This setup works great. My oil tank stays cool enough to not make my leg uncomfortable. All the machining looks good. The oil cooler looks good and fits my sportster like a glove. Mounting it is easy.It is easy to over torque a couple of the fasteners, and it took me taking it back apart twice to find the leak, but that was me over tightening things and not a problem with the product. The company should give torque specs with this, would have saved me a few hours of chasing a leak. Since it was me and not the product it still gets 5 stars.Heat kills Harley's. How long do you want yours to last?6000 miles laterI still love it despite the cheap hose clamps that came with the kit. They will very slowly loosen and a very small amount of oil will start to appear around the hoses at the thermostat and the cooler itself. These need to be retightened every couple thousand miles. I also believe the thermostat does not come on at 185 but a little higher.If you ride your Harley 20 miles at a time then you are not going to benefit from this kit. If you ride your Harley 500 miles at a time you will benefit from this kit.
