Cold start stalling

[Grumpy Goat]

GG, the bike is a 2020 1250 with 7500 mi, I purchased it new in Feb 2020. Yes the bike starts right up and then stalls and takes some playing around with the throttle to keep it running. Bike has a fresh battery and lives on a battery tender in the winter. No codes on GS911. Never had this problem before last fall (thought the new battery would cure it, but no).
Lee, warranty ran out 6 days ago  , plus nearest dealer is 300 miles away...
Thanks for the replies

Chris - thanks for the additional clarifying info. Sounds like it needs some sort of tune up of the fueling and/or emissions system. Battery would not alleviate such a problem, but plugs might and that is the easiest thing to check and cheapest to replace. Even if that doesn't cure it you still have a second set.

Do you periodically use fuel system cleaner like this? I do (when I remember) and I believe that it keeps the crud at bay (I say "believe" because I personally have no specific experience either way to say they work or don't work). That is another cheap thing to try. To reduce the time for solving this issue, if I were you, I'd do this even before the plugs (which should still be OK at 7500 miles).

Also, try different gas - I once filled up the tank for my Yamaha - from an Exxon station no less!! - and it ran like sh*t from the get go. Next fill up it was fine, as have all the fill-ups from that station (one of my regulars). I also bought gas for other vehicles from no-name pumps and had similar sh*t running experiences. So, I only buy so-called Top Tier gas (usually from Exxon) for my vehicles - all of them. The RS (at least mine) is *very tolerant* of what you put in it, and I am sure it would burn kerosene if you put it in.   I have only used mid-grade in my bike (as I refuse to use Premium on a regular basis - I am too cheap) and occasionally when on a long trip I will use Regular, and the RS does not complain or run any differently.

If none of these work then you may want to relent and bring it to the dealer for more intrusive troubleshooting using proper diagnostic equipment. These bikes have lots of systems and electronics to deal with emissions requirements and it could be that something undetectable to the customer is slightly off.

Warranty should not make any difference if it is tuning issue - you should still have to pay for the work done.
