Ran the bike over to the dealer. They found no faults.
Going to be in Alpine again this weekend. I'm going to take a video of the start.

As promised above, here is a link to the video of a 30 degree start.

I noticed several other K16 bikes on the ride had similar issues on cold start up. So, maybe mine is not special.


Isn't there usually a cold start procedure in the ECU that basically floods the injectors with gas on a cold start? Is this maybe a EURO 5 emissions issue?

Still sounds like it's missing on at least one cylinder to me, when she does decide to start - presumably producing full power once warmed up?

Back to the dealer with that vid I reckon for a bit more research, as I suspect they simply relied on standard diagnostics.

I think it the Lithium .


Cold bike with cold battery is going to draw more amps to get it to spin quick for it to catch, bike has an external temp sensor, and probably has altitude sensing as well, so maybe the map is off for the particular environment.


Does ethanol have cold weather issues, does it thicken

Lithium batteries need a couple of cranks to actually warm up the battery then they provide closer to normal temperature cranking amps. Just one of the downsides to the long storage charge they have and light weight.

Ethanol attracts water vapor and if it sits will separate. At that point it is an issue in very cold weather, but not an issue if you are going through at least a tank a month. Just short term 30 degree temps are not likely to cause an issue with water in gas freezing. So highly unlikely ethanol has anything to do with it.

I couldn't listen to the video because I'm at work but why did you open your gas cap before attempting the start? Also, what battery do you have installed. I read someone above mention a lithium battery.
I don't have any cold starting issues and have crappy ethanol gas in my area as well. I have a Odyssey PC680 battery and have had nothing but good luck with it.

The dealer didn't find any fault codes. So they blamed the fuel cap, suspecting it isn't venting. So I opened the cap to be sure it was vented. The video is for the dealer.

@Jonnybow @woodbutcher I mentioned LITHIUM, its the radio station on the dash wondered who would notice

If you had ridden 60 miles from a full tanks and got to a negative pressure issue then maybe that would have helped, I have a bigger pile of straws they can clutch at
