This may seem strange, but it seems to be a fact with mine. I have the Baker wings w/lowers, just like I had on my 03. But with the 04, there's almost no heat coming from the radiators. I used to open up the lower wings, and draw heat towards me, now all I get is cold air. I know the 04's have the new ECM, but did they do somthing with the thermostat? The temp. gauge stays just below center when warmed up. We rode for 85 miles today, & that was a cold 50 degrees at 70 MPH.
