Why not start a petition and present it to them about the pit bikes?
With the cost of the new 4 stroke (big bikes), Vintage seems to be the place to be. I'd like them to have a front disc brake class, or a "Bomber" type of class for 20 year old bikes, so we could more easily find a bike to race with, where every part isn't completely obsolete. They have some more modern bikes that race in the road racing events.
About the pit bikes-- any pre-1985 air cooled two stroke 60, or XR75/80/100. No big bores, just suspension mods allowed. Two classes that run in one race-- 16-39, and 39+. How's that sound? I'd love a YZ60, KX60, or an '83-'84 14/17 inch wheeled XR100 with a boxed swingarm. Haha! Let's make it happen!
