Pata Honda World Superbike duo Jonathan Rea and Leon Haslam are continuing to struggle to make a breakthrough with their new HRC electronics kit.
The pair have wrapped up a three-day test at Motorland Aragon in Spain ahead of next week's second round of the World Superbike Championship at the same venue.
A frustrated Haslam said he had been unable to make any progress with the system from Phillip Island.
“It's been a frustrating few days actually because we haven't been able to move the new electronics on from where we were in Australia in the first round,” said Haslam.
“The weather today didn't help either and there's a lot more work to do before we're ready to challenge properly next weekend when we come back to Aragon for round two.
“Physically, I'm feeling good after the recent operation on the foot I broke last year, so I'm ready to do some more testing before then.”
His team-mate, Jonathan Rea, agreed, with the Northern Irishman admitting the teething problems with the advanced HRC electronics still remain.
“I did a back-to-back comparison with last year's electronics and it's easy to see the potential that the new system has.
“However, the teething problems we had in Australia don't seem to have gone away so we haven't got as much out of this test as we wanted,” Rea said.
“We've got another couple of days testing at Alcarras next week, which will be really useful. We've also got some good brains working on the system, so we know there's more to come.”
Haslam and Rea will continue testing at Alcarras in Spain on Sunday and Monday before returning to Aragon.
