Did you ever get this fixed? What solved it?Am hoping I can get some answers from fellow owners.
2013 821. I got it in March with ~700 miles.
Mechanically bone stock except for a GPR exhaust can I recently installed.
I noticed early on that once in a while the bike would stall as I decelerate to come to a stop (after I press in the clutch to downshift).
Took to dealer in May and they believed the AIS valves had carbon buildup, as they were giving wonky readings on the computer. they cleaned them up and all was fine for a month or so.
Now with 2,000 or so miles on the bike, am noticing the issue has returned and on every other ride, I will get the random stall. starts right up after stalling (fun to do as you are rolling and realize the engine died)
As I mentioned, no mechanical mods to the bike other than the GPR can (condition existed prior to installing it).
happens whether it is 40 degrees or 90 degrees out.
