i have had an ultracool on my roadking for about a month down here in south texas. several rides have been in 100 degree heat. i can feel the difference on my legs. the fan is a big improvement on any oil cooler. hopefully, harley can do a retro fit and add a fan for all the coolers they have sold.
They do help. I don't have the new and improved version just the one that was put on the bike in 04 with the 103 build. They have to be even better with a fan.
Seems to be running hot after my 103 build. Was considering installing an oil cooler. Any feed back do they work, how difficult is install, which one us best.
Thanks
Adding an oil cooler is great ,but have your tune checked too.The bike shouldn't be running hot.Make sure it's not running lean & damage the build.Check tune then add oil cooler.Both help cool the bike!!! What temps are you seeing now???
