Casey Stoner was disappointed to miss out on pole position for the United States Grand Prix to Jorge Lorenzo.
The Ducati rider looked set to head the grid for the Laguna Seca race before being knocked off pole by the Yamaha rider with just nine seconds of the session remaining. He believes that vital minutes were wasted during qualifying due to changes to his GP10 machine not being made quickly enough.
"I'm disappointed because we didn't utilise the time we had [in the session]," said the Australian. "We had the same set-up as this morning and tried some things that just didn't work. There was one thing in particular that took a long time to change, so we wasted a lot of time there."
The 2007 World Champion, who has now qualified second for three races in a row, still thinks he can fight for victory, but believes that his bike needs numerous adjustments to help his cause.
"For sure we need to improve it. Even during that session we did improve and I'm happy with the way we progressed, but I could have gone even quicker," he added. "I'm still happy to be on the front row though and hopefully tomorrow we can push more towards the front that I've been doing this year. We're more towards the front than last week [in Germany] anyway."
