As I said at the beginning of this discussion stripping engines at the end of a race to confirm that the engine conforms to the regulations is a contentious one. How many championships, from club, national, international and world championships have been won by people using engines, and or component parts that did not conform to the technical regulations, I am not saying that all the riders knew who rode illegal machines that they were illegal. In a lot of cases if you were a factory rider you raced what you were given. And in many cases you could not tell from the outside appearance of a engine that it had illegal parts inside. But as we all know it did go on. In many cases the pressure on the scrutineers and technical staff by a winning team or factory NOT to have a engine striped was immense, as per my posting earlier about the 1983 F1 TT. I have been searching for the article that I mentioned in a earlier posting that was written by Norrie White in the 80's ( when I find it I will post it), in that article he eludes to the fact that technically if a entry form has been signed by a competitor, entrant or sponsor they were agreeing that the machine that was to be raced conformed in every way to the technical regulations for that event. Norrie went on to say that if a engine was illegal surely somebody knew this and walking away with any reward was technically fraud. I cant remember if Norrie had received any form of legal advice, or if it was just his thinking. Even in the late 70's and into the 80's racing was very expensive and people needed to have results to carry on racing, but the thought of winning on an illegal bike, and walking away with the money is surely "perverse" ( is this the correct word ? ) weather you are a clubman, and entrant/sponsor or even a factory, and I for one have no doubt that world championships have been won using machines that did not conform to the technical regulations. My father told me once that a competitor was caught in a random engine check at a GP, his engine was illegal and he was banned for a whole season for cheating !, this was in the 40's, I can hear people saying Yes but that was the 40's, what difference s there ???? could you imagine that happening to day !!!!
