I have a B10 cam so its not highly tuned, it does run 40mm carbs and a lightened flywheel, most of the mods are to the chassis. I have 40mm california forks with modified internals, 17 inch wheels with modern rubber and three frame braces, that really eliminated the weave in the fast corners! I do have a taller ratio but not a shorter one, its certainly too tall for talladega! I think everything but a dirt bike would be! I have considered a lower final ratio, maybe I'll look into that. My camera is an old hero 3, seems to work pretty well although you can see waves on a bigger screen, vibration I'm sure.
In this race its mostly against honda 900s, suzuki GS1000s, kawasaki z1s, even cbx! They are allowed 1000ccs and I am allowed unlimited, although it is still an 850, I dont run two bikes.
