MotoGP World Championship leader Jorge Lorenzo has had a painful time at Laguna Seca during his two previous visits, but the 2010 event got off to a far more serene start as the Fiat Yamaha rider finished a close second to Casey Stoner.
Having lapped 0.233sec behind Stoner by the end of Friday practice, when he was over half a second clear of nearest title rival Dani Pedrosa (fourth), Lorenzo revealed he plans to make some adjustments to his riding style tomorrow to better suit the unique nature of the Californian track.
"This was a good first practice and everything came quite easily; we didn't find any big problems and I was able to be at the front from the start. That said it looks like Casey is very strong here and we will have to work hard to catch him!" said the Spaniard.
"I think I need to make some small changes to my riding style tomorrow rather than big changes to the bike setting and hopefully this will help us to find a few tenths and make sure we can fight on Sunday. A lot can change and I hope we can improve some more tomorrow."
"We need a bit more time because we need to improve the balance between the front and rear, but we know that it's very difficult to have everything perfect at this track because the corkscrew is very unusual!" added team manager Wilco Zeelenberg.
Team-mate Valentino Rossi was sixth.
