Fuel Pump Assembly
The internal electric motor within the fuel pump housing is prone to failure, often due to thermal fatigue or particulate ingress. When the motor fails to reach nominal RPM, it cannot generate the fuel rail pressure required to overcome the injector's cracking pressure. This results in a 'crank but no start' condition because the EFI system cannot initiate a stoichiometric burn without pressurized fuel delivery.

Lean Angle Sensor
This safety component is designed to kill the engine during a roll-over event. If the internal pendulum becomes lodged or the sensor fails electronically, the ECU will inhibit the ignition and fuel systems. The machine will continue to crank mechanically, but the software lockout prevents the engine from firing to protect the rider and the lubrication system.

NGK Iridium Spark Plug
Single-cylinder high-displacement engines are susceptible to spark plug fouling if the air-fuel mixture is rich or if the machine is moved short distances without reaching operating temperature. Carbon deposits on the insulator nose provide a path of least resistance for the high-voltage current, preventing the gap jump necessary to ignite the compressed air-fuel mixture.
