Why is the motorcycle lacking power?
1 Answers
The reasons for a motorcycle lacking power are: 1. Fuel supply system issues, clogged air filter, or a carburetor that hasn't been cleaned for a long time can lead to decreased engine combustion efficiency, with severe cases even causing black smoke from the exhaust pipe; 2. Engine faults, such as normal wear of the cylinder and piston rings, artificial damage, clutch slippage, incorrect valve timing, or excessively small valve clearance. The working principle of a motorcycle engine is similar to that of a car engine, with most motorcycles equipped with a four-stroke engine. A four-stroke engine operates in four strokes: intake stroke, compression stroke, power stroke, and exhaust stroke. Scooter motorcycles do not require gear shifting, whereas straddle motorcycles do.
