HIAORS Aluminum Flywheel 10krpm for Predator/GX160 GX200 Minibike — Lightweight 8° Advance, Includes Tuning Kit

This billet-style flywheel swaps into a range of 6.5–224cc clone and OEM small engines (Predator non‑hemi, GX160/GX200 clones, Tillotson 212cc, Coleman CT200U series and similar) to free up horsepower by cutting rotational air resistance while preserving adequate cooling. It arrives as a kit with valve springs, a main jet set and a crankshaft key so you can tune ignition and fueling after installation. Built from cast aluminum with reinforced hub threads and an 8° built‑in timing advance, it’s designed to be lighter than stock iron/plastic flywheels and more durable under repeated use.

How does this flywheel improve acceleration and top‑end performance?

Reducing the rotating air drag around the crankshaft lets more of the engine’s output reach the drivetrain, which typically yields sharper throttle response and higher rev potential. The lighter mass also reduces rotational inertia, so the engine can spool up quicker and sustain higher rpm under load.

• Ultra‑low drag aluminum profile lowers airflow resistance around the crank.
• Reduced rotational mass improves throttle response and acceleration.
• 8° built‑in timing advance optimizes ignition for higher rpm ranges.
• Includes tuning parts (valve springs and main jets) to match performance goals.

Will this fit my Predator 212, Tillotson 212, GX160/GX200 or Coleman CT200U engine?

The flywheel is made to fit many 196–224cc non‑hemi Predator-style and several clone engines, plus GX160/GX200 6.5hp style clones and Coleman CT200U series minibike engines. It is not compatible with Predator 212 Hemi heads; confirm crank and keyway compatibility before ordering.

• Compatible: Predator non‑hemi 196/212/224cc, Tillotson 212, GX160/GX200 clones, CT200U/CT200U‑EX, BT200X and many go‑karts.
• Not compatible: Predator 212 Hemi models and engines with differing crank taper/keyway specs.
• Check physical crank diameter, keyway size and bolt pattern to be certain of fit.
• Includes metal crankshaft key for installation where applicable.

What materials and design features ensure durability and cooling?

Constructed from cast aluminum, the HIAORS flywheel is both lighter and more heat‑resistant than typical iron or plastic stock units. The central hub has reinforced threaded holes to protect the taper and keyway area during installation and repeated use.

• Cast aluminum body for weight savings and corrosion resistance.
• Durable hub threads to prevent taper damage and maintain secure mounting.
• Designed to maintain sufficient airflow for cylinder cooling despite lower drag.
• Includes balancing notes — minor casting marks don’t affect normal operation.

What’s included and what tuning options are provided?

The package gives you the main hardware to replace the flywheel and basic parts to fine‑tune performance. Valve springs and a main jet kit allow adjustments to fuel delivery and valve control for higher rpm use.

• 1 × aluminum flywheel with 8° built‑in timing advance.
• 2 × 26 lb valve springs to support higher lift/speed operation.
• Main jet kit: emulsion tube plus .036, .037 and .038 main jets for richer/leaner trials.
• 1 × metal flywheel crankshaft key included for secure installation.

Who is this for? This HIAORS flywheel kit is aimed at hobbyists, minibike and go‑kart builders, weekend racers and small‑engine tuners who want a reliable, lightweight upgrade to extract more usable power and revs from compatible 196–224cc clone and OEM engines. It’s suited to mechanically competent users who can verify fitment, perform flywheel installation, and carry out basic carburetor and ignition adjustments. Avoid use on engines listed as incompatible, and balance the assembly if precise high‑rpm operation is required.
