A BRAVE decision didn't quite pay off for Jake Archer as Tom Booth Amos left Oulton Park with one hand on the Championship trophy after another double win in The Hel Performance Motostar Series, writes John Willumsen.

The Motostar field were first out on Saturday morning for qualifying. The track was damp and many riders delayed entering the session but Booth Amos eventually took pole with only eight laps under his belt with a time of 1:49.815, considerably slower than his new lap record but good enough to take P1 ahead of Eugene McManus and Archer in third.

In race one, Booth Amos destroyed the field and smashed another lap record, on route to his 14th win of the season. Archer was second, collecting his 14th podium trophy, ahead of Richard Kerr in third.

With Booth Amos away at the front Archer battled with McManus for the remaining podium positions. McManus made a mistake on lap nine and slid out, allowing Archer to follow his teammate home with Kerr completing the podium. Booth Amos opened up a 33 point gap at the top with Race two to come on Sunday.

Booth Amos was confident going into race two and Archer knew he had to try something to upset his teammate's rhythm.

With the track wet and conditions set to improve, Archer gambled on changing to a slick rear hoping to capitalise once a dry line appeared. Unfortunately for Archer, it didn't happen and Booth Amos stormed to his 15th win of the season.

Just 10 minutes after the race had finished, the sun appeared and Archer bold tyre choice could well have paid dividends.

Second place man Storm Stacey finished a massive 21 seconds behind Booth Amos with Richard Kerr collecting his second podium of the weekend in third.

Archer said: " I had to do something, Tom's been unstoppable this year and I gambled on the slick rear, I still have a chance to beat him to the title but it's going to be tough now with just four races left."

Jake now heads onto Assen for the penultimate round over the weekend on September 29 to October 1.
