Piston Adopting micro-arc oxidation treatment to its head for heat insulation, it can

prolong piston using life and effectively improve the problem or whining.(CG175/

CG200).

Use the lightweight piston to reduce the weight of the piston, This new piston

can reduce the inertia force during the operation of a crank unbalance, improve

engine vibration.(CG250).

Clutch Adopting 6 spring and 6 column & BM103 firction plates to make clutch

connection more even and wearable for much longer using life.(CG175).

Using six springs six columns, BM103 friction plate, making clutch more stable

and wearable, A substantial increase in life.(CG200/CG250).

Push rod Using alloyed push rod to effectively reduce noise.(CG175/CG200).

Using integrated putter, improved the reliability of the engine.(CG250).

Crankshaft assy Using KU fine needle to improve engine reliability.(CG175).

Use the KU needle and increase the crankshaft bearings to stronger the

bearing capacity, improve engine reliabilitu. Assemble the crankshaft and the

housing under the hot pressure to reduce the noise of the engine.(CG200).

Use the KU needle and increase the crankshaft bearings to stronger the

bearing capacity, improve engine reliability. Assemble the crankshaft and the

housing under the hot pressure to reduce the noise of the engine.(CG250).

Cylinder Adopting the technology of plateau cross hatch, make it easier to form oil film,

it can improve lubrication of cylinder and piston and its rings,and make it more

reliable.(CG125/CG200/CG250).

Crankcase Special designed box maze can improve balance for the exhaust gas, prevent

the oul injection form the exhaust pipe, reduce the oil consumption.(CG250).
