Motorcycle Engine:
The cylinder body is level, so that the cylinder can avoid obstacles on the front wheels of the motorcycle and obtain good air-cooled heat dissipation performance. Two symmetrical exhaust pipes are one of the hallmarks of a horizontally opposed engine. The advantage of this model lies in its ingenious structural design, and every component restores the mechanical principle. An all-metal engine model that can be started and operated
Sophisticated Manufacturing:
We use precision casting for the entire engine, and each part is carefully crafted. The contour of the cylinder and the casting process of other parts are very round, which became the most significant feature of motorcycles in that era. You will feel the unique charm brought by the mechanical operation of the engine.
Steps to start the engine:
(1) Check the engine wiring from the wooden base, connect the fuel tank oil pipe, and install 3 AA batteries (4.5V);
(2) Fill the fuel tank with 95# gasoline. The flywheel rotates clockwise multiple times on the right side of the engine (the surface of the power switch), its function can make the mixed fuel completely enter the cylinder and ensure that there is no air in the fuel pipe;
(3) Turn on the power switch, and then quickly turn the flywheel clockwise to stop the engine Start the engine on the right side (surface of the power switch)
(1) If the ignition device is normal and the cylinder compression is normal, and the machine cannot start normally, it is likely to need to adjust the carburetor oil needle;
(2) After tightening the main oil needle on the carburetor, loosen 1 /4 turns and start the flywheel to make the mixing ratio of gasoline and air reach the normal working mixing ratio;
(3) When the machine stops running, turn off the power switch
