Hi guys! First of all forgive my english, it's not my language. I recently finished the oil cooler installation. It took me a lot of time because i spent a lot of time looking for the parts and how to do it cheap and easy. Finally i thought that using A/C piping would be the easyest and cheapest way. So i got some stuf and some gas hose and went for it. I made somebody weld a pair of nuts on the frame to hold the cooler and i build a bracket bolted on the front of the frame to hold the front side of the cooler. Then i had to hack the stock oil return pipe, cutting it and reusing the nut, as finding a compatible nut is almost impossible here. I got two banjo bolts and made somebody weld the A/C pipe on one of them. I bent the piping using a special tool (a special spring). And cut the hose to proper lenght. I also used some 90 degree elbows welded (tin welding) and some piping for the 180degree part bolted on the frame. Here go some pics, you'll understand better. The bike is going very well. I had to add like 1/4 liter more of oil, i thought it wouldn't need that much. If you have questions, feel free to ask. Miky.
