Valentino Rossi couldn't hide his disappointment at finishing the second Sepang MotoGP test in eleventh place, almost two-seconds from the top.
After feeling 'quite confident' following Tuesday's opening day, when he was ninth (on hard tyres) and one-second from the front, Rossi was then forced to miss the entire second day due to fever.
The seven time MotoGP world champion returned today eager to try and make up for lost time - and rode for 59 laps in the exhausting Malaysian heat. But there was to be little reward.
Rossi struggled with cornering and lost a further 0.8sec relative to fastest man Casey Stoner. There are now just two more days of testing, at Qatar, before his first race as a Ducati rider.
“The first day was not so bad, because I was already on the lap time of the first test [earlier this month] and we were one-second from the top,” said Rossi.
“We were quite confident for day two because we had a lot of things to try, like a different setting for the rear, some swingarm link, different suspension.
“I was quite optimistic to improve our lap time, then unfortunately yesterday I could not ride so we lost one day and that made things more difficult.
“Anyway today I felt okay. I made nearly 60 laps and worked a lot on the bike, but unfortunately we didn't fix our problem.
“We are not fast enough in the corners. We have a problem for turning the bike, so I always have to slow down too much to make the good line. I cannot ride the Desmosedici in the right way.
“The position is bad, because we are just eleventh, but especially the distance from first. We are quite worried. We have to try to work to improve our performance.
