What is the reason for a motorcycle revving but not moving?

The reason for a motorcycle revving but not moving is: the carburetor is too dirty and needs cleaning, check the air filter, and then check the gasoline, as there may be water in the gasoline. A motorcycle consists of an engine, transmission system, running system, braking system, and electrical instrumentation equipment. The transmission system of a motorcycle is composed of primary reduction, clutch, gearbox, and secondary reduction. The solutions for a motorcycle that is difficult to start are: 1. Check the carburetor, fuel mixture ratio, oil level, and choke; 2. Check if the valve clearance is too small or if there is air leakage; 3. Check if the high-voltage spark for ignition is strong; 4. Open the choke to force start.

Where is the OBD interface of the Ouliv?

The OBD interface of the Ouliv is located below the left side of the steering wheel. OBD refers to the On-Board Diagnostics system in the vehicle, and the interface below the left side of the steering wheel serves as the bridge connecting the computer to the vehicle's diagnostic system. Through this interface, using professional diagnostic tools and specific procedures, fault codes can be read from the PCM. Based on the fault codes, maintenance personnel can quickly and accurately determine the nature and location of the fault for timely repairs. The main function of the On-Board Diagnostics system is to monitor the operating conditions of the engine, as well as the status of vehicle exhaust emissions. As long as the engine is running, the vehicle will produce exhaust. Once the On-Board Diagnostics system detects a situation that may lead to excessive emissions, it will immediately issue an alarm to alert the driver. The body dimensions of the Ouliv are 3995mm in length, 1735mm in width, and 1710mm in height, with a wheelbase of 2505mm.

Is it normal to have oil inside the exhaust valve?

It is abnormal to have oil inside the exhaust valve, which may be caused by aging of the crankcase ventilation valve or faults in the piston, cylinder liner, piston pin, and piston rings, resulting in loss of their original sealing effect and leading to oil spraying. The reasons for oil in the exhaust pipe may include severe wear between the valve stem and valve guide, creating excessive clearance and causing oil to leak downward. The exhaust valve, also known as the oil separator or pressure control valve, is installed between the compressor outlet and the condenser inlet. Through separation, it improves the heat transfer effect in the condenser and evaporator. The working principle of the exhaust valve: High-pressure gas (gaseous working medium and lubricating oil) from the compressor enters the exhaust valve and then the guide vanes of the exhaust valve, flowing in a spiral pattern along the vanes. By centrifugal force and gravity, the lubricating oil is separated from the working medium gas and flows down along the inner wall of the cylinder. The working medium gas is led out of the exhaust valve through a multi-hole baffle via the central pipe. The separated lubricating oil accumulates in the lower part of the oil separator and can be periodically discharged or automatically returned to the compressor's crankcase using a float valve.

Does a small chip on the wheel hub require replacement?

If a small chip on the wheel hub can be repaired, replacement is not necessary. The wheel hub is the rotating part of the tire's inner rim connected to the wheel core via spokes, which is the metal component supporting the tire, also known as the rim, steel wheel, or wheel disc. Types include painted wheel hubs and chrome-plated wheel hubs. Maintenance methods for wheel hubs are: 1. Avoid using cold water for cleaning when the wheel hub is at a high temperature; 2. In humid environments, clean the wheel hub frequently to prevent salt corrosion on the aluminum surface. The functions of the car wheel hub are: 1. To serve as the mounting point for the axle, supporting the tire and cushioning external impacts; 2. To ensure contact between the tire and the road surface, maintaining the vehicle's driving performance.

At how many kilometers is a motorcycle scrapped?

Motorcycles are scrapped at 100,000 kilometers. A motorcycle is a two or three-wheeled vehicle driven by a gasoline engine and steered by handlebars to control the front wheel. They are lightweight, flexible, fast, and widely used for patrols, passenger and cargo transportation, and also serve as sports equipment. Broadly speaking, motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes. The method to start a motorcycle is: 1. Use the main stand to support the bike on flat ground; 2. Stand in the direction the kickstarter is pressed—if the kickstarter is pressed forward, face forward and step on it to start; 3. If the kickstarter is pressed backward, face backward and step on it to start.
