been wondering about this..
would adding one or two 12v cooling fans (3 inch dia. computer or amp cooling fans) bring enough heat in the cab to make it worth while to try this?
ever since I got my 900s I have been thinking about trying this out.
I’m not worried about water intrustion in the cab because I wont be riding in any water during the winter months.
it could be wired directly to the battery with a switch in between them and run the wiring to the battery with a male female plug to disconnect it.

I may just buy an extra door and give it a try to see if it works.
