Default NOT starting?

So my 2017 ultra limited low, love this bike--- I'm short. I have had a few thing go wrong with it but over all its a great bike. I have a new one(problem) that I'm just having a problem with the fix I got from the dealer. I took the bike to work the other day and it was cold, like 22 without the wind chill. I live in Newport news VA, that is cold for us. I ride this bike all the time, work or play. I went to come home and the bike wouldn't start. It tried to but never did fire up. It turned over, just no fire. I went home to get the trailer, loaded up and parked it on the trailer in the garage. I put the tender on just for the hell of it, thinking the battery may have been low from the cold???? 2 days went by and tender says its good. I still couldn't get it to fire. Oh just so you know this bike is stock. I took it over to the dealer after that and dropped it off. I get a call and they said it was the plug wires were all bad???? Hmmmmm I didn't get any feed back from the bike on the way to work at all. The bike ran like it always does, great. They didn't have these in stock, they did have SE brand in stock. I go to ride the bike home from the dealer and get a check engine light, they had gotten it also but cleared it. I went back and they told me after them having it to ride it it was only a P0131 and it may clear itself. I picked it up again and they said all is well. I came home and parked it for a few days, weather. I pulled it out today and went to the bank/hair cut place. The check engine is back on again and now the radio is not work as it should. I do take the tour pack off when I'm alone going to work. In fact it stays off most of the time in the winter.

Ideas????????

see if I got this right, wouldn't start several times, they said bad plug wires, replaced them and it has started ever since
P0131 code:
'P0131 is telling us there is a fault in the oxygen sensor, located in the bank 1 sensor 1 location of the vehicle. This is also called air/fuel sensor, or heated O2 sensor. This means that the ECU has detected either improper voltage from the oxygen sensor or improper air-fuel ratio.'

take it back and make them fix this mess since the radio is suddenly "now the radio is not work as it should"..they need to take it more serious and dig deeper imo, good luck

Also, another thing to check, look at the battery cable connections...ensure they're "both" tight ad "both" ends. Loose connections can cause all kinds of trouble.

Truly. Those battery lugs work loose. Must be the soft lead. I re-torque mine every couple of months, and they are always surprisingly loose.

But if somebody told me I had four, count-em four bad spark plug cables at the same time, I'd be real doubtful about that.

ing, would look better at the end of work. So they picked up the bike, we'll see what comes out this time.

If it does not start and you keep trying it will throw codes. M8 do not like cool. 1 battery needs to be up. If you try to start and it fails Stop. Roll Throttle all the way open. Be ready to roll off when it starts. Starting when it gets down to 10 degrees requires you do it right or not happening.
Of course there can be many reasons a bike does not start so try the above see how it works for you.

After I swapped the cam I used the Power Vision from Fuel Moto. Did some auto tunes and things were fine until the first time I went to start on a winters day. Cranked fine but no start. Quickly learned that if I held the throttle in clear flood mode ( wide open )it would fire. Contacted FM who sent me another tune and that cleared the issue. In FM’s defense they hadn’t worked out a tune for the particular combo I used, so no grudge there.

You didn’t mention if there were any mods, so all of this may not apply to your situation. I’m only suggesting that if the condition reoccurs you try going full throttle and see if it helps. Also be specific - there’s a difference between not starting and not cranking, and letting the service dep’t know could save some confusion.

Luck!
