Motorcycle belt noise can be caused by the following reasons: 1. Severe wear of the variator rollers. 2. Slipping phenomenon: When there is slipping between the clutch shoes and the clutch bell, remove the clutch bell and inspect the friction surface. 3. Aging: If the motorcycle has a kick starter, over time, the two shafts and sleeves of the kick starter may develop play. The engine vibration is transmitted through the kick starter gear to the shafts, causing knocking between the shafts and sleeves. 4. Timing chain stretch or tensioner failure: Large valve clearance or wear between the valve rocker arm and camshaft, slight scoring between the cylinder and piston, or increased clearance due to piston skirt wear, and issues with the oil pump chain (if applicable).

How to Use the S Gear in Volkswagen?

Volkswagen's S gear is typically used when high torque is needed, such as for climbing hills or quick overtaking. When the gear lever is in this position, all forward gears will automatically delay upshifts and advance downshifts based on engine load, individual driving style, and vehicle speed, making full use of the engine's power reserve to provide higher torque output and acceleration. Starting from 2015, the Volkswagen brand will gradually introduce a new engine torque-based rear badge system in the Chinese market. One of the core competitive advantages of Volkswagen's engine innovation technology is its torque performance. The TSI turbocharged direct-injection gasoline engine can generate greater torque without increasing engine displacement and maintain maximum torque output over a wide range of engine speeds, which better adapts to China's unique traffic conditions.

What's the reason for the sound of metal friction when stepping on the accelerator?

If this situation occurs, it should be due to carbon deposits in the intake system. Below is extended information about carbon deposits: 1. Introduction: Carbon deposits include two concepts: One concept refers to engine carbon deposits, which are a kind of coking substance produced by unsaturated olefins and gums in fuel under high temperatures during the engine's operation. The second concept refers to carbon deposits in electrical discharge machining, where carbon deposits should be avoided as much as possible, especially in precision mold processing, as they can have fatal effects. 2. Causes of formation: Carbon deposits in the combustion chamber are caused by tiny carbon particles produced after the explosion of gums in gasoline components and hydrocarbons that cannot be completely ignited. These black particles should be discharged into the atmosphere with the exhaust gas or accumulate on the muffler pipe.
