Factory Yamaha MotoGP riders Jorge Lorenzo and Ben Spies were both happy with their wet set-up during a stormy second day at the Jerez test.

Lorenzo was second fastest in the wet behind Honda's Dani Pedrosa, but was shuffled back to 13th after electing not to try for a dry lap in the improving end of day conditions.

"Today we started late because of the weather so we only managed to do 25 or 30 laps in wet conditions," said Lorenzo. "Now we know that the bike is working quite well and is competitive, we were in second place in the wet behind Dani and the next rider, Cal, was a second behind.

"We still need to work on our electronics as we haven't got the perfect solution for Qatar. For tomorrow we haven't got anything new but we need to decide whether to put away some parts."

Spies almost spent most of his limited track time checking his wet set-up, but did try slicks at the end of the session - and moved up to third as a result.

"It's been a tough day but it's been like that for everybody. Luckily we got a lot of stuff done yesterday, a simulation and most of the test settings. Today we just tested some wet set up stuff," said the Texan.

"I was quite happy with that, we didn't get on the track when it was in prime condition for wet but good enough. As the track dried out we needed to wait a little to try one thing in the dry.

"We know what we need to do for tomorrow so we're hoping for good weather."

Pre-season testing concludes on Sunday evening.
