Thank mrcrunch! No offense taken. I've focused on aero, gearing and riding techniques as they are the easisest and most effective areas for big improvements. I agree that motorcycles are pretty crude in engine management technology compared to cars. I don't see myself investing in FI for this bike as the current systems available haven't demonstrated a large enough improvement in fuel economy ( if any ) to be worth the investment IMO, particularly for this low budget project. I may play with the ignition timing and camshafts in the future.
Going with taller gearing makes the 250 Ninja a much better streetbike IMO with improved freeway cruising and fuel economy, the only down side is a slight decrease in maximum acceleration.
In the near future I think we will see more sophisticated 250 cc bikes with efficient FI. The Honda CBR250 is a start, now will Kawasaki meet the challenge with a redesigned Ninja 250?
