You're wrong there. When it is hot, opening them brings air into the rider to provide some cooling.All should be ridden closed except in cold weather when opening them may divert some air from the radiator to your legs.
bought the same for the same reason. glad to hear they help.I did the show chrome uppers about 2 weeks ago, as the wife was complaining about buffeting around her head/shoulders. We did long weekend trip and at highway speeds i pulled them open and closed. She said there was a big difference in how much air was directed away from her. I will probably do the the lowers next. I’m very happy that they flow well with the look of the bike- still sporty.
