So I officially put the Ninja 650 on the road today, and started creating the new fuel map using the Bazzaz ZFI, with the Z AFM autotune. The beauty of this system, is it records all AFR data to allow you to adjust fueling as you see fit. Well.... the outcome of what a Delkevic system will do to stock AFR's are a bit shocking. I knew the bike was going to run on the lean side, but this was a bit much for my taste. Have a look for yourself....
After seeing these results, I highly recommend a fuel controller for this system. In comparison, my Z650 with Yoshimura Alpha (pre Rapid Bike ECU) never broke out of the 14 range, while this system saw into the 16's.
