Valentino Rossi shared the top spot for Yamaha on the final day of the Sepang II MotoGP test as the Italian star set the joint fastest time of the week on the YZR-M1.

Rossi and Repsol Honda's Dani Pedrosa both recorded times of 1m 59.999s as the test reached a conclusion in Malaysia - the only riders to post a sub two-minute lap.

Bridgestone's new tyres have been causing problems in particular for Rossi's team-mate Jorge Lorenzo, who has complained about the lack of edged grip.

Lorenzo finished seventh on the times on Friday, 0.620s behind the leading pair and afterwards Rossi said the Spaniard's style was making it more difficult to achieve a fast lap time on the new rubber.

"The bike is much more difficult to ride with this tyre because there is no grip on the edge and Jorge spends very much time on the edge of the tyre," he said.

"It is not his real potential and I think Jorge will be competitive at the first race.

"We have to continue to work and we already have some ideas to try to improve. It looks like this is a problem for us and Honda does not have the same problem, because they are very strong.

"Honda is faster than us here in the pace but was already faster than us in the race at the end of 2013," he added.

"We have to go to another track to understand if there is the same gap."

Rossi attempted a race simulation but decided to stop after encountering trouble with the front tyre.

"I started with a simulation and had a very good pace so I expected to do a good run, but I had a problem with the front tyre," he said.

"I don't know if it was a particular problem with the tyre, or if it was the full tank and higher temperature, but the front pushed very much and I was slow and I decided to stop."

The Italian legend, who has vowed to continue for two more years in MotoGP if he remains competitive, has been in impressive form during both Sepang tests in February and has eased into his new working relationship with crew chief Silvano Galbusera, who was brought in as a replacement for Jerry Burgess.

"I feel very good with Silvano. We work very hard and want to always try to find something better. He is very good at working on the computer for the electronics system of the bike," Rossi said.

"I'm happy because there is a good atmosphere also with all my mechanics. For sure they were shocked about Jeremy and sad, but now they feel good also with Silvano."
