With the fi bikes, learning to roll the throttle on and off is a technique that must be learned if you want to ride smoothly. Carbs had over lapping systems, low speed jet > pilot jet > main jet which made trasitions of throttle smooth. Fi has no overlapping systems so it's either on or off. The smoother you are with the rolling on and off with the throttle the smoother the bike will react to inputs.

This is exactly what I had to learn when I got my CB900F (919).
It was the first FI bike I had ever ridden and it was a nightmare for most of that summer riding in traffic; sudden on, sudden off, sudden on, sudden off.
It was a wonderful bike out on the road, but at the end of that first summer I thought I had made a great mistake and began to regret buying it because most of the time it was so herky jerky riding through the city in stop and go traffic.
The following summer something clicked immediately in my pea brain and I suddenly became an old hand with the FI and have had no problems since - and I still have that bike.
Except for the 1100 all my other bikes have carbs and when I switch rides back and forth the transition is quite easy.
But I will say that the FI on the 1100 is so much more refined than the 900F and adapting to it was very smooth.

I actually sold a couple of bikes because the EFI was so bad. But it was in large part because I had not learned to adapt to it. Very different riding style and throttle control needed.

This is specifically about picking up the throttle from the bottom of a turn at max lean, the EFI had a disconcerting jerk and after years and years of carbs, I just figured the EFI was badly sorted.

Now I know "they all do that."
