I originally tried to buy a full kit from Summers, but they do not offer it anymore, so I basically tried to duplicate theirs. I first bought an oem cooler with all of the mounting bits and bobs. Next were the oil lines, I realized that I could interrupt the long line that runs from the base of the tank down the downtube. Here is where it got tricky: the fittings on the bike and the cooler are metric, but just about all the threaded pipe/hose parts out there are well, to put it mildly, not metric. I had no idea there were so many different types of pipe threads- and after a week long crash course on the web I was given an honorary degree in Threadology. Anyway, it turned out that Earl’s Performance Plumbing had all the fittings and adapters that I needed. Here is the list:
- Oil tank: 16mm female adapter to 6 AN male, and a 45 degree hose end.
- Left cooler: 16mm female adapter to 6 AN male, and a 90 degree low profile hose end.
- Right cooler: 14mm female adapter to 6 AN male, and a 120 degree hose end.
- Crankcase hose: 18mm male adapter to 8 AN male, an 8-6 AN reducer, and a straight hose end.
- 6’ of 6 AN hose.
I am sure that the decrease in oil temperature is also due in part by the extra hose hanging out in the breeze. I needed about an extra 1/2 quart of oil, but I also pumped some out when priming the cooler. Part numbers would vary depending on where you bought the fittings, but that is the catalog description- Earl's Performance Plumbing. No special tools are needed to cut the hose, just follow the directions, (included with the hose), and be prepared to screw up at least once- but it will make a lot more sense after doing it a couple of times. The length was determined by guess-timating, when in doubt, just cut it long, connect the fittings, and then see how much you need to take off. I am getting tempted to to weld on the tee nuts, just have to find someone with a tack welder, (and a steady hand).
With all of the pieces, it was only about a couple of hours, not including my attempt to JB Weld the nuts on. BTW, although that is not the strongest solution, it works "well enough for now" as the oil lines and other stuff surrounding it keep it in place. Someday I'll get around to doing it right- but other than that it is really a matter of pulling the gas tank, cutting the lines and screwing everything together with lots of teflon goo.
