Stoner says Honda still has work to do despite topping the timesheets in Sepang

The Australian said he was generally happy with the bike's balance and traction, but said the task of reducing the chattering and experimenting with the electronics left the squad with work to do.

"Again we've been unable to profit from the full three days of the test here in Sepang," Stoner said.

"Today [it was]"good to have some nice weather, get out on track and find some different solutions on the bike, we've been trying a few different things with electronics to have the engine character the same way we like it.

"We've also tried shortening the wheelbase, aiming to reduce the chattering and we've been successful in decreasing it slightly but at the moment we're unable to eliminate it completely, so we still have quite a lot of work to do."

Stoner added: "In general we are happy with the bike. The chassis balance feels good as does the traction on the bike, it's turning well but we really need to get rid of the chatter."

Pedrosa said Honda also needed to improve its entry to corners, but predicted Honda would be able to make progress in the third and final test in Jerez.

"We need to keep improving on entry and middle of the corner, but I think that we can expect improvements when we start to work more in depth with the engine and the electronics, which we will do in the Jerez test," he explained.

"In general we've been working a lot on the chassis at this test, to find the best compromise. We tried different ideas and set ups and we leave quite happy with the feelings."
