Yamaha FZ16 150 Original Camshaft Decompression Cam

The decompression cam facilitates the engine starting process. Its main function is to temporarily reduce the compression pressure in the cylinder during starting. This is achieved by opening an exhaust or intake valve in the cylinder at the right time, which relieves the crankshaft's resistance to rotation. To ensure your motorcycle's decompression cam lasts a long time and works well, you must take care of it. This means changing the oil with a good one and not forcing it when starting the engine. It's also important to prevent it from getting too hot and to drive gently to avoid stressing the engine. The decompression cam transforms starting into a smooth and hassle-free process.
