Jonathan Rea has toppled Kawasaki team-mate Tom Sykes for the first time this race weekend at Donington Park which sets up an intriguing race two after the Huddersfield rider produced his seventh straight win at his home event.
The reigning World Superbike champion had been struggling with mechanical gremlins in Saturday's race one but recovered from the problems to maintain his rostrum run with third place behind winner Sykes and Davide Giugliano in second place.
Rea has clearly got on top of the issues, which repeatedly flicked him into false neutral during race one, as he topped the morning warm-up by just over a tenth of a second from Sykes.
It is the first session all round Sykes has been bumped off top spot but still produced strong and consistent laps in warm-up to set up an intriguing battle at the front.
After a difficult race one, Chaz Davies also enjoyed gains to take third in the warm-up session ahead of Aruba.it Racing Ducati team-mate Giugliano.
Nicky Hayden, who grabbed Honda's best result at Donington Park in three years with fifth place in race one, maintained the same position with Leon Camier continuing his fine work on the MV Agusta in sixth.
Front-row qualifier Lorenzo Savadori grabbed seventh ahead of Michael van der Mark, as Josh Brookes broke into the top ten for the first time this weekend on the Milwaukee BMW as Alex de Angelis completed the top ten.
