I have researched oil coolers for some time and there is absolutley no doubt that an oil cooler is necessary for your air cooled V-Twin if you are riding in hot climates. A good oil cooler will reduce your operating temperature significantly and extend your motor life. Nearly all motorcycle manufacturers install oil coolers on factory bikes (except for Harley) Harley Davidson put oil coolers on as standard equipement on their police bikes and race bikes.

I have recently developed and produced a nice high end oil cooler that has some nice retro styling and attention to detail. It is a very nice looking cooler. Cooler has nice bullnose rounded cooling fins and domed end caps. I paid big change for the tooling to do this! Cooler is tested and will reduce opertating temps by 25 degrees. Has an internal baffle system for 100% surface cooling!



Let me know if you guys like it! I did a limited production run and am selling them. The come in three different frame clamp sizes (1 inch, 1-1/8 inch, and 1-3/4 inch). Visit my HOMEPAGE if you are interested or shoot me an e-mail at lrchoppers@yahoo.com This is not a pitch, I am really interested in some feedback to determine if I should make more of these or call it quits.

 

If you want your bike to run stronger and last longer, get an oil cooler.

Since expansion of hot gasses is the source of power, the lower the beginning temperature the more power made.

The hotter the metal in moving surfaces the faster the wear.

It is well spent money whether or not any performance mods are made.

 

looks like ill be tryin the ultracool,my old superglide has 86,000 miles no oil cooler and only one rebuild at 55,000 i can olny hope for the same

 

I installed a momentary press to test switch and a 4 color changing led mild glow light I
In my dash so I know when she's on. The reason for the 4 color mild glow led light is in the summer this fan is going to be on a lot. Personally I wanted to know when she was on and off. Ya can't hear it at highway speeds. I didn't want to see a bright red light on all the time plus at night this could be annoying.

This light cycles by itself green blue red and yellow when the fan is on.

 

I went with the Jagg 10 row low mount and no thermostat. Works beautifully.

 

I bit the bullet and bought an Oil Bud. I liked the idea of the large heat exchanging surface and the fact that its hidden under the bike. My first impression when I opened the box was that it was a quality made piece of American inginuity. Anyone thats concerned about a road rock taking out the cooler has nothing to worry about. I was a little nervous spending so much on an oil cooler, and just taking the word of the web site and the videos on the web site. I don't know how well it cools, as I just installed it today, but after having one in my hand to look at I believe the hammer hitting and shotgun tests on the web site videos are accurate. I think it will get alot more air flow than some would believe as well. I have an ulta classic with lowers. The cooler is below the bottom of the farings and will be exposed to alot of air flow. The one draw back I can see is the difficulty of the installation. The directions and pictures could be a little clearer for starters. I am a decent mechanic an do all my own work unless it requires specalized equipment and I struggled through it a little. I couldnt get the tab that is held in place by the foot board bolt up into position. My experiance is if you have to force something its not right so I called Bud Clarke and he said some of them go in a little hard as no two bikes are the same but he's never had one not fit. He also told me I may have to bend it slightly or cut the corner of the tap off. I had to bend it very slightly and cut the corner off which was easy as it is aluminum and once installed the tab is hidden. It then slipped into place easily. The rest of the installation also took time. The allen head screws that hold the two halves of the addapter together are difficult two tighten as they are hard to access. Once installed I could see its a nice product with bradded steel lines and no hose clamps. If your not confident in your mechanical abilities I would suggest not getting one. I'll find out how well it cools as the summer heats up.

 

I use a HD Oil Cooler and also use Computer CPU Cooling Fans. Computer CPU Cooling Fans as in the fans that are used to cool the computer under your desk. The Computer Cooling fans are 12 volt DC Fans and cost about $5 to $10. They come in all sizes. You can mount them directly on the back side of an Oil Cooler, or under the tank to blow air on the engine. Either way, they work quite well, are remarkably dependable and are very inexpensive.

 

I've tried many different oil coolers (never tried the Oil Bud) and the best one I have found is the oil cooler from a Buel Ulysses that I have adapted to my 09 RG. I have installed fans on it for stop and go traffic. Haven't had a chance to try it in the Phoenix summer heat (110+) yet, but I have run it in 100 degree heat and never got above 220 oil temps. And yes I have tried the Ultra Cool.

 

Jagg 10-row low-mount with thermostat here- 4 yrs & 19k miles & it's still going strong with no problems. Highly recommended.

 

Does anyone know of a fan that can be fitted to the Harley oil cooler?

I have an 11. 103 street glide

Thanks
