What is the reason why a scooter cannot accelerate beyond 60?

[DelHaley]

The reasons why a scooter cannot accelerate beyond 60 are a clogged air filter and belt slippage. Below is relevant information about the timing belt: Definition: The timing belt is an important component of the engine's valve system, ensuring accurate intake and exhaust timing by connecting to the crankshaft and maintaining a specific transmission ratio; Function: The timing belt serves as a link between the upper and lower parts, connecting the timing pulley on the engine cylinder head at the top and the crankshaft timing pulley at the bottom; The timing pulley is connected to the camshaft, which has cams that contact small rocker arms. The rocker arms generate pressure from the power transmitted by the timing belt, creating a lifting effect.
