Why Does the Idle Speed of an EFI Motorcycle Fluctuate?
1 Answers
The reasons for fluctuating idle speed in an EFI motorcycle are: 1. Carbon buildup in the throttle body, leading to blocked air passages; 2. Low fuel pressure or intake manifold leaks; 3. Sensor malfunctions. Issues in the engine's intake system, fuel system, or ignition system can all cause unstable engine speed, requiring a detailed inspection at a repair shop. An EFI motorcycle is a new type of motorcycle that uses a microcomputer to control the fuel injectors, supplying fuel to the cylinders that need to work while cutting off fuel to inactive cylinders. EFI motorcycles only allow the use of 93 octane or higher unleaded gasoline. The motorcycle's horn should not be installed near the ECU, as the magnet in the speaker can damage components inside the ECU.
