We have a 2008 R1 stock motor in the sidecar.

Running stock computer and wiring.

The airbox variable velosity stacks have benn removed(plugged in to fool computer).

Is there and thing we should do to the harness to make the motor run better. Like remove,jump or cut out the speed sensor?

Dyna ignition?

Cant afford the yec parts.

Thanks

Paul

We have a set or FCR's(41mm) off the old R1 motor, but thought the fuelly was faster(more HP).

put the airbox and the stacks back on- it will run like shit without them- you will never be able to map it properly
