Yep, that sounds right. Been riding around on mine all morning and on the whole it definitely feels better than before the update. Power delivery is smoother and more linear from 3k upwards. The only thing that seems worse is the engine vibration is more 'buzzy' now and doesn't feel so smooth when decelerating. It also pops on the overrun now, which it never did before.
I'm liking the new fan operation. Most of the time it still runs a little at shutdown, if at a lower speed, so I still get that Buell experience.
Incidentally, I've been reminded how critical suspension setup is on this bike. A couple of weeks ago I slackened-off the front compression damping to try and make the bike less 'stiff' over rougher roads, but the bike felt dreadful, dangerous even. Adjusted it back and it's amazing how this transforms the handling and cornering confidence.
