Normal for motorcycle to have a stubborn shift pedal/transmission when sitting for a few days?

My 1993 Honda Nighthawk 750 I sometimes skip days between drives. This time I haven’t driven it for a week. I always start in neutral and when I put it in 1st the bike died, which happens often when I first start it. So I started it again and dropped it into 1st but with a little throttle this time. I drove it in first gear and as usual, it wouldn’t go into second initially. I drove it in first for a minute and kept trying to shift to second. It took a few blocks, but then it started to shift into second. It seems it just gets stiff when I don’t drive it every single day. Is that usual?
After driving it for several minutes on main roads, the shifting was a breeze. And also I could shift out of neutral into first and it wouldn’t die. In an unrelated issues-The carburetor also responded better after fully warmed up. Usually the throttle has very sluggish responsiveness when I do a cold start and take offâ€Â"meaning I can hold the throttle halfway down and it takes off slowly…slowly.faster… a little faster. And finally up to where it should be with RPM.
These problems are always happening like it’s a warm-up sequence. Is it? Should I take it for repairs? I put in a new clutch cable and a new oil change which didn’t fix any problems, and I didn’t think they would. I think since these problems leave in five minutes, I don’t think it needs a shop.
