Casey Stoner and Dani Pedrosa had to sit out the second day of testing at Sepang waiting to get the all-clear from HRC after Pedrosa experienced an engine failure on the first day.
Due to an engine failure on Dani Pedrosa's RC213V machine yesterday, HRC sent the engine to Japan for analysis.
The feedback after the investigation was positive, however it arrived after lunch when the Sepang circuit was drenched by heavy rain, so unfortunately the Repsol Honda riders were unable to take to the track.
Casey Stoner and Dani Pedrosa will return back on track tomorrow and resume their testing programme.
