comes std. on the touring bikes
First thanks Neal for all the help and pics of oil coolers, here is what I came up with. Its a cooler for a touring bike PN 26115-07, with a couple of billet frame clamps PN 91147-02, a few cuts on the Ironsmith, some mig welding, beadblast, several bad words, a little Fusion black and its one the bike

Ran it around town yesterday in 65degree ambient temp, the oil stayed about 215 on the hwy it was down to 210. Today its suppose to be up to 75 thats where I had my 260 in town and I want to see what it is going to do there now. I did change the oil to Royal Purple 20w 50w the same time I put the cooler on, 500 mile servicel. I have found in the past, with a thermal cam that RP syn will cool the engine down about 10 degrees over HD syn. Its not a good pic, hey I do good to be a wrench Im not no photographer for sure
PS you can see I also rotated the horn bracket to point the cover forward, use a little of it like the old scoops we use to put on the Dyna's after hop up. You would be surpised to feel the air flow it puts inbetween front and rear cyl. every little bit helps.
