My solution to has been to buy the Jagg 10 row and invert it up on the crash bar to get a clean un-obstructed air flow to the cooler between the forks (i used 1" conduit clams) I have also left the stock cooler in place and run them in series witch help out with the oil temps in summer, In cooler months I made a thin aluminum cover that fits between the stock cooler and stock cover. I have also added a neoprene front fender mud flap that extends down about 2" from the skirt
How about some pictures.
