RE EFI: My understanding is that EFI is mostly to meet governmental emission requirements. EFI improvements in performance are measurable at high altitudes. EFI improvements may - or may not - be measurable at very low RPM where atomization can be better with EFI. That said, without government interference, carbs are the choice of virtually all racers in virtually all races. They are my choice, too.
Has anybody done a side-by-side conversion test?
I invite you to take a look at the most recent Chapter in streamlining a
Ninja 250 We have the body and tail complete. Alan Smith, the owner / builder is putting miles on it as I write. I will report his observations.
I also invite you to meet us in Las Vegas, Nov 20, 9 AM Sunday at the Las Vegas Red Rock Casino for a little 160 mile test of the road to Barstow. We can get to know each other over Chinese food after the ride.
