Colin Edwards regretted using an untried set-up in Sunday's Czech Republic Grand Prix race, but was able to build on what had otherwise been a positive weekend during Monday's MotoGP test.

The Monster Yamaha Tech 3 rider equalled his best finish of the season with seventh in the race, but wasn't happy wit the change of set-up.

During the test, Edwards spent 41 laps assessing different front-end geometry settings and a revised front tyre specification from Bridgestone. His best lap was good enough for sixth on the timesheets, and was almost a second faster than his quickest in the race.

"We made a change with the set-up for the race yesterday and I didn't really have a good feeling with the bike, so we reverted back to the setting I was happy with on Saturday just to try and understand why I wasn't able to run the same pace," said Edwards.

"I've learned not to race the bike with a setting that we hadn't tested but we thought it would be fine.

"I tested some different front-end geometry to try and make more progress with the better turning performance we found earlier in the weekend and we've got some more ideas for the future.

"I tried a new Bridgestone front and I was really happy with that so it was a good test.

"Although I wasn't happy with the result yesterday, I felt we made a breakthrough with the bike here and I'm really looking forward to challenging for my first top six finish of the season at the next race in Indianapolis," he declared.

Team-mate Ben Spies, who got to try the 2011 Yamaha, was 0.063sec slower than Edwards at the test.
