Casey Stoner believes Honda made some progress with eradicating its season-long chatter issues in testing last week, but is not getting his hopes up until he tries the bike in practice at Silverstone.
The reigning MotoGP champion has been unhappy with the chatter generated by Honda's 2012 bike since the start of the year.
He said Honda tried new solutions in the post-Catalunya Grand Prix test, and hopes to see the results in this weekend's British GP.
"The Monday test in Catalunya was a positive step for us, but we're still far from perfect," he said.
"We definitely made some progress with reducing the chatter but we will have to wait until we get on track on Friday to see if what we found also works at Silverstone."
After five rounds of the 2012 season, Stoner trails Yamaha's Jorge Lorenzo by 20 points in the title race.
Stoner's team-mate Dani Pedrosa imeanwhile s optimistic that the gains he made in the Catalunya test will translate to Silverstone.
"As I said after the test we did in Catalunya, we were working a lot on different settings on the bike, we had some improvements and I hope we can make another step forward in Silverstone," said the Spaniard.
