WH Camshaft Assembly

🏍️ Camshaft · Performance Upgrade · High Torque Cam · 4-Stroke Tuning Part

For 125cc-150cc 4-Stroke Scooters · Improves Torque & Acceleration · 34 Teeth

📋 Product Overview

This is the WH Camshaft Assembly — one of the most cost-effective ways to achieve real performance tuning. Through close collaboration with various 4-stroke scooter manufacturers, we have successfully increased engine performance and running smoothness. This product delivers noticeable performance gains without compromising everyday drivability, maintaining smooth operation and excellent durability.

As the heart of the engine's valve train, the camshaft controls the timing and lift of the intake and exhaust valves. This camshaft features an optimized profile that provides higher torque output without sacrificing daily usability, resulting in better acceleration. It can be used with original (restricted) engines and fits all 125cc-150cc cylinder kits. Installation is easier and quicker than replacing the complete cylinder, making it an ideal entry-level performance upgrade.

✨ Core Functions: Optimize valve timing · Increase torque output · Improve acceleration · Maintain everyday drivability · Easy and quick installation

⚡ Performance Benefits

📈 Higher Torque

Optimized cam profile increases valve lift and duration, delivering significantly improved mid-range torque output.

🚀 Better Acceleration

Higher torque translates directly into stronger acceleration, making starts and overtaking more responsive.

🔧 Easy Installation

No need to replace the entire cylinder — simply swap the camshaft for noticeable performance gains with less work.

🛡️ Daily Usability

Optimized design maintains idle stability, fuel economy, and durability for everyday riding.

💡 Why Upgrade the Camshaft? The camshaft is the key component that determines engine "breathing" efficiency. By optimizing valve timing and lift, more air enters the cylinder for better combustion, delivering significant performance gains without major engine modifications. This is one of the most cost-effective power upgrades for 4-stroke scooters.

🔧 Compatibility

This camshaft assembly is compatible with the following vehicles and engines:

Engine Type: 4-stroke scooter engines (GY6, 153QMI, 152QMI, etc.)
Displacement Range: 125cc - 150cc
Compatible Cylinders: All 125cc-150cc cylinder kits (both OEM and aftermarket)
Compatibility: Works with original (restricted) engines as well as performance cylinder kits

📌 Compatibility Note: This camshaft features 34 teeth and fits most 125cc-150cc 4-stroke scooter engines. Before installation, verify that your original camshaft has the same tooth count.

⚙️ Importance of the Camshaft

🔄 Controls Valve Timing

Precisely controls when intake and exhaust valves open and close, determining the engine's "breathing" rhythm.

📏 Determines Valve Lift

The height of the cam lobe determines how far the valves open, directly affecting airflow and combustion efficiency.

💪 Affects Power Output

Camshaft design directly determines the engine's torque characteristics and power curve.

🌿 Impacts Fuel Economy

Optimized valve timing improves combustion efficiency, leading to better fuel economy.

✨ Product Features

Optimized Cam Profile: Precision-designed and tested to deliver power gains while maintaining smooth operation.
High-Precision Machining: Manufactured with precision machining processes to ensure accurate cam lobe profiles and surface finish, reducing friction loss.
High-Quality Material: Made from high-strength alloy cast iron or steel, heat-treated for durability and wear resistance.
34-Tooth Design: Standard tooth count compatible with most 125cc-150cc 4-stroke scooter engines.
Direct Replacement: Drop-in installation with no modifications required for noticeable performance improvement.
Excellent Value: Compared to replacing the entire cylinder, camshaft upgrade offers lower cost, significant results, and easier installation.

🔧 Installation Guide

1. Ensure the engine is cool and disconnect the negative battery terminal before starting.
2. Remove the valve cover, timing chain or belt, and note the timing mark positions.
3. When installing the new camshaft, align the timing marks precisely to ensure correct valve timing.
4. It is recommended to replace the camshaft oil seal at the same time to prevent oil leaks.
5. When reinstalling the timing chain, ensure the tensioner is functioning properly and chain tension is correct.
6. After installation, manually rotate the crankshaft several times to confirm there is no interference or binding.
7. Start the engine and check for stable idle and unusual noises; re-adjust valve clearance if necessary.
