well...its going to work. swiped the oil cooler assembly off of a totalled 83 CB650SC Nighthawk. with just a little bit of massaging..it fits. Had to turn it upside down so lines exit the bottom instead of the top. removed those fins so it wouls sit in the proper place. Took 4 mm off the oil filter bolt boss. i will flare the ends of the steel lines and use rubber high pressure lines for now until i can have proper lenght lines made. The cooler itself is going to be mounted on a bracket bolted to where the horn mounts now. and it all clears the factory headpipes. pics to follow when done.
