I'm quite surprised that after a couple of AFXIED comments, no one has popped in and suggested a BoosterPlug...

I added one to my '04 R1150GSA and it seemed to cure a lot of hiccups and lean stalls. When I got my (new to me) '15 GS LC, that was one of the first things I got, based on that previous experience.

The BoosterPlug is designed to make the air/fuel ratio slightly richer at idle, low RPM and during acceleration and deceleration to make engine run like you would expect from a premium motorcycle.

LOL...and yes, I've had my share of stalls too! That usually occurs when I forget what gear I'm in as I'm rolling up to a stop sign or red light (not noticing with my head on a swivel attempting to watch for traffic) and then try and take off in 2nd...or occasionally 3rd! 😒
Did read up a lot and the common consensus was the on LC bikes the booster plug would eventually stop working......but on previous bikes it really heelped....so i went with the AFXIED

Huh...where did you find that info, Virc? I researched a lot before I bought since this was my first LC bike and didn't find anything to that degree. Another search after you posted and I still don't find any mentioned issues.

Can you point to some links, please?
 
I have a BoosterPlug on my 2017 GS and it works well to improve low speed throttle response and torque. Yes, it still works the same after 6,000 miles - don’t listen to people who pass along false claims. The AF-xied probably works well, too. Hill Start also complicates things, so check the dash when stopped (which also tells you if you’re in first).

Since the BoosterPlug only helps during throttle adjustments, increase the throttle gradually during a launch for maximum benefit. If you open and hold a fixed throttle setting, the O2 sensor will take over.
