I carn't help feeling that this is all because one of his tuned engines was found to be illegal. Lets be honest about this, if you tune your engines to the full then they will not last long... that is not rocket science. If you are told by a tuner that the motor needs an over hall at a certain distance its down to the riders to comply with the tuners instructions not the technical committee. These are highly tuned motors and can go wrong, if the race is 4 or 6 laps the riders need to know from the tuners when to check the engines. We had three when we did the TT sidecar races, one highly tuned - went bang after two laps - one not so highly tuned - went a bit iffy and the last bog standard with only a few mods. They can all go at any time ... this seems like sour grapes to me.
