my 07 was stupid hot,90 and traffic after 15 minutes it was so hot it wouldnt idol,a tuner did the trick for me.

 

I run HD premium w/thermostat. All coolers should work well with airflow. Stopped in traffic, I imagine the units with fans are the only ones doing anything. Local Las Vegas and Henderson patrol officers shut their bikes off when at extended stop. I do the same. Next chance I get, I'll see if they're running coolers.

 

This is my first bike with an oil cooler on it(HD Premium OIl Cooler), had it installed when I bought the bike last year. I rode in 95+ degree heat and also in heavy traffic and this is the first time I have not had any overheating problems at all. I also use synthetic oil. It's made a believer outta me!

well i have the ultra oil cooler also worked great for me but even when it wasnt that hot my bike got very hot. then i bought the thundermax and boy did that make the differance.

 

I've run the Jagg 6 row oil cooler and the HD premium oil cooler. Both had thermostats, neither had fans. It seemed the Jagg worked better to me.

 

I run a Jagg 10 row on my RG. Works consistently but like all w/o a fan does not do much when stopped in traffic. Have not seen oil temps go above 240 since I did the installation a year ago. Runs about 10 degress cooler on average since adding the kit.

 

I have an 07 FLHX live in Phoenix AZ where 110 temps are common in the summer, I never had the idle problem but added the HD cooler and it lowered the temps about 10 to 15 degrees. This gave me a little more piece of mind on those hot days.

 

I ran the Jagg 10 row low mount with the bigsky fan kit and loved it, the new bike came with the Harley oil cooler on it but I won't really know how well it works until the summer

 

I was gonna put on the HD Cooler last summer, but after speaking with a guy that I know that has one, I changed my mind.

He says that his Ultra fully loaded with wife and their gear going 80-85 down the interstate, the temperature gauge still hits 300 degrees.

That's when I decided to go with the Oil Bud. http://www.hotbikeweb.com/tech/1003_...ion/index.html


They guarantee a 35 degree drop, so even at twice the price of the HD I figured that was the way to go. It does not disappoint.

 

I used the Jagg 10 row lowmount, it worked very well for me. Oil coolers work, period. Different manufacturers and models may work to a slightly greater or lesser degree, but they all work. You'll find a lot of folks that will argue they don't work for many reasons, one of the big ones is "they don't do nothin' when you aint moving". No they don't perform to their maximum cooling potential with no air moving across the fins of the heat exchanger, but they don't completely stop shedding heat either. Consider this, even if it did stop working completely when you come to a stoplight or get caught in traffic, your operating temp will still be lower when you stop moving, than it would be if you didn't have the cooler installed. So at least your temps will stay cooler for longer. Avoid looking for answers that quantify the specific temperature value of the results others have experienced; its like predicting the output of a fantasy motor build, way too many variables. Pick a cooler, any cooler, and like its name suggests, your oil will be cooler. It sounds like you are already entertaining the idea that cooler oil would be better, so I think you will be happy with a cooler.
