Can Motorcycles with Modified Projector Headlights Pass the Annual Inspection?

Motorcycles with modified projector headlights can pass the annual inspection. As long as the brightness of the headlights meets the requirements, modifying the projector itself is not illegal. The motorcycle inspection line mainly checks the effectiveness of all lights and braking performance. The annual vehicle inspection is primarily based on the National Standard of the People's Republic of China GB7258-2012 "Safety Technical Specifications for Motor Vehicle Operation". Exterior Inspection: The exterior inspection mainly checks whether the vehicle's appearance is damaged, whether it matches the original vehicle's appearance, and whether there are obvious modifications. For many young motorcycle riders today, there are numerous modifications to vehicle components. For example, many motorcycle enthusiasts like to modify the exhaust system or install crash bars. Some regions allow these modifications to pass, while others do not and require the vehicle to be restored to its original condition. Therefore, riders should refer to the strictness of motorcycle annual inspections in their local area. Emissions Testing: Emissions testing is a mandatory item for all motor vehicles. Before the test, the staff will verify whether the motorcycle's serial number matches the one on the vehicle registration certificate and briefly inspect the overall appearance of the vehicle. Then, the emissions test begins. Generally, motorcycles have a very high pass rate for emissions tests, unless the vehicle is in poor condition due to long-term neglect.

Can I Buy Tires That Have Been in Stock for 3 Years?

Tires that have been in stock for three years cannot be used because the service life of tires is generally around 2-3 years or 60,000-100,000 kilometers. Tires are consumables for a car, just like brake pads, engine oil, and oil filters, and they will wear out with increased mileage, eventually needing replacement. When replacing new tires, many people not only pay attention to performance factors such as grip, drainage, comfort, wear resistance, and noise but also consider the price, which plays a decisive role. Pay Attention to the Tire Date: The production date of the tire is also marked on the sidewall. First, look for the letters "DOT," followed by a box containing four numbers, such as 1417, which indicates the tire was produced in the 14th week of 2017, while 2415 means the 24th week of 2015. When replacing new tires, it's best not to choose tires with a production date older than two years, but there's no need to insist on the very latest date—tires around one year old will not affect normal use. Choose the Right Tire Tread: Tires from the same brand also come with different tread patterns. The tread on a car tire not only provides grip and drainage but also enhances wear resistance and reduces noise through different tread designs. Car owners can choose the tread pattern based on their needs.

What does it mean to cross the line in the reversing test of Subject 2?

Crossing the line means the vehicle body exceeds the boundary lines. In the Subject 2 driving test, if the vehicle body crosses the line, 100 points will be deducted, resulting in failure of the current test. In addition to crossing the line, other actions that will deduct 100 points include failing to fully enter the parking space during reversing, stopping midway, not following the prescribed route or sequence, and exceeding the time limit. The full score for Subject 2 is 100 points, with evaluation criteria set for failure, deduction of 20 points, 10 points, and 5 points. The test is considered passed if the following conditions are met: ① For applicants of large buses, tractors, city buses, medium buses, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. If a candidate fails the Subject 2 test, they are allowed one immediate retest. If the candidate does not take the retest or fails the retest, the current test session ends, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of test appointments for Subject 2 and Subject 3 road driving skills tests must not exceed five. If the candidate fails the fifth test, all previously passed subjects will be invalidated.

What does it mean to cross the line when exiting the garage in Subject 2?

Crossing the line refers to the vehicle body going over the designated line. In the Subject 2 driving test, if the vehicle body crosses the line, 100 points will be deducted, resulting in failure of the current test. In addition to the vehicle body crossing the line, other actions that will result in a 100-point deduction include failing to park properly in the garage, stopping midway, not following the prescribed route or sequence, and exceeding the allotted time. The full score for Subject 2 is 100 points, with evaluation criteria set for failure, 20-point deductions, 10-point deductions, and 5-point deductions. The test is considered passed if the following conditions are met: ① For applicants of large buses, tractors, city buses, medium buses, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. Candidates who fail the Subject 2 test are allowed one immediate retake. If they choose not to retake or fail the retake, the test is terminated, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of scheduled attempts for Subject 2 and Subject 3 road driving skill tests must not exceed five. If the fifth attempt is still unsuccessful, the passing scores of other previously passed subjects will be invalidated.

What's the matter with incorrect exhaust camshaft assembly?

In this case, it is necessary to inspect the engine's variable timing system, specifically whether the oil solenoid valve of the VANOS system is functioning properly. Check the solenoid valve's resistance value, wiring, and whether the solenoid valve spool is stuck. If stuck, try cleaning it! Additionally, inspect whether the exhaust camshaft position sensor is working correctly. If necessary, examine the electronic valve system, namely the VALVETRONIC system. Introduction to Camshaft: The camshaft is a component in a piston engine. Its function is to control the opening and closing actions of the valves. Although in a four-stroke engine, the camshaft's speed is half that of the crankshaft (in a two-stroke engine, the camshaft's speed is the same as the crankshaft), its speed is generally still very high, and it needs to withstand significant torque. Therefore, the design requires high strength and support for the camshaft, and its material is usually high-quality alloy steel or alloy steel. Camshaft Structure: The main body of the camshaft is a cylindrical rod approximately the same length as the cylinder group. It has several cams mounted on it to drive the valves. The camshaft is supported within the camshaft bearing holes via camshaft journals, so the number of camshaft journals is an important factor affecting the camshaft's support stiffness. If the camshaft's stiffness is insufficient, it may bend and deform during operation, affecting the valve timing.

What is the inventory turnover rate for new cars?

New car inventory turnover rate is generally around 70%. A higher inventory turnover rate indicates better sales performance. Increase or decrease in inventory: Under the conditions of material shelf life and capital allowance, the inventory control target days can be appropriately increased to ensure reasonable inventory. Conversely, the inventory control target days can be appropriately reduced. Calculation formula for inventory turnover rate: The commonly used inventory turnover rate = Annual cost of goods sold / Average inventory value for the year. The annual cost of goods sold (COGS) (excluding sales expenses and management costs) is used as the numerator, divided by the annual average inventory value.
