Must Straight Driving Be in the Middle of the Road?

Straight driving is easier to pass when staying in the middle. During straight driving, the driver can align with the central arrow, at which point the vehicle is slightly to the right of the road center. Since it is a straight driving section, alignment is sufficient for straight driving. Below is extended information about straight driving: Straight Driving: Straight driving refers to novice drivers starting the vehicle, gradually accelerating to shift from the lowest gear to the highest gear, achieving high speed. Assessment Requirements: Smooth start, basically orderly driving operations; ability to correctly handle the steering wheel (primarily operated with the left hand) and use the steering wheel's free play to adjust driving direction; mastering the timing and methods of gear shifting, adept at switching between high and low gears at various speeds (sequential upshifting, sequential downshifting, or skip downshifting); timely and effective use of the brake (predictive braking deceleration); basic proficiency in fixed-point stopping and intersection U-turns.

At what mileage should the second maintenance for a motorcycle be performed?

Motorcycles have a break-in period of 1,500 kilometers. During this period, engine oil should be changed at 300 kilometers, 600 kilometers, 1,000 kilometers, and 1,500 kilometers. Therefore, the second oil change should occur when the vehicle has traveled approximately 600 kilometers. Below are more related details: Precautions for changing engine oil: It is not recommended to use fully synthetic oil during the break-in period because fully synthetic oil has superior anti-wear properties. The break-in period is designed to properly wear in various components, so there may be cases where the break-in mileage is reached but the engine is not yet properly worn in. Multi-cylinder, large-displacement motorcycles should not use automotive engine oil, even fully synthetic oil. This is because the vast majority of cross-type motorcycles use wet multi-plate clutches, where the clutch plates are immersed in the engine oil. Motorcycle-specific oil contains additives to prevent clutch plate slippage, which automotive engine oil lacks.

What Causes the Squeaking Noise When the Front Motorcycle Suspension Compresses?

Here are the reasons for the squeaking noise when the front motorcycle suspension compresses: Check the shock absorber: Perform a visual inspection of the suspension shock absorber, which is non-disassemblable and considered a one-time-use component. If the shock absorber appears bent, severely dented, or punctured during inspection, it should be replaced. Performance check: Conduct a performance check by pressing down on the vehicle with your hands and then quickly releasing. If the vehicle bounces more than twice, it indicates poor shock absorber performance, and the shock absorber should be replaced. Check for oil deficiency: Inspect whether the shock absorber lacks oil. An on-vehicle inspection can also be performed: Look for signs of oil leakage. After running the vehicle, perform a touch inspection. After operating for a while, stop the vehicle and quickly touch the shock absorber cylinder with your hand. If the cylinder feels hot to the touch, it indicates the shock absorber is functioning normally.

What do F and E mean on a motorcycle?

Motorcycle E stands for "Empty," indicating the fuel tank is empty, while F stands for "Full," meaning the fuel tank is full. Below is an introduction to motorcycle fuel gauge knowledge: Meaning of the scale: The E and F on the right gauge of a motorcycle represent the fuel level in the tank, with the middle scale indicating the remaining amount of fuel; when the fuel gauge pointer reaches the red zone in the E direction, there is approximately one-third to one-quarter of the total fuel tank capacity left, and it is time to refuel promptly. Fuel gauge maintenance: Like other gauges, it is designed and manufactured with a series of measures to prevent vibration, water, and dust. Since motorcycles operate on roads with varying environmental conditions, the working conditions of the motorcycle fuel gauge are relatively harsh. Therefore, preventing vibration, water, and dust is key to fuel gauge maintenance. During normal riding, try to minimize motorcycle vibration, such as ensuring the tire pressure is inflated according to regulations and not overinflated. The amount of shock absorber oil in the front suspension must be filled according to the specified quantity, neither overfilled nor underfilled, to reduce motorcycle vibration to the minimum extent.

Does a motorcycle need to undergo an on-site inspection in its sixth year?

6-year exemption from inspection still requires an on-site inspection in the sixth year. For example, if a vehicle meets the exemption conditions and the exemption period starts from 2014, it means that during the six years from 2014 to 2019, you can enjoy two opportunities to skip the on-site inspection, only needing to apply for the annual inspection sticker every two years. However, in the sixth year (i.e., 2019), an on-site inspection is required, and you must also apply for the annual inspection sticker at the same time. In other words, the six-year exemption does not include the sixth year. Here is more related information: 6-year exemption from annual inspection does not mean 6-year exemption from annual review: Vehicles that meet the 6-year exemption conditions are only exempt from the on-site inspection (i.e., vehicle inspection) process, but they still need to apply for the annual inspection sticker every two years. This means the exemption only saves the vehicle owner the trouble of the vehicle inspection process, while the annual inspection sticker must still be applied for every two years.
