R1200R cold start (or non-start) or: Consumer reports broke my BMW!

As if in perfect sync with the BMW reliability thread, my R1200R felt like a lazy bastard this AM.

Cold start (thermo showed ~33 degrees). Engine cranks and turns over for half a second, then dies. Count to ten.
Repeat.
Repeat.
Repeat.
Repeat, only I have to hold the starter longer.
Last try: Hold throttle partially open and engine cranks, revs to about 2.5-3k, then holds at "normal" idle, and is more or less fine for my commute.


800 miles on the bike, Just had the 600 mile service yesterday (roh roh!). Is this a fluke, some sort of cold idle setting that is borked, or are these boxer engines just sluggish as hell when cold? It has seemed to want to stall for the first few minutes on cold mornings like this and takes a little extra throttle, but it has never died immediately after cranking like this. It has cranked about 8 degrees colder with no issues pre-service, other than being sluggish and wanting to stall until warm.

Weird.
Did they dork with your throttles during the service?

My 2011 did the same thing when it was <40 degrees out when I first got it. It had a little over 4,000 miles on it at the time I bought it. I had to add a little throttle for 5-10 seconds before it would idle on its own after starting in those temps.

I've since installed a BoosterPlug and I don't seem to have that problem any more.

My rt and neighbors gs do not want to start if temp get below 35. We almost need another batt before they light up. We both have new batt and have tried cracking the throttle. Another buddy with a gs in co has the same issue.

Was fine this AM, so I guess it was just a bizarre fluke.

I've been riding every morning this month (which, in case you're under a well-heated rock, has been cold as fuck). It gets hesitant when the engine is cold, but never as bad as yesterday, and it always fired right up. Really, it acts/acted like a cold carbed engine when you forget to use the choke.

I guess this is all part of that "character" boxers have I keep hearing about
