Acceleration issues

Hi guys
I bought a few weeks ago an CB500XA (2013) and drove a little with that. It was nice.

Until now.

I found out that when I left my bike outside directly in the sun, where the outer temperature is round about 37 Celsius, and then I tried to use my bike, my bike stops accelerating around 4000 rpms. Sometimes also 3000 rpms, which means that sometimes I can only drive around 40 km/h. Also in neutral, when I accelerate fast, then it just stops and doesn‘t accelerate for a little, and then it accelerates a little bit and then stops again and so on.

I found out that when I pump new fuel inside the tank (when the tank is around 1/2 of fuel), then it works perfectly for a few hours. Or if I put the bike around 30 minutes inside the garage, it works also again.

Does anyone have the same problem and maybe a solution?

I will keep y‘all updated, if there are any new news.
