thank you for the offer.
Through my research I've found that the original twitchy throttle (a leaner throttle mapping) in the 2006-2008 models led to slightly better fuel mileage in the high 30s, then in 2009-11 with the ECU remap to fix the twitchy throttle (richer throttle mapping in low rpms) the mileage dropped down to the low 30s. Then in 2012 there was another adjustment to the ECU to bring up the fuel mileage to the mid 30s.
I've noticed that I'm in city traffic a lot and on deceleration from around 50-55 in third gear at around 4000 rpms, I'll still get the AIS popping, which means there is just wasted fuel in the header. I've even tried lugging the engine and still get the popping. I dont' think lugging the engine way down is the right thing either because the whole purpose of an efficient internal combustion engine is to generate the most force (work) to the wheel with the least amount of internal resistance. I've tried shifting up a gear for the city and one I don't feel safe as I feel the responsiveness can't get me out of the way of the idiots and two I didn't notice any difference in mileage. The only improvement in mileage I've ever had is when I just rode around on the freeway and it only incresed my mpg by 2-3.
So my thoughts at this point are to either do a PCV(ex) with a better fuel control map for city riding and fuel mileage, increase the spark to help burn that wasted fuel or find a second bike like a BMW G650GS (my buddy gets 50-60 mpg) and commute on that.
