Yes, it is possible to retrofit an older motorcycle like a Kawasaki W650 with fuel injection from a modern Triumph Bonneville or another compatible system. Retrofitting fuel injection to a carbureted motorcycle can offer several benefits, such as improved fuel efficiency, smoother throttle response, and better overall performance.
Here are some key considerations:
Compatibility: The first step is to ensure that the fuel injection system you plan to use is compatible with your motorcycle's engine. This includes factors such as engine displacement, configuration, and electrical system compatibility.
Parts Availability: Check if the necessary fuel injection components, such as the throttle body, fuel pump, sensors, wiring harness, and ECU (Engine Control Unit), are readily available for your motorcycle model. It may require sourcing parts from the donor motorcycle or aftermarket suppliers.
Modifications: Retrofitting fuel injection typically involves making various modifications to the motorcycle. This can include modifying or replacing the fuel tank to accommodate the new fuel pump and fittings, installing the throttle body and associated sensors, integrating the wiring harness and ECU, and potentially modifying the intake and exhaust systems.
Tuning and Mapping: Once the fuel injection system is installed, it will need to be properly tuned and mapped to ensure optimal performance and fueling. This may involve using a dynamometer and specialized software to adjust fuel delivery, ignition timing, and other parameters.
Expertise and Resources: Retrofitting fuel injection requires a good understanding of motorcycle mechanics, electrical systems, and fuel injection technology. It can be a complex project that may require specialized tools, technical knowledge, and access to a workshop or experienced professionals for assistance.
Before undertaking such a project, it's advisable to research and consult with experts or experienced motorcycle technicians who have knowledge and experience in retrofitting fuel injection systems to motorcycles. They can provide guidance, offer advice on compatibility, and help ensure the retrofit is performed safely and effectively.
