When I picked my bike up from the dealer, they hadn’t had the bike on a battery tender, and although it was showing decent charge, when they started it, it did the standard KTM cold start warm up idle issue until warmed up.

I did a bit of reading around and figured between the Heavy crank, Demands of the EFI and draw of initial spark that this bike may be sensitive to a fully charged battery, down to fractions of a volt.

Since owning the bike I put it to bed every night with a battery tender on and never had any cold start idling issues and always a strong start the next day. I just routed the dongle to be accessed without removing the seat.

this thread is to encourage those with start issues to try this and I’d be curious to hear results.

I am also running exclusively chevron 94 (aki) no ethanol gas.

I would be curious as to what firmware version is your bike has currently? (Menu/bike info/service) at the bottom of the screen. I'm 95% sure that v5.20 is the latest. I think this version may fix this issue though software mapping, but could totally be wrong also...

I do not have a cold start issue with the Norden but my 890 Adventure still does. I figured they had improved the cold start mapping and was going to bring the 890 in to see if there are updates available. I will try leaving the tender on the 890 to see if there is any difference. I do know that if a battery is not charged to 100% when new it will often have issues even if charged to 100% later.

I'm testing your theory tonight on the 890 Adventure. It started like pooh today, was running on 1 cylinder for a minute. Figure perfect time for a test. Will let you know what tomorrow brings.

"Update* After thinking a software update fixed this issue, software version 5.20 did not help, I still get the cold start issue 1 in 3 starts and it's definitely running on one cylinder for 20sec or so when it's cold about 60% of the time. Sometimes it dies. I've noticed that giving it a little throttle to about 2k rpms when I start fixes it even if I just roll on for 2-3 seconds. Shitty that I cant just hit the button on a fuel injected bike and have it reliably start.

I just read on Adv forums that Rottweiler found a fix for the 890 cold start issue and it has so far worked for me. Turn the ignition key on, emergency switch off, Kickstand up, (just like you would regularly start the bike) listen for the fuel pump to kick on then off (5 seconds or so) then turn the key off. Then turn the key back on and when the pump cycles and the pump turns off again hit the start button. It's worked 3x for me so far. My working theory for a "fix"...

A cool feature about the start button is you don't have to hold it, just pressing it once will cause the bike to start up. Like a press to start button. FYI

Funny you should post that. I was just thinking today that my 2011 Triumph Sprint GT had a similar starting issue and cycling the ignition key was the same fix for it. In fact I was waiting for tomorrow morning to try it. Sounds good to me.

Mine did this today, 3 degrees C outside, so first time I have seen this issue arise. I'll give the method above a crack. Thanks

Ok try this. My Norden is without issue but my 890 Adventure is hard starting so I've been brainstorming solutions with a really good tech at the dealer. I have tried cycling the key on and off, no difference. In fact I have tried everything written without results. Finally I seem to have discovered how to cold start the bike. Before hitting the starter button open the throttle just a little bit, hold it in that position and hit the starter. Bike will start first time. After a couple of seconds release the throttle and the bike will idle normally. I am only opening the throttle enough so bike runs about 2000 rpm. I do not wait for the bike to not start, I do this first try and so far the bike is starting great every time. Please let me know your results. Now that we seem to have a solution finding the cause will be easier.

Yeah, I probably should have posted again about this after these last couple weeks of frustrations... I've got the latest firmware, I've tried different 5 gas stations, I've done the cycle on / off / of "tricks" and have not had many issues until these last 2 weeks. It's been 95° outside (so it's not ambient temperature cold related) and my bike is kept around 75° indoors, but all week I've had issues starting. The only thing guaranteed to work has been to crack the throttle to about 2k a few times on startup. It died on me 3 times this afternoon and finally I gave in and blipped the throttle while pushing the start button and it stays running. The other day I thought to myself after starting without touching the throttle that is sounded just like my DRZ400SM thumper and then I realized that it was just running on one cylinder, I revved it up a bit and it sounded normal. When downshifting in hot conditions I get backfires when going downhill, even with the stock cat / can. I'm of the opinion as of late that the real issue is lean idle mapping and KTM / Husky has not addressed it yet. But this is just a speculation.
