Title: Forgot how much performance improves in warm weather!
Post by: kcoplan on May 06, 2014, 02:49:02 AM
Just rode to work in the bright sunshine -- nice to have warm weather after riding most of the winter.  I forgot how much the cold saps these bikes' performance.  Got the acceleration back -- and when I opened it up on the highway I was surprised to see the speedo hit 97 (this is on a stock '13 S ZF6).  Now, I know the speedometer on these bikes is a little optimistic, but still . . .    ;D

The ICE biker I passed never heard me coming.

Meanwhile, my wife's '13 XU is operating erratically again (sometimes it runs on bootup, sometimes it doesn't).  The dealer didn't really fix it -- even with all the logs they had no idea what the problem was and just plugged it back together and hoped the problem was a loose connection that would go away. It didn't.

I have checked the speedometer on my 2014 S and it is spot on, which is a big improvement from the speedo on my 2012 S, which was off by about 8%.

Sorry to hear about your wife's XU.  :(   I hope Zero can solve the problem and your dealer will fix it for her.

Karl, did the shop check the connectors going into the bottom of the DC-DC converter? Dunno what they're like on a 2013 XU, but on my wife's 2012 XU they're kinda dicky. I could see them being loose connections that would make trouble.

Peter, I don't know what they checked, specifically.  I was told they disconnected and reconnected the main bike board to do the firmware update, and they hoped that that resolved any loose connections.
