Leon Haslam said it has been another difficult weekend after two ninth-place finishes in the seventh round of the World Superbike Championship.
The Derbyshire rider struggled in Aragon, Spain and finished well behind Italian race winners Marco Melandri and Max Biaggi.
The BMW rider told his website: "It has been another tough weekend for us.
"We just have to go through the data now and get ready for the next round. We've still got a lot of work to do."
Haslam added: "In race one I didn't get a good start and left myself with a lot of work to do.
"I felt like I had the pace to run with the second group of riders who were fighting for fourth place, but I made a mistake on lap one and was not able to bridge the gap.
"In race two I got a better start, the one I was hoping for in the first race. Sadly I did not have a good feeling with the machine, as we went for a softer tyre and I did not have the same level of grip."
Haslam, who placed fifth in race two of the sixth round at Misano in Italy after crashing out in the first race, lies in sixth spot in the standings on 120 points.
He is 141 points behind series leader Carlos Checa (261) ahead of the next round in in Brno, Czech Republic over the second weekend in July (8-10).
