The Italian said he was riding at "90 per cent" because he could not find a setting with which he was comfortable.

Crash for Lecuona at turn five. That's four at that corner in this session. His bike is back in the pits as well but seems like less damage than Bautista.
Five minutes remaining in the session.

Five minutes remaining in the session.
Bautista's bike is back in the Barni box and the work going on is fairly frantic with 10 minutes to go in the session.
Third crasher at turn five and it's Alvaro Bautista. Looks like the same crash, more or less, as Bridewell. Again, he's back on and riding back.
Bulega improves again: 1m40.188s now for him. Continuous lapping in those 1m40s, formidable pace from the championship leader.
Crash for Bridewell at turn five. A bit earlier in the corner than Sofuoglu earlier on. He's back up and on his way back to the pits.
Bulega improves his time at the top to a 1m40.255s so he now leads by 0.096s over Montella.
Bulega hasn't pitted yet and he set that lap on his 8th timed lap of this session.
Ducati 1-2-3 now as Montella goes second and splits the factory bikes.
Lecuona goes second on a 1m40.479s, 0.136s behind his teammate at the top of the times.
Manzi runs off into the gravel at turn one as he gets squeezed out by Petrucci in braking.
Crash for Rea at turns 10-11. He seems okay but he's going to lose some time in this session for that.
Lecuona now to the top and 0.010s ahead of Bassani. Top-five, back to Oliveira, now covered by 0.131s.
Bassani with the early benchmark on the Bimota, just under 0.05s in front of his teammate, Alex Lowes.
Bulega third, then Oliveira.
Bright start for Mackenzie in 7th and straight into the 1m40s.
Sofuoglu has gone down on his second flying lap. Looks like he's just lost the front in the middle of turn five.
He's back up and on his way back to the pits.
Pit lane is open in Portimao and we are underway for FP2.
Tommy Bridewell had s solid start to life as a WorldSBK rider this morning, finishing 13th in FP1.
It wasn't without it's dramas, though, as this moment over the crest between turns eight and nine shows.
Somkiat Chantra was declared fit ahead of the weekend yesterday.
He missed the opening round of the season in Australia due to arm fractures he picked up in Sepang in January, and so this morning's FP1 session was his first competitive outing of the year - his first in WorldSBK.
A condition of his passing of yesterday's medical test was that he would be reviewed again after FP1, and he was declared fit once again.
Chantra finished FP1 down in 19th, two places behind his teammate for this weekend, Jonathan Rea, who is standing in for the injured Jake Dixon.
FP1 was a relatively uneventful session this morning. Conditions were more or less perfect with 19C of air temperature and 30C of track temperature.
Only one crash in the session, for Stefano Manzi at turn 13, with little consequence as he rode straight back to the pits.
There were technical problems for a couple of Ducati riders, Sam Lowes and Iker Lecuona. Lowes topped the session and Lecuona was fourth, so no huge dramas for either of them despite losing around 10 or 15 minutes of running each.
Nicolo Bulega had a reasonable start to the weekend, too, finishing second this morning, and Alex Lowes completed the top-three after being the first riders to lap in the 1m40s. His teammate, Axel Bassani was solid, too, in sixth.
