I am looking to race some MX or some Cross Country for the first time, but don't know where any tracks are in Oregon. If anybody knows of anywhere, your help would be much appreciated. Also, I am 14 and ride a 400ex. Can I race something over 90cc if I'm under 16, or does it depend on the track? What are the best "bang for your buck" mods. I am saving up my money for the Curtis Sparks X-6 Complete Exhaust, Ignition Advance Key, Rev Box, K&N Power Kit, AC Propegs, Pro Design Kill Switch, any other cheap suggestions? Do I havfe to have headlight protectors? Thanks...
