The Italian's best time was just over a second off the fastest lap of the day, set by countryman
Valentino Rossi, but Capirossi is confident that there is more to come from his Rizla Suzuki.
Capirossi's GSV-R was the tenth fastest bike through the speed trap this afternoon, 11km/h behind
Sylvain Guintoli's Alice Ducati, which reached 329.3km/h along the 1.2km straight.
"It's been quite a positive day for us because we have tried many things and we have found a good setting for the bike," said Loris. "We went a bit softer on the front set-up this afternoon and although it is still not perfect we know what needs changing on the bike tomorrow.
"We are not yet 100% certain on the tyre for the race, but we have a good idea and we will run it for a lot of laps tomorrow to make sure it will be right for the race. I am close to the top-guy and I made a couple of mistakes on my last two laps or I would have gone even quicker. I think this could be a great weekend for us!" he insisted.
Team-mate
Chris Vermeulen set the twelfth fastest time, but stuck to just one tyre this afternoon.
"We tried a lot of things with the bike set-up today and definitely made some big steps forward this afternoon," said the Australian. "I used the same tyre for the whole afternoon session, which was probably not the best option as I struggled to get as much grip as I wanted when we were making so many changes to the bike.
"The good news is that Loris used a tyre today that I didn't and it seemed to be a big step forward for him, and as I have it in my allocation I will run that tomorrow and I'm really looking forward to seeing the difference it makes. We are confident for this weekend and are looking forward to what should be a good race," he added.
