Casey Stoner says he remains fully committed to solving Ducati's current problems even though he will leave the team at the end of 2010, and is not paying any attention to future employer Honda's strong form.
Ducati has yet to win a race this year, while Stoner's future Honda team-mate Dani Pedrosa scored his third victory of the season at Indianapolis last weekend and dominated ahead of his team-mate Andrea Dovizioso in Friday practice at Misano today.
But Stoner, who was only eighth fastest in today's session, said his 2011 team's performance was of no consolation whatsoever amid Ducati's issues.
"I have to worry about us at the moment," said Stoner. "I don't give a crap about what anybody else is doing at the moment.
"At the moment, we're struggling with our bike and we need to concentrate. I honestly don't care if the Yamahas are going well, if the Kawasakis were here and they were doing well. At the moment, we're not.
"At the moment, we are the slowest bike out there. There are four manufacturers and many times we are the most difficult one.
"So we have to pick up our game, and I know we can do a much better job than what we're doing."
The former world champion said he still did not feel the team had found how to extract the potential from the Ducati GP10.
"It's just difficult to find the solution that makes this bike work," said Stoner. "We've been able to get a great setting for a lot of races, but not a fantastic one, so we just need to keep working."
Stoner has been persisting with a new fork specification at Misano this weekend, and reckons the best policy is to continue making bold changes to the bike.
"At the moment I've got not a lot to gain and not a lot to lose," said the Australian, who is fourth in the championship, 132 points behind leader Jorge Lorenzo, at present.
"We're just going to keep trying different things and see if we can come up with a solution, because I'm sick of finishing third, being on the podium but on the last step and too far away from the lead, so we have to try something big.
"Unfortunately when you try something big, it doesn't necessarily mean you'll arrive at the best setting first time. We have to keep trying a lot of crap settings before we come across a good one."
