JCZ and Twolane;
Usually once it warms up where its 75 or better most days I take the air baffle off. It helps a little bit with drafts and turbulence, but not as much on this bike as on my RoadKing. I do however notice that when it is hot outside that my boys tend to roast unless I take that baffle off. I think that taking the baffle off moves the hot air from under the tank so I don't fry. I've not heard of this baffle causing the front cylinder to run hot.
The little plexiglass wings are what really make a difference. I try to leave them on most of the time just because they cut the turbulence down so much. If I really start to get hot I keep a couple of zip-lock bags and just put the little wings in the saddlebag. It's really amazing how much these little things block the wind. All out of proportion to their size. [smiley=beerchug.gif]
