Buzz,
This works real good for me. I have a notebook. After every change to the engine, intake system, or exhaust, I run it on a dyno to set the fuel mixture. I get traces of the mixture, torque, and horsepower. This goes into the notebook. This can be done before or after the race, but it works best if done before. Then, I note all of the gear and chain reduction ratios in the engine and drive line, including tire circumference. Also, spark plugs, jetting, spark advance angle, and cold compression. At the track, I note surface condition, the fuel I am using, and the tire pressures. The timing slips give me temperature, humidity, etc.
Then I run. The all important info is the tachometer reading. I use the same tach on all runs and every year. Tachs are not all the same and this gives me a good comparison on a year-to-year basis. I write down my impressions about engine performance, handling, etc.
After the run I use the tachometer data, gearing data, and tire circumference to calculate my speed assuming no tire slip. Then I look at my timing slip to get my actual speed. Some basic division gives me a tire slip factor. Throughout the next year I use the data in the notebook for all sorts of other things.
I am sure you do this after your long racing career, but some of this may be new. A lot of people collect far more data than I do. Good luck on your maiden run. The bike look like it is almost ready to go.
