Ben Spies, still chasing his first podium of 2012 after failing to finish the last three rounds, left this week's private Aragon test feeling optimistic for the end-of-month grand prix at the same circuit.
The Factory Yamaha rider completed 95 laps on Tuesday and a further 76 on Wednesday, the best of which was 0.7s behind pace-setting team-mate Jorge Lorenzo.
Spies, who will leave Yamaha at the end of this season and be replaced by Valentino Rossi, worked on the general base set-up of his M1, as well as race set-up and tyre life specifically for the Aragon Grand Prix.
Like Lorenzo, Spies conclude testing with a race simulation run.
“We basically tested the bike over race distance here and completed a race simulation to set the bike up with a focus on the end of the race,” said Spies.
“We worked on some different fork and shock settings and a little bit of electronics but nothing major.
“We were mainly fine-tuning the bike and the results seem good. I'm positive for the rest of the year. The package we have now was good over the race simulation so I'm optimistic for the race.”
The San Marino Grand Prix at Misano will be held on September 14-16, followed by the Aragon event.
Pramac Ducati is the latest team to be mentioned in connection with Spies for 2013.
