Yes you can ride without the baffle, all the blower bikes do. The heat is not significantly greater. The difference in the I/S is the baffle has wings that extend out into the pods. I ran this bike without a baffle for a couple of years with a blower, back to carbs now, and am running the std/tour baffle even though I have the pods. Was thinking of leaving it out, but it was there and I installed it.
