Just got back from Keith Code's California Superbike School at Texas World Speedway near College Station, Texas. Spent two days taking level 1 and 2 on their '03 ZX-6Rs. During lunch break I would pick the chief mechanics brain on the school bikes. A few of the things I learned was that the bikes never break. They have about 30 bikes and they have lunched one transmission and that is it. They run 31 front, 29 rear on 208 Dunlops. They use Silkolene 15w50 oil because that is what they get for free. Every thing on the bikes is factory except plastic. They pull the stock stuff off and store it and use just the Shark Skinz upper with no belly pan.
