts, two washers, and two screw wrenches so you have the basic hardware to secure the clutch immediately after purchase.

• Mounts onto crankshaft using included bolts and washers
• Bi-directional mounting — fits inward or outward orientations
• Metric property class 8.8 bolt quality included for secure fit

What materials and performance can I expect from this clutch?

Constructed from quality iron, this centrifugal clutch balances low weight with durability, delivering dependable torque transfer while tolerating typical karting stresses. Its construction aims for long service life and consistent performance in recreational and light work applications, though regular inspection and proper chain tension keep it working best.

• Iron construction for strength and heat management
• Designed for maximum torque transfer to a #35 chain
• Recommended for tires up to about 15" tall in single-wheel drive setups

Who is this for: This Vashly clutch is made for DIY builders, hobbyists, and repairers of small recreational vehicles who need a reliable centrifugal clutch for a single-wheel drive system. It suits users with 2–6.5 HP horizontal engines (including Predator-style motors) who want an off-the-shelf replacement that comes with mounting hardware and fits #35 chain drivetrains. If you are unsure about fitment, measure your crankshaft bore and confirm sprocket compatibility before purchasing, or contact Vashly for guidance.
