Byrne, who is seeking a third BSB title, endured another winless round last time out at Cadwell Park over the August Bank Holiday weekend finishing third twice and fourth and now has just one victory in 11 races.
But the 34-year-old explained his team were sacrificing the final round of the regular season to experiment on making his HM Plant Honda machinery unstoppable for opening stage of the Showdown.
The first of three Showdown rounds, which pit the top six riders against each other to decide the 2011 champion, commences this weekend with Swan Yamaha’s Tommy Hill now leading ahead of Byrne.
Courtesy of collecting fewer podium credits, Byrne trails by seven points and although he lost ground on Hill at Cadwell, he insists the sacrifice will pay dividends when they take to the track at Donington.
“We spent Cadwell Park testing and seeing how we could make the bike better,” said Byrne. “It didn’t help that some of the new parts didn’t turn up in time but we learned a lot.
“We had a difficult time but we knew Donington was the target for getting the bike at its best. We go in seven points behind but that’s not much.
“There are 175 points available overall and if I get two wins at Donington, even if Tommy gets two seconds, I’ll be back at the top.
“But we’re not taking it for granted. There are six riders with a near fresh start, all in with a chance, and I certainly can’t count my team-mate Ryuichi Kiyonari out.”
Twice a BSB champion in 2003 and 2008, Byrne flew the nest for the World Superbike paddock three years ago, and is desperate to taste glory on his return to the British equivalent.
And, although a third BSB title – equalling the feat of Ryuichi Kiyonari – could turn heads on the world stage once again, Byrne insists it would take an irresistible offer to tear him away from HM Plant Honda.
“Winning the championship is what I came back for,” added Byrne. “I have got a great team behind me, they finished first and second last year, and I couldn’t ask more of them.
“I just want to get this season out of the way with first before I start thinking about next year. I wouldn’t want to leave HM Plant for a second-rate World Superbike team.
“If I was going to go, it would have to be the right team. We’ll wait and see what happens, I just want to try and do the best I can this season first.”
