Be Wiser Ducati's Shane Byrne finished the three-day Monteblanco BSB test a little way down the order but said it is better to discover problems in testing and fix them rather than find them over a race weekend.
The reigning champion was seven-tenths behind title rival Leon Haslam on the unofficial timesheets but wasn't unduly concerned after setting personal bests at Cartagena last weekend.
"This test has been interesting but pretty difficult. I've enjoyed the track layout, enjoyed riding in the wet, I like the track but we have struggled a little bit to find a feeling with the bike. I've struggled a bit in braking but my corner speed if really good but my exit speed isn't good," said Byrne, speaking at the track.
"Sometimes it is important in pre-season testing to have some problems because you can concentrate on fixing them. It is better to find them now than at Donington Park or one of the first rounds. We haven't got as many laps in as we'd have liked because of the weather. We have a couple of days at Guadix, so we can experiment there."
