BUHNSS Aluminium Flywheel for Predator 212cc/224cc Non-Hemi — 22lb Spring Kit, 8° Timing Advance

BUHNSS Aluminum Flywheel with 8° built-in timing advance and 22lb spring kit is a direct-replacement high-speed flywheel assembly designed for Predator 212cc/224cc non-hemi and compatible clone engines.

This kit combines a die-cast aluminum flywheel, a performance 22lb spring set, and a replacement spark plug to deliver improved rotational response, cooler running through integrated fan blades, and a built-in timing advance. Engineered for use with Predator 160–224cc and common clone engines such as GX200/196cc variants, the assembly includes a puller hole and has been dynamically balanced to reduce vibration at high RPMs.

Will this flywheel fit my engine model?

The BUHNSS flywheel is made for Predator 160cc–224cc non-hemi engines and many clones (including Honda GX200 and similar 196cc variants). Verify bolt pattern, shaft size and flywheel face dimensions before ordering to ensure compatibility.

• Compatible models: Predator 160cc/196cc/212cc/224cc non-hemi and many 196–200cc clones (GX200-style).
• Includes puller hole for easy removal with standard pullers.
• Confirm mounting bolt pattern and keyway match your crankshaft.

How does this kit affect engine performance and operation?

The lightweight aluminum construction reduces rotating mass and resistance, allowing the engine to accelerate more quickly and reach higher RPMs. Integrated fan blades aid cooling, while the 8° built-in timing advance shifts ignition timing closer to 32° TDC for altered combustion timing characteristics.

• Die-cast aluminum lowers inertia for faster rev response.
• Fan blade integration improves airflow over the cylinder head during operation.
• 8° advance built into the flywheel adjusts ignition timing to 32° TDC for expected timing behavior.
• Dynamic balancing treatment reduces vibration at high speeds.

What do the included springs and spark plug do?

The kit’s 22lb springs are intended to provide firmer engagement at high RPMs, which can help maintain engagement of the starter/recoil mechanism or clutch components where applicable. The supplied spark plug is for replacement convenience and proper firing after installation.

• 22lb springs tuned for stronger return/engagement above ~7000 RPM (length and rate may vary).
• Replacement spark plug included to ensure reliable ignition after installation.
• Springs and plug are packaged with the flywheel for a single upgrade service interval.

How difficult is installation and what tools are needed?

Installation is similar to replacing a standard flywheel: remove the old flywheel with a puller, install the BUHNSS flywheel aligned to the keyway, and torque mounting hardware to manufacturer specs. The flywheel includes a puller hole and a threaded hub for secure fastening.

• Tools: appropriate socket/torque wrench, flywheel puller, keyway alignment tool if needed.
• Threaded center design aids secure mounting and balanced rotation.
• Dynamic balance holes ensure smoother operation after installation.

Who is this for: This BUHNSS aluminum flywheel and 22lb spring kit is aimed at hobbyists, small-engine mechanics, and performance-minded owners of Predator-series and GX200-style clone engines who want faster rev response, improved cooling from integrated fan blades, and a simple bolt-on ignition timing advance. It is suitable for go-karts, mini-bikes, generators, and other equipment using compatible 160–224cc non-hemi engines—provided you confirm fitment and follow safe installation practices.
