Fault Finding – Non Electrical
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 |
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 | |
Diagnostic software malfunctions during tune download procedure | Low battery voltage |
Throttle hang-up | Incorrect closed throttle position setting |
Motorcycle will start but cuts out immediately | Low fuel pressure caused by loose fuel pipes to the fuel pump and filter |
Low fuel pressure caused by filter blockage/leaks | |
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 Thermostat fault |
Motorcycle will not start | Check the immobiliser system for faults |
Make sure that the keys, Engine ECM and Chassis ECM are all correctly paired |
