We changed the clutch. I made a normal start on the grid for the warm-up lap, but the bike stopped. I'm happy that in the first race I was able to start well. I was fighting at the front, but in the second race the feeling was not the same. We changed the tyres, and I don't know why but the bike was spinning so much, even on the main straight. I tried to go up the order, but then I had problems with the bike, and I stopped.
