Shane Byrne has held on to top spot on the timesheet in a delayed free practice three after track damage and poor weather suspended any morning action, while the mixed conditions saw a shake-up at the top with Be Wiser Kawasaki's Danny Buchan taking second ahead of JG Speedfit Kawasaki's James Ellison.
After just under four hours of delays due to track and weather problems FP3 finally got going at 1.40pm. The majority of riders initially took it steady not to wreck their bikes ahead of qualifying. The sessions also gave riders an opportunity to test the relayed surface after severe overnight storms broke up the top-side of the track between the start/finish line and turn one.
Bennetts Suzuki's Christian Iddon led the first group out on track as Howie Mainwaring-Smart set the early pace – a 53.223s – on the drying surface.
As the relatively uneventful session quickly ticked over into the final ten minutes all the riders went out on slicks expect for Be Wiser Kawasaki's Chris Walker and Morello Racing's Lee Costello.
The track was effectively dry which enabled times to tumble back towards the pace seen during Friday's blisteringly hot sessions.
Byrne grabbed top spot to take a clean sweep of practice sessions with a 49.278s, edging out Buchan and Ellison. Tyco BMW's Michael Laverty maintained his strong weekend in fourth while Luke Mossey on the Quattro Plant Kawasaki moved up the timesheet to complete the top five.
The mix-up saw Milwuakee Yamaha's Josh Brookes slip to sixth spot ahead of Team WD-40 Kawasaki's Jack Kennedy. Buildbase BMW's Ryuichi Kiyonari was the meat in the Bennetts Suzuki sandwich with Iddon taking eighth, Kiyo ninth and Josh Waters tenth.
