What's that whirring sound? According to Ammar Bazzaz, the Yosh Superbikes aren't using gear-driven cams, although they could in the future. The distinctive high-pitched sound we're hearing could be the dry clutch, says Bazzaz.

A feature of Yosh's new data acquisition system allows the crew to send a message to the rider via the dash while the bike is on the track. For engineers or those with overactive imaginations, that presents an endless world of possibilities should systems like that ever be declared legal.

On-the-fly computer changes could allow for different injection maps and ignition settings in different parts of the race. Depending on the situation, the team could give the rider a more ideal bike for pure speed, wet conditions, or tire conservation.

On the system currently in use, optical heat sensors relate tire temps back to the computer screen in the pits. In the future, this could predict, and possibly eliminate, some tire woes. When the numbers reach levels at which the tires begin to degrade, the team's monitoring the data in the pits could send the rider a signal to ease back the pace.

Of course, it is worth reiterating that systems like this are now illegal for competition.

The Honda Superbikes don't look very much different (apart from a taller windscreen on DuHamel's RC5) than they did at Willow Springs, no Woody logos as yet, but other riders report the RC51 is very quick on the banking.

Yamaha's factory machines look to be quite trick, and there are four Japanese gentleman in the red, white, and black regalia of the Yamaha Japan.

It is unknown if Hayden and Gobert's R7s are ex-Haga, ex-AJRR, or Suzuka Eight Hour machines. The bodywork had headlight cut-outs, as seen in endurance racing.

HMC Ducati seems to be doing well adapting to riders with two different testing styles. For Mr. Daytona, the emphasis seems to be getting the setting he wants to cut really fast times. Russell told observers he's looking to hit the 49s today, a time he did on the Muzzy Kawasaki seven years or more ago, but still a very fast time at Daytona.

The Modus Operandi for Slick Bass and crew has been to make an adjustment, have Russell do a handful of laps, then come in.

Steve Rapp, on the other hand, has been circulating the track for long stints. This morning he put 30 laps on one tire, and he's been on the track more than any other rider. Rapp then crashed.
