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).

What Are the Symptoms of Spark Plug Failure?

Spark plug failure manifests in the following symptoms: Difficulty in starting the car, both during cold starts and hot starts, often requiring multiple attempts. Engine shaking, noticeable vibrations while driving. Reduced power, a significant decrease in performance compared to normal conditions. Increased fuel consumption. Engine stalling. Failed emissions tests. Common causes and diagnostics of spark plug failure: Several conditions can lead to spark plug malfunction: Incorrect spark plug gap adjustment. A gap that is too small limits the contact area between the spark and the air-fuel mixture, while also suppressing flame kernel growth due to the quenching effect of the electrodes. This results in weak sparks and difficulty igniting the mixture. Conversely, a gap that is too large may exceed the ignition system's voltage capacity, preventing sparking. Cracked spark plug insulator. High-voltage current leaks through the crack, preventing sparking at the electrodes. Electrode carbon buildup, causing current leakage from the center electrode to the surroundings instead of jumping to the side electrode. Excessive carbon deposits can short-circuit the spark plug, preventing sparking and damaging the insulator. Damaged electrodes. Prolonged electrical erosion from sparks or chemical corrosion from combustion gases can cause electrodes to break or detach, rendering the spark plug ineffective. Low insulation resistance in the spark plug. This reduces the ignition voltage across the spark gap, weakening or completely eliminating the spark. Short circuit in high-voltage wires. Leakage in the wire from the ignition coil to the distributor prevents the entire engine from starting, while leakage in the wire from the distributor to a spark plug affects only that cylinder. Eroded contact points in the distributor. This can prevent all spark plugs from firing, making the engine unable to start or run properly. Spark plug failure requires timely replacement. The replacement steps are as follows: Open the hood and remove the engine's plastic cover. Disconnect the high-voltage wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove each spark plug, ensuring the area is free of debris like leaves or dust before proceeding. Insert the new spark plug into the hole, hand-tightening it before using the socket for final tightening. Reattach the high-voltage wires in the correct firing order and replace the cover. Replacement interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so consult the owner's manual for specific recommendations.

How to Eliminate the Illuminated Engine Fault Light?

If the engine fault light is illuminated, you can follow these steps to address the issue: First, check whether the engine is running normally. Look for issues such as shaking, black smoke emission, or difficulty starting. If any of these problems are present, avoid restarting the engine. Particularly, if the light is red, do not attempt to start the engine again. If the engine is running normally and the vehicle can be driven, proceed to a service station as soon as possible to diagnose the issue. The service station can easily read the fault codes using a portable diagnostic tool, obtaining specific fault information for targeted repairs. If the engine is running normally, the owner can also try gently reconnecting various wiring harness connectors, as a loose connection might be the cause. Alternatively, repeatedly turning the key to the ON position may help eliminate the light. Generally, the illumination of the engine fault light can be attributed to the following seven main causes: Sensor Malfunction: This includes sensors such as the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake temperature sensor, and oxygen sensor. When these sensors are damaged, have poor connections, or their signals are interrupted, the vehicle's ECU cannot accurately obtain engine data, triggering the engine fault light. Fuel or Oil Quality Issues: Failure to use the fuel or oil specified by the manufacturer may cause engine wear, leading to the illumination of the fault light. Poor Combustion of Air-Fuel Mixture: Poor combustion can result in engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the fault light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion of the air-fuel mixture. Turbocharger Problems: Issues with the intake boost piping or turbocharger can also trigger the engine fault light. The most common problem is a damaged turbocharger, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Problems: If the vehicle's intake system is compromised, it may lead to blocked engine pipes, which can, in severe cases, cause the engine fault light to illuminate. A dirty air filter that hasn't been cleaned regularly can also lead to intake issues. Exhaust Problems: Exhaust system faults can also trigger the engine fault light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is the most frequent culprit. Using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily lead to catalytic converter failure. Anti-Theft System Malfunction: If the vehicle's electronic anti-theft system fails or if there is a mismatch between the anti-theft controller and the engine electronic controller, the anti-theft system can prevent the engine from operating normally, accompanied by the illumination of the engine fault light.

How to Repair a Broken Belt?

For small and shallow cracks or scratches on leather, you can apply a small amount of cream or shoe polish to the worn area. For larger and deeper cracks, or even if the belt is broken, it is best to take it to a professional leather repair shop. For regular maintenance of high-end leather products like genuine leather belts, you can apply a small amount of petroleum jelly to the edges or areas prone to wear.
