What is the reason why a motorcycle cannot start when in gear?

[GideonMarie]

Motorcycle cannot start when in gear for the following reasons: Idle speed issue: Sometimes it cannot start due to low idle speed. Normally in summer, the tachometer needle should point to one mark or slightly more, while in winter it should be adjusted to between one and a half to two marks. Spark plug problem: Replacing it can solve the issue. Sometimes the spark plug can be flooded with fuel. Check if the spark plug head is oily or wet, which can also prevent the motorcycle from starting. Cold weather in winter: This often leads to difficulty in starting. In the warmer climate of the south, unless there is a fault with the motorcycle itself, starting issues are rare. In northeast China during early spring or late autumn when temperatures drop below 0°C in the morning, the engine oil becomes viscous, making it difficult to start.
