The heat generated by long-term vehicle driving and continuous engine operation can quickly and evenly spread, preventing problems such as local heat accumulation in the cylinder head, high temperature overheating, thermal decay and lagging. At the same time, the material has oil resistance and high temperature oxidation resistance, which can resist oil corrosion and high temperature exhaust oxidation loss. The inner wall of the cylinder body is not easily corroded, the airway is clogged with carbon, and the material is aging and brittle.

1.3 Complete set of high-end core accessories, wear-resistant and low failure rate

The internal components adopt standard matching components, and the product is equipped with thickened precision intake and exhaust valves, which have undergone hardening and strengthening treatment. The overall hardness is high, and long-term high-frequency opening and closing work is not easy to wear, deform, or close tightly, ensuring the accuracy of the valve distribution structure; The combination of high toughness inner and outer double springs has long-lasting elasticity, and long-term high-speed operation is not prone to elastic attenuation, maintaining valve opening and closing timing and sealing. High and low temperature resistant valve oil seal, stable and long-lasting sealing effect, not easy to age, harden, crack and leak.

2. Heat resistant manufacturing process, long-term stable operation

2.1 Thickened heat dissipation fins for fast heat dissipation and high temperature attenuation prevention

Haomai 150 GY6 150 Complete Cylinder Head 157QMJ Engine Parts Adopting thickened and widened heat dissipation fins to create a shape, effectively expanding the air circulation and heat dissipation efficiency. In response to the long-term high load operation of GY6 engine, the heat dissipation fins can quickly and evenly remove the core high temperature generated by engine operation, avoiding heat accumulation and retention inside the cylinder block. Effectively eliminating common problems such as high temperature overheating, thermal power decline, continuous high temperature cylinder burning, and idle high temperature abnormal noise, ensuring that the engine operates continuously at a constant temperature for a long time, completely solving the shortcomings of ordinary cylinder heads that are not resistant to high temperatures and prone to failures in summer, and greatly improving the stability of the entire machine under high temperature conditions.

2.2 CNC precision grinding sealing process to eliminate hidden dangers of oil and gas leakage

The core sealing contact surface of the cylinder head is processed by CNC precision grinding, and the flatness is manually calibrated twice. The end face of the cylinder body is flat and uniform, without burrs or concave and convex defects. It has a high degree of adhesion with the cylinder gasket, uniform force distribution, no edge warping, and no pressure deviation. Eliminate cylinder head leakage, gas leakage, insufficient pressure and other faults that occur during engine operation, maintain stable cylinder pressure inside the engine, and ensure sufficient power output.

2.3 CNC precision grinding sealing process to eliminate hidden dangers of oil and gas leakage

Before leaving the factory, the finished products undergo a complete set of quality inspection processes, including high-pressure pressure testing, whole machine air tightness and sealing testing, high and low temperature cold and hot cycle aging testing, dynamic operation noise verification, and gas distribution accuracy calibration. These processes eliminate defective products, substandard products, and products with low accuracy, greatly reducing the frequency and maintenance costs of vehicle maintenance in the later stage.

3. Full compatibility of multiple vehicle models

3.1 Non destructive and easy installation

Haomai 150 GY6 150 Complete Cylinder Head 157QMJ Engine Parts installation hole positions, airway structures, and pipeline interfaces are all 1:1 replicated from the original factory standards. Support non-destructive direct installation replacement, simplify installation process, save maintenance time, adapt to store quick replacement and personal self installation, easy to install and complete in one go.

3.2 Wide compatibility with multiple vehicle models

The product is compatible with the Haomai 150 series of old scooters, as well as mainstream domestic GY6 125/150cc four stroke pedal motorcycles such as Guangyang and Haojue. It can also be perfectly compatible with ATV beach bikes, off-road go karts, small commuting power equipment, etc. equipped with the same GY6 engine. Suitable for a wide range of people and commercial scenarios, catering to various needs such as personal maintenance and replacement, store stocking, and cross-border bulk supply.

Analysis of common problems in motorcycle cylinder heads and determination of replacement needs

1. Engine overheating and severe power degradation due to high temperature

The heat dissipation ability of ordinary cylinder heads is weak, and long-term use is prone to heat accumulation and deformation. During long-distance driving, problems such as high water temperature, engine overheating, weak power, and weak acceleration may occur. The main reasons are insufficient heat dissipation, deformation of the cylinder head plane leading to insufficient cylinder pressure, and decreased combustion efficiency. Replacing this thickened heat dissipation and anti deformation upgraded cylinder head can stabilize engine power output.

2. Cylinder head oil leakage, air leakage, idle shaking, and increased fuel consumption

Old cylinder heads are subject to high temperatures and vibrations for a long time, causing deformation of the end face and aging and failure of the oil seal, leading to problems such as cylinder head air leakage, oil seepage, and gas leakage, resulting in vehicle shaking and increased fuel consumption. Simply replacing gaskets and oil seals can only provide temporary relief. Replacing the cylinder head assembly of this model can solve the problem of sealing failure from the root.

3. Abnormal valve noise, difficulty in cold starting, and high operating noise

The wear of the original cylinder head valve and the fatigue decline of the spring can cause problems like abnormal valve noise, difficulty in cold starting, idle noise, and acceleration lag. Long term use can sharpen engine wear, leading to major malfunctions such as valve jacking and cylinder pulling. This cylinder head is equipped with new valves and high strength springs, with nifty valve distribution and tight closure, making the engine run smoother and quieter.

4. Abnormal exhaust gas, severe carbon deposition, and unstable working conditions

Blockage and sealing damage of the cylinder head airway can bring unbalanced

intake and exhaust, inadequate fuel combustion, abnormal exhaust discharge, noticeable carbon buildup, astable engine operating conditions, and quicken internal parts wear and tear. Replacing the original factory standard cylinder head can recover normal intake and exhaust efficiency, optimize fuel combustion, and cut down carbon buildup.
