The Suzuki GSX-R1000 engine comes with an oil cooler, but has short hoses as the cooler is mounted right in front of the engine. I cut off the flexible hose section from the tube and flange that mounts to the engine on each OEM hose assembly. I then purchased stainless steel AN-10 bung fittings and turned them on the lathe to fit over the OEM pipes. These were then welded together. The welding was smooth as butter because the metal types matched well. I then made up a pair of hoses to run from those fittings over to the oil cooler and back.
