FDJ Centrifugal Clutch & #35 Chain Kit — 3/4" Bore, 12-Tooth Sprocket, 5 ft Chain for 2–7 HP Engines

FDJ 3/4" centrifugal clutch with 12 teeth and a 5-foot #35 chain kit is a ready-to-install drive solution for small engines used in go karts, mini bikes, and fun karts.

This clutch-and-chain bundle is built to pair with common 2–7 HP small engines — including many Honda and 212cc Predator models — and supplies the mounting hardware and connecting links you need to get a rear sprocket driven reliably. It combines a compact 3/4" bore centrifugal clutch with a matched length of #35 chain and the bolts and tools required for assembly, so you can replace or upgrade a worn drive system quickly.

How does this clutch fit my engine and kart?

The clutch has a 3/4" bore designed to slide over standard crankshafts used on many small engines. It is compatible with a range of 2–6.5 HP Honda engines and 2–7 HP 212cc Predator engines, and adapts to typical go kart and mini bike drivetrains with a 12-tooth sprocket.

• 3/4" bore for common small-engine crankshafts
• 12-tooth sprocket matches standard #35 drivetrains
• Works with Honda GC/GX series and Predator 212cc engines

What materials and construction should I expect?

The clutch housing is machined from iron and finished with chrome plating for corrosion resistance and improved heat dispersion. The design emphasizes durability and torsional strength for repeated engagement and load cycles found in recreational vehicles.

• Chrome-plated iron body resists wear and surface rust
• Engineered for faster heat dissipation under load
• Balanced to reduce vibration and extend component life

What comes in the kit and how difficult is installation?

This package gives you the clutch, a five-foot length of #35 chain, two connecting links, a clutch mounting bolt and washer set, additional screws, and an Allen wrench. Installation is straightforward for anyone comfortable with small engine work: mount the clutch to the crankshaft, tension the chain to the rear sprocket, and secure fasteners to the specified torque.

• Complete hardware kit included to simplify installation
• Chain length ideal for most compact kart layouts; can be shortened
• Basic hand tools and simple mechanical skills required

How will this kit affect performance and maintenance?

When correctly installed, the centrifugal action engages the driven sprocket smoothly as engine RPM increases, providing predictable drive engagement for recreational riding. Routine checks of chain tension and fastener tightness will maintain dependable operation and prolong component life.

• Smoother engagement reduces drivetrain shock on acceleration
• Regular lubrication and tension checks prevent premature wear
• Replacement parts are standard #35 components for easy sourcing

Who is this for: This FDJ clutch-and-chain kit suits hobbyists, small-engine mechanics, and DIY builders who need a compact, durable centrifugal clutch compatible with common 2–7 HP engines. It's ideal for restoring or upgrading go karts, mini bikes (MB165/MB200), Baja-style recreational vehicles, and similar small drivetrains where a 3/4" bore and #35 chain are the correct fit.
