So as not to hijack milkman's oil blowing thread as well as wizz's overheating extreme thread I decided to start a new thread about my oil cooler installation.
Although I have not experienced any overheating troubles with my SR, my recent trip to the mountains two up made me consider adding an oil cooler. A recent ebay offering of a Lockheart oil cooler already set up with the oil lines for an SR got me googling for comparable solutions.
I found a Honda oil cooler for a XR400R 4 stroke dirt bike that is, in my opinion, a work of art. It has a horseshoe shape which is designed to mount under the headlight on the triple tree of the Honda.
That's a nice place to mount it, but the SR uses that area to attach the headlight assembly with a large bracket that also holds the horn. After a close look at my parts bike I noticed a tube welded to the frame, used to position rubber bumpers for the tank.
My rider SR had a little different tube arrangement but it was in the same place. I hacksawed about an inch off each side of the tube (my tube was one piece). To match the width of the oil cooler's rubber mounts (another nice touch from Honda), then drove inch long connector nuts into the tube on each side. I got two quarter inch stainless bolts about 3 inches long and used them to mount the cooler to the cut off tube.
This usage of an existing mounting point saved welding the connector nuts to the frame and positioned the cooler directly in the airflow coming over the fender through the forks.
Using the plumbing skills I learned playing Super Mario Bros, I bought four feet of 250 psi hose with 1/2 in inside diameter and simply clamped it to the threaded sections at the cooler and frame.
I would have liked to use aircraft quality AN connectors, and may at some future point replace this hose and clamp installation with stainless braided hose and trick anodized AN type fittings, but for now the thing works and doesn't leak so I'm going with it.
Overall I think this cooler simply looks tricked out and cool as hell.
