There was an NCR a couple years back at Daytona. He cleaned up in the classes he ran. As Marc has said the LW legal Bimotas have the air-cooled 2-valve motors and I am sure they are around 100rwhp. The leaned on Bimotas have some 120rwhp and now Kevin's is reported to have more now. He did turn some 15's at Roebling this past summer.
