Can you make your 1998 CBR Honda 900RR Fireblade fuel injected?

This can be done but it requires mechanical skill and considerable costs. It is possible to get aftermarket stuff but basically you need the complete wiring harness, the instruments, an ECU, throttle bodies and sensors.

You will need a PC3 to tune your bike. It may be best to replace the intake manifolds also. The bottom half of the airbox fastens onto the throttle bodies, this has to be modified as you need to attach this to the bottom of the orignal airbox. The most difficult part of this job is mounting the different sensors as your bike does not have the fasteners for them. Some mixing of different parts, old and new, is required.
