Lexelle-sponsored Tarran Mackenzie battled to a sixth place finish without a fifth gear at Oulton Park to move up to seventh in the overall championship.
In the Superstock 600 class, the Team WD40 rider qualified in fifth place on the grid and raced into third place on the third lap.
However engine trouble scuppered his chances of back-to-back podiums and in the end was lucky to finish the race at all.
“My bike started jumping out of fifth gear,” Tarran said.
“I was frustrated but also nervous as it made things quite dangerous as I was alongside other riders for most of the race.
“I eventually dropped back to sixth but was really lucky to finish as I had no fifth gear at all on the last few laps.
“I was disappointed but then happy when I found out I had moved up to seventh overall in the championship.
“I’ll have a new engine for Cadwell Park in two weeks so can’t wait to get racing again.”
His brother, and fellow Lexelle-sponsored rider, Taylor was frustrated by the safety car in Sunday’s feature race after an eight place finish in Saturday’s sprint.
The Tyco Suzuki rider is happy with his set up on the GSX R600 but just waiting for a change in fortune.
“I’ve changed a lot set up wise on my bike since I last rode at Oulton Park and it has paid off as my lap times were much more on the pace this time,” Taylor said.
“In the wet feature race on Sunday I got to fifth by the second lap and was confident of at least holding my position or even moving forward.
“Unfortunately the safety car then came out after a serious incident for a good few laps so the track started to dry out, which meant we resumed the race on a dry track with wet tyres fitted.
“At this point I struggled more than the other riders so could only manage to hold on to tenth place at the finish.
“My bike, starts and pace all seem to be good now so as long as bad luck stays away I’ll be pushing hard again at Cadwell Park in two week’s time.”
