What oil does a Harley 750 use?

Harley 750 uses AMSOIL 20W-50 oil. Introduction to engine oil: Engine oil is the lubricant used by the engine, composed of base oil and additives. The density of engine oil is approximately 0.91×10 cubic meters per kilogram to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. Introduction to base oil: Base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil, imparting certain new properties, making them an important part of lubricating oil.

Can Headlight Cracks Be Repaired?

Headlight cracks are difficult to repair. Specific reasons: If the headlight housing develops cracks, it is very challenging to repair them. Even if the cracks are sealed, there will be a noticeable glue mark on the surface, which will inevitably affect the headlight's illumination performance and may even pose safety hazards. Therefore, when the headlight housing is cracked, it is advisable to promptly visit a repair shop or 4S store for a replacement. Handling methods: You can seek out a nearby repair shop with relevant experience to polish the surface of the headlight housing. If polishing is not feasible, to reduce vehicle maintenance costs, you may opt not to replace the entire headlight assembly. Instead, you can visit a specialized auto beauty repair shop that modifies headlights to replace the headlight cover, which is far less expensive than replacing the entire headlight assembly.

What does 85w90 mean for transmission oil?

Transmission gear oil 85w90 is a viscosity grade designation. The 'W' in the viscosity grade designation of gear oil stands for winter-type gear oil. The number before the 'W' indicates the low-temperature viscosity, where a smaller number means lower viscosity, better fluidity, and stronger low-temperature performance. The number after the 'W' indicates the high-temperature viscosity, where a larger number means higher high-temperature viscosity and the ability to withstand higher temperatures. The types of transmission oil are as follows: Transmission oil is generally divided into three types: manual transmission oil, automatic transmission oil, and continuously variable transmission oil. Manual transmission oil is commonly known as gear oil. Automatic transmission oil is commonly known as gearshift oil (ATF). Continuously variable transmission oil is commonly known as traction oil (CVTF). The functions of transmission oil are as follows: Reduce friction, minimize wear, and control the friction of the clutch and the performance of the synchronizer. Load-bearing (low-speed high torque, vibration load), heat dissipation, vibration and noise reduction, and removal of contaminants at gear meshing points (cleaning function). Prevent corrosion, pitting, and surface metal tearing, isolate metal surfaces, and prevent direct contact between metal bodies.

Should Turning Vehicles Yield to Straight-Going Vehicles When Driving?

When driving, turning vehicles should yield to straight-going vehicles, but not all the time. Vehicles going straight on the auxiliary road must yield to vehicles turning into the main road: Roads are divided into main roads and auxiliary roads. No matter the direction, as long as you are driving on the auxiliary road, you must yield to vehicles on the main road. Some intersections may also have yield signs, so be sure to slow down and not force your way through. When encountering an inverted triangle yield sign on the road: When driving past such signs, you must slow down and yield, waiting for other vehicles to pass before proceeding. If you force your way through and an accident occurs, you will bear full responsibility. Even if you are going straight, you must yield to turning vehicles.

Why can motorcycles only be started in neutral gear?

Motorcycles can only be started in neutral gear, possibly due to considerations of load and safety. Load issue: If started with the wheels engaged, the resistance increases, which can cause damage to the starter motor and starter gears. Safety: If the engine and wheels are connected during startup, the engine will directly drive the wheels to rotate, causing the entire vehicle to lurch forward. Internal combustion engines operate explosively during startup, which would naturally cause the vehicle to surge forward abruptly. Therefore, motorcycles are designed to only allow starting in neutral gear or with the clutch engaged, as a safety consideration.

Do I Need to Change the Rims When Replacing Regular Tires with Run-Flat Tires?

Replacing regular tires with run-flat tires does not require changing the rims. Theoretically, for current vehicle models, as long as the specifications match, they can generally be replaced directly. Precautions: Since run-flat tires have certain impacts on the car's suspension, shock absorption, chassis, and other aspects, models originally equipped with run-flat tires have undergone certain debugging and matching, so the impact will be reduced. However, for regular models, caution is necessary. It is recommended to go to a professional tire shop for replacement, which will also be more reliable. Lower Comfort of Run-Flat Tires: Due to the need to continue driving when the tire is flat and differences in internal structure, run-flat tires are harder than regular tires, with poorer shock absorption and noise reduction performance. Reducing unsprung weight, run-flat tires are heavier than regular tires.
