Pedrosa, who was riding for the first time after undergoing arm surgery, finished 13th in FP1 and seventh in FP2.
While the Spaniard was impressed with the pace of the bike, he conceded that he had trouble controlling the speed at times.
"It was different than expected because I had a lot of feelings on the bike, especially in this track because the bike wheelies quite fast!," Pedrosa told reporters.
"I didn't remember how fast this bike was and I had a lot of problems controlling the wheelie and trying to stay full throttle and to control the spinning of the bike.
"The speed at the beginning of practice was tough, many riders were passing me.
"It was hard to adjust my brain to all the little things that you do on the bike but already in the afternoon I was going better and tomorrow I'll have a better feeling for that."
Pedrosa also revealed that his arm had swelled up after his free practice sessions, but added that he will do some therapy ahead of the race tomorrow.
"I had a little bit of swelling after riding so I'll do some therapy to get the swelling down and tomorrow it'll be important to see the level of swelling and the pain," he said. "I did a lot of short runs trying not to stress it too much."
