On the Berlin trip some years ago my Ruby had the side deflectors in place, and I occasionally suffered fuel vaporisation. It seemed to me that those who did not have side deflectors did not have the problem. I conclude that the air reaching the carburettor is cooler if some of it has bypassed the radiator. In my many years of Ruby ownership it only became a problem as petrol was modified to a more volatile mixture.
