The optimum profile that maximizes the performance of the normal cylinder head improves output performance.
By attaching it to a normal engine, the output in the high rotation range is improved.
When the decompression part is removed from the normal camshaft and attached to the sports camshaft, it becomes an auto decompression mechanism.
When only the camshaft is installed in the normal piston and normal muffler state, the injection controller is not required.
When a sports camshaft and our muffler are installed at the same time, an injection controller suitable for each vehicle is required.
