K3 EVO is a pre-grinding engine. After opening the package, you only need to spend about 2-4 barrels of oil (250-500c.c) in the tank of the car, and then use 30-80% of the throttle to run the 2-4 barrels of oil (tank of the car) slowly and at full speed. This process can be completed in the yard. After running 2-4 barrels of oil (tank of the car), the engine can go on the stage to race. It's fast.

The new K3 EVO engine has made the following changes:

1. The carburetor with ceramic coating and three oil needles is designed to be more precise and easy to adjust. The atomization efficiency is improved in order to provide more torque. The balanced crankshaft of the dynamic balancing crankshaft also produces a more stable engine with stable and predictable low center of gravity.

2. The K3 EVO cylinder is designed with aluminium alloy piston, brass cylinder and high strength connecting rod. The scavenging cylinder liner has linear power sense and low fuel consumption. The grinding cylinder can improve power quality.

3. Piston connecting rod is made of high-quality aluminium alloy material. After our engineer's selection, it has more durability, while maintaining the lightweight performance of K 3, almost double the endurance, plus the reliability of the engine.

4. The new high-precision ceramic peeling reduces the resistance of rotation, increases engine speed and reduces fuel consumption, and ensures the stability of idle speed and low friction at high temperature and high speed.

5. Hollow piston tip is used to reduce weight. High specification material can also make piston tip lighter. Light piston tip can make our engine run faster.

6. The engine body is manually selected, and one is within the tolerance of the ideal range. The appearance of the cloth radiator and the black coated engine body make the cooling performance more excellent. It is made by special hardening treatment and close pin processing.

7. The crankshaft is made of dynamic balanced crankshaft counterweight and selected high-quality steel. The efficiency of the mixture entering the crankshaft is improved by expanding the intake port. The crankshaft uses a special shape to increase the stability in the crankshaft box.
