Symptom | Possible cause(s) |
Poor throttle response at low RPM | Low fuel pressure caused by filter blockage/leaks |
Low fuel pressure caused by loose fuel pipes to the fuel pump and filter | |
Cutting out at idle | Throttle bodies out of balance |
ISC (Idle Speed Control) actuator inoperative | |
Low fuel pressure caused by loose fuel pipes to the fuel pump and filter. | |
Low fuel pressure | |
Weak mixture caused by air leak at the throttle body/ transition piece to cylinder head face | |
Idle speed too low/high | ISC (Idle Speed Control) actuator sticking |
Incorrect closed throttle position setting | |
Mechanical fault with the throttle linkage | |
Diagnostic tool malfunctions during tune download procedure | Low battery voltage |
Throttle hang-up | Incorrect closed throttle position setting |
Bike will start but cuts out immediately | Low fuel pressure caused by loose fuel pipes to the fuel pump and filter. |
Low fuel pressure due to split fuel filter | |
ISC motor stuck | |
Abnormally high fuel pressure | Fuel pressure regulator inoperative. |
Temperature gauge reads cooler than normal | Cooling system air-locked resulting in coolant temperature sensor operating in air instead of coolant. |
