The new 2004 6rr model is stronger in lower rpms than the 2003 6rr because of finer fuel injection.
I own 03 6r so I wonder is it possible to mount only 04 6rr fuel injection on my bike to gain a few horseys and in the same time optimise fuel consumption?
You would have to adjust many many settings to do that on your bike. The 6R has a 636cc engine and the 6RR has a 599cc motor. You'd be better off changing your exhaust and remapping your FI to gain those HP.
