I know......... The rules keep changing year on year !! St George is going to be the only place to bloody run a modded bike of any kind soon..including mine .. It does seem as though the governing bodies are following the world champ bodies in reducing mods and therefore costs in national championships. This is good in one way as wildcard riders will stand a chance when the worlds come around , but it hurts people with modded bikes, and as far as big Tony, not many like to run 600s in Formula Factory Yamaha 1000 err I mean formula Oz !! I would think soon that the only mod you will be able to make is carts and shocks :(
