FDJ's 3/4" centrifugal clutch with a 10-tooth sprocket is a ready-to-install replacement designed to fit 212cc Predator and many 2–6.5HP small engines, delivering smooth power engagement for mini bikes and go-karts.

If you maintain or build small-engine projects like mini bikes, go-karts, or DIY off-road rigs, the right clutch makes assembly and operation far simpler. This FDJ clutch is built around a 3/4" bore with a 3/16" keyway and ships with a 5/16-24 bolt and washer kit so you can mount it directly to compatible crankshafts. It supports a heavy-duty 10-tooth sprocket for reliable chain drive compatibility and recommends simple maintenance to maximize lifespan.

How does this clutch fit my Predator 212cc or similar engine?

This clutch was made to accept a 3/4" shaft and the factory 3/16" keyway, so it bolts straight onto many popular small engines without modification. It includes the mounting bolt and washer required for secure installation, streamlining replacement or upgrades.

• 3/4" bore with built-in 3/16" keyway for direct crankshaft fit.
• Included 5/16-24 mounting bolt and washer for immediate installation.
• Compatible with 212cc Predator and many 2–6.5HP engines from major brands.

What drive chains and sprocket sizes work with this unit?

The clutch is fitted with a robust 10-tooth sprocket engineered for smooth engagement around 2300 RPM. It is compatible with common small-engine chain sizes so you can choose the chain and rear sprocket to match your vehicle's gearing needs.

• 10-tooth sprocket for predictable engagement and load distribution.
• Works with #40, #41 and #420 drive chains for flexible drivetrain choices.
• Ideal for rear tires up to about 15" on mini bikes and many go-karts.

What routine care keeps the clutch reliable and quiet?

Longevity depends mainly on correct lubrication and avoiding contaminants. The internal bronze bushing needs periodic lubrication, but ventilation holes must remain free of oil to prevent belt or chain slippage and engagement problems.

• Lubricate the bronze bushing approximately every 4 hours of heavy use.
• Do not add oil into the ventilation holes to avoid slippage.
• Inspect sprocket teeth and chain compatibility during routine maintenance.

Will this clutch work for custom builds or off-road models like Coleman or Baja?

Yes — the clutch suits many mini bike and go-kart platforms, including well-known off-road models and custom DIY frames. It offers a heavy-duty construction and common interface dimensions, making it a practical upgrade or repair part for a wide range of projects.

• Engineered for Coleman CT200U, Baja MB165/MB200 and similar models.
• Works well for custom karts and mini bikes using 3/4" shafts and 3/16" keyways.
• Designed for rear tires up to ~15" and standard small-engine power ranges.

Who is this for: Builders, hobbyists, and mechanics who repair or assemble small-engine vehicles and want a straightforward, durable clutch replacement. If you run a 212cc Predator or a 2–6.5HP engine with a 3/4" shaft, and you prefer a clutch that arrives ready to mount with bolt and washer hardware, this FDJ unit is a practical, serviceable choice. It suits performance-minded DIYers who value a heavy-duty 10-tooth sprocket and straightforward maintenance guidance to keep drivetrain noise and wear under control.
