Norge TB sync - how difficult?

Pete, forgive my ignorance. I went riding again today, central Illinois, around 45 degress, mpg has fallen to around 38 on most recent rides per Breva gauge. Define "ETS'" and your packing recommendation. Greatly apppreciate any enlighment.

On a recent trip to northern British Columbia from southern California on my '08 Sport 1200 I noticed that temperature affected fuel milage more then anything else. When the termometer dropped to freezing my fuel milage dropped to 35 mpg, from 42-45. The bike did run better the colder it got; smoother and more responsive. As it warmed the mpg increased. Altitude and aggressive riding seems to have little affect.

My experience with my 07 B11 is identical to yours Allan. I love the way the bike runs in cold weather.
 
There's another, unavoidable reason why cold weather gives higher mileage. Cold air contains more oxygen. The ECU is supposed to be able to detect that, and adjust the injection to avoid leanness. I don't know how noticeable this would be on the mileage, and one would assume that there wouldn't be any change in throttle response if the ECU does its job correctly.
I've read yet another explanation why air-cooled engines burn more fuel in cold weather, but can't recall what it was.

It's true that the bike changes a lot in colder weather. Mine ran great yesterday on my regular trip to the country-side, her pilot less so though (left late after a long day, 't was dark and he hadn't really registered what 0ºC would mean...) A shame for all those people who only see temps under 10ºC in their fridges! :silly:
 
Of course, whet I don't know is whether he reset anything else while he had the Axone connected. He did check that the Lamda sensor was working, as that failing could cause my problem.
Pretty well all infernal combustion engines use more fuel in very cold weather in my experience.

Out of interest I connected my vacuum guage to the Norge when I got home yesterday. It's a water U tube type, home made. It did show a difference of about 3 inches left to right. What did surprise me was that when I stopped it, then went back a couple of minutes later and tried again, I got different results.
In fact every time I resarted, the slight difference changed sides. I made no adjustments.
Up to 3 inches of thin oil (I put in auto transmission fluid, not water in the U tube) however, is very little on a mercury guage.
 
I'll re-raise an issue/question though, in hope Pete reads it.

Ever since its 10k km service, my bike has some difficulty starting when it's under about 7ºC. She starts fine, but there's an initial time lapse of varying duration where she won't hold idle over about 800rpm. Depending on the temperature, the engine dies either after some struggling, or immediately. Yesterday, I had 3ºC on the dash, started, she died. Started again, opened the throttle immediately and held her at 2krpm for a while, periodically closing the throttle carefully to see if she'd "take over". After about 30s I got "bold" enough to keep the throttle closed, and saw the needle go from about 800 to 1200 (and could finally put on my gloves :) )

It's possible I could have let go of the throttle sooner, but as it was, it's just too long to be something I'm happy to do every time I start on a cold engine. Funny thing is, she never did this unless temps were really under 0ºC BEFORE the 10kkm service, and then she had 15W50 oil in the sump (10W50 now).

What could this mean in terms of adjustment? I don't see how the ETS (2laner: engine temperature sensor) can be involved (engine and air temp are identical on a cold start). The oil used in the gearbox? (don't see how, with a dry clutch, pulled in according to the book)
