Random Stalling

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.
Thoughts?

Have they done all software updates to the ECU? As I remember there was a software update to fix this.

I don't know... I've had plenty of problems with the charcoal canister but stalling while decelerating was not one of them.
It was my only problem with it. It would happen 3-4 times a day. I removed it and it never happened again.

My 2013 would occasionally stall on decel - usually downshifting from higher gears - when it was new. I think an ECU update and canister removal solved it. Not sure which because dealer did both at same time.

Yes, all the service bulletins were taken care of, including software updates.

I think I will pull the canister off in the next few weeks. I want to use that space for a stebel horn anyway.

I stand corrected. The good thing is that it's easy to remove it and see if it helps, and to put it back on if it doesn't and you want it back.

Just out of curiosity, what engine mode were you in. I had this happen after some low speed stuff including clutch slippage off road. I was in sport mode. Don't know if it matters, but who knows.

I use touring. have noticed it also stalled under sport and urban.
