Junk With Wheels
Looks like a Drag Specialties oil cooler from some bizarre angle mate . . . ran one on two of my Bonnies, did a great job.
Not sure who made the oil cooler, but I know it's been on there a very long time. Every where you look on this barge something has been stuck in somewhere. This bike is soooo heavy, it's all I can do to move it around by myself.
