TEANTECH Centrifugal Clutch 3/4" Bore 12T with #35 Chain — for 2–7HP Go Karts & Minibikes

TEANTECH's 3/4" bore, 12-tooth centrifugal clutch with a 4-foot #35 chain is a drop-in power-transmission kit designed to engage around 2300±300 RPM and drive go karts, minibikes, and small engine projects.

This kit combines a rugged centrifugal clutch and a matching #35 drive chain to transfer power from common 2–7 HP horizontal shaft engines to a sprocket or axle. Built to fit engines with a 3/4" shaft, it provides a straightforward way to add clutched engagement and reliable torque transfer without heavy modification. The clutch is widely compatible with popular small engines and aftermarket karts, making it a practical replacement or upgrade for hobbyists and light-duty builders.

What engines and vehicles will this clutch fit?

The TEANTECH clutch is engineered for engines with a 3/4" diameter shaft and works across a range of small horizontal-shaft motors. It lists direct compatibility with many Honda and commercial engine models and is also appropriate for similar Briggs & Stratton and Tecumseh powerplants with the same shaft size.

• Works with Honda GX160, GX200, GX140, GX120, GC160, GC190
• Compatible with Harbor Freight Greyhound 196cc and Predator 212cc
• Fits Briggs & Stratton and Tecumseh engines rated about 2–7 HP with 3/4" shafts
• Suitable for go karts, minibikes, and light fun-kart builds

How does the clutch engage and what performance should I expect?

This centrifugal clutch engages automatically as engine RPM rises, so there’s no manual linkage required. Engagement is centered around 2300±300 RPM, giving smooth takeoff and reliable disengagement at idle for easy starting and stopping.

• Rated engagement speed: approximately 2300±300 RPM
• 12-tooth sprocket design for standard #35 chain fitment
• Optimized for 2–7 HP engines delivering hobby-class torque
• Simple centrifugal action—no external controls needed

What comes in the kit and what should I check before buying?

The package includes the 12T clutch and a 4-foot length of #35 roller chain ready for installation. Before ordering, confirm your engine’s shaft diameter and measure clearances to ensure the clutch will seat correctly and align with your driven sprocket or axle.

• Included: 3/4" bore 12-tooth centrifugal clutch and 4 ft of #35 chain
• Check your engine shaft: must be 3/4" (0.75") to fit securely
• Confirm chain length and sprocket spacing for proper alignment
• Contact seller with fitment questions if unsure

How durable is the clutch and chain for regular use?

The clutch and chain are made for light-duty recreational use and maintenance-friendly operation. Proper installation, regular lubrication of the chain, and periodic inspection of wear surfaces will prolong service life and maintain dependable performance.

• Designed for hobby and light commercial applications up to ~7 HP
• Routine chain lubrication and tension checks recommended
• Inspect clutch shoes and sprocket teeth for wear periodically
• Replace chain or clutch when visible wear or elongation appears

Who is this for? Builders, DIYers, and small-vehicle enthusiasts who run 3/4" shaft engines and want a straightforward centrifugal clutch solution will find this TEANTECH kit practical. It’s ideal for go-kart and minibike projects, spare-part replacements, or upgrades on common Honda, Briggs & Stratton, Tecumseh, and similar horizontal-shaft engines—especially when you need automatic engagement near 2300 RPM and a matched #35 chain for reliable drive transfer.
