Leon Camier maintained his status as hot favourite to win at Thruxton as he continued to lead the way during morning warm-up.
With a four tenth margin for error, Camier was well up on second place rider Stuart Easton, who shrugged off an indifferent qualifying to claim the second best time.
His late effort was enough to separate the Airwaves Yamahas, James Ellison in third position, ahead of Ian Lowry on the Relentless Suzuki.
John Laverty and Atsushi Watanabe were surprise faces inside the top ten too in fifth and sixth positions, ahead of Josh Brookes and front row starters Michael Rutter and Gary Mason.
