One of the few negatives about driving a sidecar outfit when it is really cold out is the wind that blows between the sidecar & the bike and freezes my right leg. The same wind pushes the warm air from the rad across my left leg, roasting it when it is above freezing. I have been thinking about moving the rad for a few years and last fall I figured out the basics but didn't have time to do it. I also want to put on higher handlebars and raise the fairing a bit so that I can sit a bit more upright. I intend to combine these projects by welding sections of U-channel to the fairing bracket (cowl stay) to raise the fairing and adding supports for the radiator to it at the same time. If I have time I intend to put a deflector with a door in it behind the rad & fan so that the heat will be directed below my foot on warm days but across my legs on cold days.
Adequate cooling in this machine is rarely an issue since it is usually only on the road from October to April (southern Ontario so we don't see -35c too often). The new rad is about the same area but a bit thinner (its also aluminum instead of brass if that makes any difference).
Oh, and its a CX650
, not a CX500... Its sidecar is a Velorex 700 body on a Ural frame.
I haven't had any cooling issues on my 'Wing so far and its sidecar is pretty big & heavy (a modified Dnepr chair - it probably weighs close to 50 Lb. more than stock between the extra steel and the body filler & fibreglass). It does chug back the gas a lot more than it did without the sidecar, though.
