Sudden decrease in gas mileage

[Popeye the Sailor]

Dude, that's a 15% drop...

I don't know about you, but I can get 40's with just day to day riding and almost half that when I flog it. All we know is it's being ridden harder, not how much.


He did say "It's running great otherwise - lots of power where I need it, nice and smooth at lower RPMs, no lurching at all. ", and just in my humble opinion, if it's working well, I don't mess with it.

Well, the problem appears to have solved itself.  Last 3 tanks were 40-42 again, just slightly lower than before, and I've been flogging it hard .  (For you So Cal boys, we did the 33 yesterday, and it was gorgeous and dry the whole way - we took a spirited approach to the opportunity...)

So, I don't know what happened.  I never did reset the ECU since it changed right when I was about to do so.  I think it was a temperature/elevation shift that just took a while to work itself out.  Strange though.
