Vashly 12T Centrifugal Clutch for Go-Kart & Minibike 3/4" Bore #35 Chain Fits Predator 212 / Honda GX160 GX200

Vashly's 12-tooth centrifugal clutch is a durable 3/4" bore clutch designed to drive #35 chain systems on go-karts, minibikes and small-engine projects.

This compact centrifugal clutch engages automatically with engine speed, converting RPM into smooth, reliable power transfer without a manual lever. Built for common small-engine platforms—Predator 212, Honda GX160/GX200 and many clone motors—this 12T unit is intended for hobby and light-duty work where a simple, bolt-on clutch is needed. The clutch ships with mounting hardware and fits shafts with a 3/16" keyway.

How does this clutch fit my engine and drivetrain?

The Vashly clutch is made for a 3/4" diameter crank shaft with a 3/16" keyway and mates to #35 roller chain sprockets (12-tooth). It is compatible with many popular small engines including Honda GX120–GX200, Predator 212, and common 5.5–6.5 HP clone motors. Before ordering, confirm shaft diameter and keyway size to ensure correct fit.

• 3/4" bore with 3/16" keyway — standard on many small engines
• 12 tooth (12T) sprocket for #35 chain systems
• Commonly fits GX120/GX140/GX160/GX200 and Predator 212/196cc
• Includes bolts, washers and Allen wrench for installation

What performance and construction features should I expect?

This clutch is machined from iron for strength, wear resistance and better heat dissipation under frequent engagement. Its centrifugal design engages progressively as RPM rises, reducing shock on the drivetrain and making it suitable for karts, minibikes and fun karts. It’s intended for light- to moderate-duty applications rather than heavy industrial loads.

• Iron housing for durability and thermal stability
• Centrifugal engagement for smooth starts and stops
• Designed for maximum torque transfer within its size class
• Fast heat dissipation to handle repeated use in hobby riding

How do I install and maintain the Vashly 12T clutch?

Installation is straightforward: mount onto a 3/4" shaft with the 3/16" key in place, torque the supplied bolts and align the clutch sprocket with your driven sprocket. Periodic inspection of bolts, keyway fit and shoe condition will keep the unit working reliably. Replace worn shoes or hardware to maintain safe operation.

• Use the supplied bolts, washers and Allen wrench for correct fastening
• Ensure sprocket alignment to avoid chain wear and noise
• Inspect for shoe wear and clean debris after heavy use
• Re-torque mounting bolts after initial run-in and periodically

Who is this for? If you build or repair go-karts, minibikes, fun karts or small mechanical projects using common small engines, and you need a rugged, easy-to-fit centrifugal clutch for a #35 chain drive, the Vashly 12T 3/4" bore clutch is designed for that role. It suits hobbyists and DIY mechanics who want a reliable, bolt-on clutch compatible with many GX-series and clone engines. Confirm shaft diameter and keyway before purchase to ensure compatibility.
