Hi, just joined and I have the same question regarding the 'Motorcyle Innovations Bad Boy Oil Cooler'. I've ran AMSOIL since the bike was new, maybe over-kill but I drained it at 500 and 1500 each time replaced with the proper AMSOIL product. I have about 24,000 miles on 'Delila' (oil changed every 5000-6000) and I just started noticing a little more heat coming up from the motor at lights, hence my thoughts of: "maybe it's time to consider an Oil Cooler of some sort". so, any help would be greatly appreciated. I like the Bad Boys' design verses HD/Jagg's product (JP catalog)
