Thruxton R
Hello, I have a 2016 Thruxton R with 3500 miles, I am the 2nd owner, got it with only 1500 miles.

Yesterday a couple of friends and I got caught on some suburban roads with stop and go traffic, with nowhere to go and the roads being so narrow that we could not filter around the massive line of cars. It looked like many streets were closed which caused an insane amount of traffic. I could feel the bike being hot but did not had any indicators popping up (I replaced the coolant fluid about 1000 miles/6 months ago).

The point is that, once we got to our destination, we did what we had to do and 30 mins later as we were leaving I felt that the Thruxton was behaving oddly at slow speeds when leaving the parking lot, the engine stalled after a few feet.
I turned the bike back on with no issues and that is when I realized the idle revs were lower than 1K rpms, and when I applied the same amount of throttle I normally do the bike would stall again.

Since I was in a rush to get home and didn’t see any temp or engine indicator I just proceeded to turn the throttle a little more to avoid stalling. At speed I did not have any issues, I went straight home and varied my speeds from 40 to 80 mph on my 20+ miles to home just to see if I found any lack of power or other issues, could find any additional issues.
I live Downtown so once I got into my city, I had to stop for a bunch of lights, the low rpm issues came back as soon as I got the first light so I kept the revs a little higher than usual.
As I made my way home, I noticed that by the 3rd or 4th light, the idle issue disappeared and the idle rpms were back at 1K.
I am in the DC area and the temps yesterday were in the 60s so it was not overly hot (thank god).

I am thinking that due to the “smart ecu” that these Bonnies have, the stop and go traffic really made the engine run really lean and it corrected itself once I entered normal riding conditions.

What do you think, would that be a somewhat correct guess?

? Good question, did you check your cooling fluid anyway?

There is a warranty remap on your bike that may or may not have been done that is supposed to help with the stalling issue .I have experienced the stalling under similar conditions but not the low rpm issue . Have yet to get mine updated , COVID Travel Issue , so will be interested to hear your future report . Since the decat install it has happened much less frequently .
