The baby faced Michael Laverty is hoping to pull off a dramatic victory and become the first Ulsterman to win the British Superbike Championship.
The final hurdle is at Oulton Park Cheshire, where Laverty will be racing in three legs.
At present Laverty is 19 points behind the leader Tommy Hill in fourth place and obviously three wins of the final round would boost his chances.
“Everything depends on the placing of the other leading contenders,” said Laverty.
“If I hadn't crashed in the previous round at Silverstone I would have virtually lifted the title. As it is it's going to be a nerve wracking experience over Saturday and Sunday.”
The last Ulsterman to go close in the British title was Jonathan Rea in 2006. This was the year when Rea also won the Sunflower Trophy at Bishipscourt.
By coincidence Laverty could also go to Bishipscourt with a big win behind him. On this occasion Laverty is a hot favourite for the Sunflower, which he is bidding to win for the sixth time.
His most recent success was in 2007 and he is itching to score another Sunflower victory.
He said: “I'm going to have a tough time winning with team-mate Alister Seeley in the running.
“Alister is keen to win this race and I know he is not happy to be relagated to second place.
“We are both in the TAS Suzuki Team run by Hector Neill, but there will be no team orders.
“It's a case of the best man winning.”
