Airwaves Yamaha's Leon Camier has assumed control at the top of the British Superbike second practice timesheet as the only man to dip under the 1'26s bracket, setting a 1'25.781 with his final lap.
The Kent youngster went half-a-second faster than team-mate James Ellison, who led the field this morning, with Hydrex Honda's Stuart Easton third and Simon Andrews, on the MSS Kawasaki, in fourth 1.2s in arrears.
Ellison opened his account with ten minutes gone, setting a 1'27.219 with Camier in close attendance before the Worx Suzuki of Sylvain Guintoli popped into second place with a 1'27.439. But the Hydrex Honda of Tommy Hill and Buildbase Kawasaki's John Laverty not far behind.
Motorpoint Yamaha's Graeme Gowland crashed at Abbey for the second session in a row with half an hour left in the session but he walked away from the incident, as Andrews parked himself at the top of the sheets, posting a 1'26.986 which proved to be his quickest lap of the session.
It was then a straight scrap between Camier, Easton and Ellison for the top spot. Two laps after Andrews set his time, Camier went quicker by two-tenths as Relentless Suzuki's Ian Lowry made a brief foray into the top three.
Ellison claimed second with 25 minutes to go as HM Plant Honda's Josh Brookes crashed and re-joined at Luffield. Easton then went second with a 1'26.595 but Camier upped the pace further with a 1'26.101.
With five minutes left, Ellison cemented second with a 1'26.291 and on the final lap, Camier set the fastest lap of the day. Hill came up to fifth with his last circuit, dragging the SMT Honda of Karl Harris in sixth.
Lowry ended the session in seventh 1.4s off the pace with Brookes eight, Laverty ninth and the sister Motorpoint Yamaha of Chris Walker in tenth on a 1'27.305, slightly quicker than his time this morning.
