Single cylinders definitely have a sweet spot, even ones with balance shafts like ours.
You will get used to feeling it. The vibrations will smooth out and you will be right on the power band when you get it right.
This applies for any gear you are in. I'm finding I never hit 6th in town, even on some of our freeway sections. 55 mph, 5th gear, just over 5k.
Don't lug it and you can't really go wrong. These things like to be revved
