I had a clutch problem at the start. I tried to do a practice start on the warm up and I noticed that it was slipping. Then on the grid I had to pull it in without being able to find neutral. I had to warm the engine with the clutch pulled in. The bike also started to go forwards so I had to brake at the same time. I did the start as best I could with these problems but it was a bad one and the other riders on my row overtook me. What is more, on the first curve three riders fell just in front of me and they almost took me down with them. I fell back quite a few positions. On the first five laps the bike was bouncing around a lot but it improved later on and then it began to slide. This was a very tiring race, very long and tough. I tried to go flat out but it was not possible. In spite of everything I want to thank the team because the truth is that they have helped me a lot.
