"The tests have gone well and I'm happy. I'm happy because we worked hard and we finished with positive results and a good set-up for when we come back for the race," said the Japanese, who just a fraction slower than his team-mates in seventh. "My long run went very well [mid 1min 35s] and I didn't feel any real pain from my left collarbone.
"The only time I noticed it was when I was wearing my new set of leathers and they put a lot of pressure on it. But I am a racer and my job is to be here and test, not sit at home," he declared. "I changed to an older set of leathers for the run and that was much better. I did not use any qualifying tyres, but concentrated on getting a good set-up for the race and also finding good grip from the rear.
"We also did a lot of work with the electronics and engine braking and these are the kind of things that you must test away from a race weekend because you never have enough time during practice and qualifying," Yuki revealed.
The Valencia race weekend will take place from April 4-6.
