Where is the Yamaha oil drain port located?
1 Answers
Yamaha motorcycles have two oil drain ports. The one at the bottom left side of the engine is usually more convenient for routine oil changes. There is a larger plug at the bottom right side of the engine, which houses the oil filter screen. During regular maintenance, this can be removed to inspect and clean the oil filter screen. Generally, as long as qualified oil is replaced periodically, the screen won't get clogged, so frequent removal for cleaning isn't necessary. Below is some related information about the Yamaha NMAX155: 1. Power: This model is equipped with a single-cylinder water-cooled SOHC 4-valve engine, delivering a maximum power of 11.3 kW (at 8000 rpm) and a maximum torque of 13.7 N·m (at 6500 rpm). It reduces friction and power loss, improves combustion efficiency, and enhances cooling performance, resulting in stronger acceleration, higher top speed, and effectively lower fuel consumption. 2. Frame structure: The NMAX155 features a lightweight steel tube frame with a low-beam design, making low-speed handling easier while providing sufficient rigidity at high speeds. The suspension system consists of a 100mm travel telescopic front fork and a standard twin-tube rear shock absorber (the overseas high-end version comes with a twin-tube shock absorber with a gas reservoir).
