EOPOAYI 212cc Aluminium Hemi Flywheel for Predator 212 (60363) — Precision-Balanced, Includes Valve Springs & Jet Kit

This precision-machined flywheel swaps into compatible small-block engines to help stabilize high RPM operation and support power delivery up to 10,000 rpm. Packaged with valve springs, a main-jet kit and a crankshaft key, the EOPOAYI assembly gives you the parts needed for a smooth installation and a more resilient powertrain. It is engineered to match OEM dimensions for straightforward fitment on specified Hemi-style 212cc platforms and several common clone engines.

Which engines and vehicles will this flywheel fit?

The EOPOAYI 212cc flywheel was made for Predator 212 Hemi (model 60363) applications and many 6.5HP GX160/GX200 style clones. It’s also compatible with various mini bikes, go-karts and small utility machines that use the same Hemi-style crank and bolt pattern. Confirm your engine model before ordering to avoid incompatibility with non-Hemi Predator variants or the Predator Ghost series.

• Compatible with Predator 212 Hemi 60363 and select 224cc Hemi variants
• Fits GX160/GX200 6.5HP clone engines and Tillotson-style 212cc designs
• Used on Coleman CT200U/CT200U-EX, BT200X, Baja MB165/MB200, Manco/Yerf Go-karts and similar machines
• Not compatible with non-Hemi Predator engines or Predator 212 Hemi Ghost

How does this flywheel affect engine performance and reliability?

Built from high-strength aluminum and steel components, the flywheel reduces unwanted vibration through precision balancing and supports higher RPM operation. That improved rotational stability helps the engine maintain smoother throttle response and consistent power under load. The included valve springs and jet components support tuning and reliability for spirited use.

• Precision-balanced to minimize vibration at elevated RPMs
• High-strength construction resists deformation under stress
• Supports smoother revving and more stable power delivery to the drivetrain
• Accessory parts (valve springs, jet kit) help with tuning and longevity

What comes in the package and why it matters?

The kit includes the aluminum hemi flywheel, two 26 lb valve springs, a main jet kit (emulsion tube plus three main jets .036, .037, .038) and a metal crankshaft key. These components let you perform a straightforward swap while adjusting fuel delivery and valve control for higher-performance operation. The included hardware reduces the need to source separate tuning parts after installation.

• 1x aluminum hemi flywheel matched to OEM specifications
• 2x 26 lb valve springs for improved valve control at high RPMs
• Main jet kit with emulsion tube and three jets for carb tuning options
• 1x metal crankshaft key for secure flywheel mounting

Is installation difficult and are modifications required?

EOPOAYI designed this flywheel to align with factory dimensions so most installs are bolt-in when used on compatible engines. Basic mechanical skills and common shop tools are usually sufficient; more involved engine work may require valve timing checks and carburetor tuning. Avoid forcing the flywheel onto incompatible crank tapers and verify fitment notes before starting.

• Fits OEM crank bolt pattern and dimensions for easy installation on compatible engines
• Simple hand tools typically required; torque wrench recommended for crank bolt
• Carb jet adjustments and valve checks recommended after swap for optimal performance
• Do not attempt installation on non-Hemi Predator or incompatible engines

Who is this for: Enthusiasts and mechanics upgrading small displacement Hemi-style engines—mini bike and go-kart racers, DIY tuners, and anyone needing a robust flywheel assembly with basic tuning parts included. If you own a Predator 212 Hemi (60363), a GX160/GX200 clone, or a vehicle listed in the compatibility notes, this EOPOAYI kit supplies a ready-to-install, performance-minded replacement. Confirm your engine model before purchase to ensure proper compatibility.
