I'm really starting to get the tune dialed in. I have great throttle response, and steady AFR's throughout the fuel map. Once its a little more dialed in, I will work on the cold running conditions. In addition, Phil Tobin, the guy who wrote the tuning software, is going to be debuting an auto-tuning algorithm for warmup variables.
On a ride I took this evening, at constant 70 mph, I am getting about 50 mpg instantaneously, with an AFR of 15:1. I still have room to go as it is running smoothly with no misfires, and I can probably dial cruise AFR back to about 15.5-16:1. Something around 55 mpg (US) at 70 mph is definitely achievable, which is quite good for an unfaired (except windshield), undergeared, shaft driven, bag equipped, standard with 100k miles on the clock.
Once I get the cold start tuned, It will be a very feasible and useful upgrade for others. I will have done 95% of the testing, research, work and trial and error involved, and will set up a cohesive set of documentation here once I settle in on a final configuration.
