In Southern Europe teams have been troubled by the poor weather conditions in pre-season with Kawasaki and Honda's efforts at Aragon weighed down by freezing temperatures and rain in Portugal, which has not helped.
Ducati with Aprilia, EBR, MV Agusta and Suzuki are also unable to work on their bikes, Giugliano was particularly frustrated at being unable to focus on anything more than electronics and suspension.
"Unfortunately this two day test was compromised by the poor weather. We only started to work in dry conditions in the early afternoon of the second day. It's given us just a first taste of the newly-built 2015 bikes really," he said.
"We've concentrated on identifying a base set-up for both the electronics and the suspension, with used tyres, without worrying too much about lap times.
"We have another two-day test at Jerez next week in which to continue preparations before leaving for Phillip Island. We hope for some good weather there so that we can work hard throughout the two days," he added.
