BUHNSS Aluminum Flywheel Kit for Predator 212cc 224cc Non-Hemi — 22lb Spring, 10k RPM, Integrated Fan

BUHNSS Aluminum Flywheel 10krpm 22lb Spring Kit is an upgraded, die-cast flywheel and spring package designed to raise engine RPM, improve cooling, and provide quicker throttle response for Predator and compatible clone 196–224cc non-hemi motors.

This complete kit replaces the factory cast-iron flywheel on non-hemi small engines and adds a 22lb spring set plus a spark plug for immediate installation. The unit is engineered from die-cast aluminum with integrated fan blades, dynamic balancing, and an 8° built-in timing advance to move ignition toward 32° TDC. It’s aimed at users who want higher rotational speed, reduced rotating mass, and improved heat dissipation without extensive machine work.

How does this flywheel increase engine performance?

The lighter aluminum construction cuts rotating mass so the engine revs faster and reaches higher RPM more readily. The built-in timing advance shifts ignition earlier, extracting more usable power at high revs while the balanced design keeps vibration in check.

• Die-cast aluminum reduces inertia for quicker rev-up.
• 8° built-in advance moves ignition toward 32° TDC for improved top-end response.
• Dynamic balancing reduces vibration at elevated RPM.
• Threaded design secures reliably for high-speed rotation.

Will it fit my Predator or clone engine and how easy is installation?

The flywheel is made for Predator 160cc–224cc non-hemi engines and common clone motors such as Honda GX200 replacements and BSP/Tilly style blocks. It includes a puller hole feature and comes with a spark plug and 22lb spring kit so you can swap parts with basic hand tools; a puller tool is recommended for safe removal of the old flywheel.

• Compatible with Predator 160/196/212/224cc and many 196cc clone engines.
• Includes spark plug and 22lb spring kit for one-stop replacement.
• Puller hole allows use of standard flywheel puller for removal.
• Threaded mounting and single-mold casting simplify fitment and fastening.

How does the flywheel help engine cooling and durability?

Integrated fan blades are cast into the flywheel to increase airflow over the cylinder head and fins, helping lower operating temperatures during sustained high-RPM use. Multiple blades and careful casting reduce hotspots while the dynamic balancing process minimizes stress on bearings and seals.

• Integrated fan blades boost cylinder head airflow for better cooling.
• Multiple blades and single-mold casting limit vibration and hot spots.
• Dynamic balance treatment reduces bearing loads at high RPM.

What do the included 22lb springs and spark plug add?

The 22lb spring kit is selected to improve clutch engagement characteristics at higher RPMs and can deliver extra performance above roughly 7,000 RPM. The included spark plug gives you one less part to buy during installation and is matched to the kit’s higher-speed intent.

• 22lb springs improve clutch engagement and high-RPM performance.
• Spring length and rate may vary slightly between sets for intended tolerance.
• Supplied spark plug allows immediate start-up after installation.

Who is this for? This BUHNSS kit is aimed at hobbyists, kart racers, small-machinery tuners, and anyone running Predator or compatible clone non-hemi engines who wants a reliable high-RPM upgrade without custom machining. It’s best suited to users comfortable with basic engine disassembly and who accept the trade-offs of higher RPM operation (increased wear potential and the need for correct fastening and balancing). If you need a drop-in lightweight flywheel that also improves cooling and advances ignition timing, this kit offers a practical, install-ready option.
