not to push you why not the racing:infrandom. they have a beginner class where most of the people are first timer and also new to the sport and racing in general. it's alot cheaper then roadbike td and tire wear etc... anyway hope to see you out there
in order of preference according to cost:
1. sm track day $80 (up to 7.5 hours of track time)
2. roadbike track day $150-$190 (7 - 20 minute sessions)
3. sm race $155 (3 races -- how much time is that on the track?)
4. roadbike race (3 races -- $20 gate fee, $190 for 2 practice sessions and 3 races 8 laps each)
actually thats probably also preference according to the fun and track time chart.
now that i've reviewed the class options
http://www.esmra.com/pub/2008/CompetitionCategories08_062208.pdf i have no idea what i can run. i changed my carb to the fcr39 carb, new pipe and the recommended 3x3 airbox mod. doesnt look i can participate in any races except for 'beginner'. there's no way im doing all of that travel to run in one race unless someone can explain it better than how im reading it.
