Nah You shouldnt need to protest mick, why should the guy in last have to protest the guy in 5th and so on just to keep the integrety in the sport, its about people taking simple steps to makes sure theyre doing the right thing, the owness should be on the rider, surely at the least its it an honour thing.
I find it a little hard to think anyone in the sport wouldnt be able to know if there stuff is Kosha, and if there is any doubt on what model your bike is, its prity easy to ask someone.
Still not the organisers fault, they put on a good show.
And firko thats not the one im talking about, its more the DT400's and the 77 250cc barrel/radial in pre 75. That one your talking about was at least riding up into the right years....
