I find that in Street mode, there is a bit of slack before the throttle actuates, but in Sport it is not a problem.
TBH, for me, this is the main difference between the two modes.

I actually think that the sport mode produces a smoother throttle feel, across the entire range. This is what I am riding now.

I ride because my wife says it keeps me young and is better than if I get a girlfriend...

Hmm - interesting. Can't say I've noticed it - but I leave mine in Sport now.

Thanks. I will be doing this mod. I always have tight throttle cables and hate the sloppy throttle play on 790

First remove your bar-end and then remove the two screws on the bottom of the control unit. Luckily for us, we don't even need a security bit to do this mod like the Ducati guys do.

Remove the top of the control unit and you'll be able to slide the grip straight off.

Now find yourself something to use as spacers approximately 1mm in thickness. I used the plastic off this wire tap I had laying around.

Cut the spacers to fit on the grip like this and use some super glue to secure them in place. Test fit the grip on the control unit and (if needed) file the spacers down so it fits snug. If you prefer a little play, you can file this to your liking. I have mine set with no play at all.

Attachment 1834

Re-assemble everything and test it out. Bike should idle just like it did before and the grip should turn smoothly throughout its range of motion. Enjoy a less sloppy ride!

Great post! I haven't collected the bike, but similarly I usually run pretty little free play on the throttle. Will definitely be doing this!
