Problems with hot starting the engine... Please help!!!

Good day! I barely speak English... Problems started with my mt-10 in the heat. It starts on cold without any problems, on hot if you stop for 10-15 minutes it starts badly, turns the starter for nothing three times, then catches on and works fine.. If you turn it off and start it right away (well, or after a couple of minutes), it starts without problems... A motorcycle with a mileage of 4,500 km.. What can it be and what would you recommend to see.. We don't have dealers in our country, so we'll have to figure it out for ourselves...
