Update: I've put in 91 octane the last few tankloads, and haven't heard any pinging. And, I swear this has to be wrong (I did lean out the jetting somewhat, but this is ridiculous...), but I got 52 MPG on the last tankful....not highway, just my usual 30-50 MPH backroads! I think I may have been a little easier on the throttle as I had just rejetted and was conscious that the next fuel stop would be interesting, but sheesh! Great if it's true.Strangely, ALL of my bikes have improved their mileage lately (maybe it's gas prices - a subconscious thing feeding from my wallet, through the cerebellum, to the wrist?) Almost makes up for all the gas I've spilled on the garage floor pulling float bowls to replace jets....
