Yes, I'm there. Just didn't check this post for a while.

 

Bit the bullet and got me the 07 Street Bob (with forward controls).

Every bit of engine heat is welcome at this moment, since temperatures dropped to lower sixties here and the constant rain is also getting a bit on my nerve.

Sigh..., that's the consequence of living in Western Europe, I guess.

Anyway, thanks for the help in my decision,

Regards,

awesome on the new bike. post some pics when you can .

 

Hi , I just gotone inapril a 07 FXD New Jersey was very HOT this year I was running in 95 to 105 degree heat nice runs about 100 miles a day and It run OK. No problems I have on it 2900 miles now still running great .

 

I have been doing a lot of research on this issue since I bought my 07 FXD, which is my first air-cooled engine. I am about to regurgitate what I have found in books, magazines, websites, and from mechanics...little of this is from personal experience. So for what it is worth, here goes.

First, the Dynas don't seem to have as much of an issue with heat as the touring bikes, since they are lighter. I have been riding my bike here in the summer heat and humidity of Missouri, and the heat coming from the engine hasn't really bothered me. But yes, air-cooled engines are hot,and they have gotten hotter with the newer EPA regs. I have been following articles in several of the magazines, where they actually measured the heat difference between stock TC96 engines and older engines, and it was a big difference, according to them the new motors generating about the same heat as a race bike. Except race bikes are not built for longevity. So the extra heat could be a factor in long term maintenance for different parts on the bike. Things wear faster when they get hotter...seems to be a reasonable assumption to me. The bike is designed to run leaner to meet the regulations, and if you add bigger pipes and an air cleaner to let the engine breathe better, it leans out even more. I certainly believe this is so from the results I got with my bike after having slip-ons, the SE air cleaner, and the download installed, since it started popping on decelleration, which is a sign of leanness. So from what I havelearned from several sources, one of the best ways to cool the engine down is to install a digital fuel processor, or a tuner, to adjust the fuel/air ratio. Which will also make the bike run better. I have ordered the Cobra Fi2000R O2 H-D unit for my bike, should be here in a few days. This is a plug and play unit, which can be unplugged rather simply, if the bike needed to go in for warranty work perhaps. It doesn't change out anything on the stock bike, and works with the closed loop technology. I will post my results once I have mine installed and running for a while.

The other thing that can be done is to have an oil cooler installed. This was more expensive than the Cobra unit, and the mechanic at my dealership didn't believe itcooled enough to make it worthwhile. I have read somewhere that it should cool the oil by about 25 degrees. I decided not to install one yet, since the Cobra unit is supposed to drop the engine temp by about 50-75degrees. We'll see.

Hope some of this info helps, along with a lot of what the other posters have said.

 

These are big air cooled motors they get hot any time they're not moving.I have changed to synthetic oil,wrapped my head pipes and added heat shields.My bike has also been tuned on a dyno which helped quite a but it still gets uncomfortably hot any time you have to sit still for more than about 30 seconds.Then again temperatures have been in the mid 90s here lately which will make anything air cooled uncomfortable.

 

'07 Bob and no heat problems. No more heat on the legs than my other bikes (both non-HD, and one is water cooled). I had a Buell for awhile - want to talk about engine heat? My right **** cheek and thigh sizzled to a golden brown during every ride (even continuous, non-stop-go).

 

I test rode an '08 XB12R last week in ~90 degree heat. Both freeway and stop/go traffic. I've owned several Buells before but I don't remember any of them throwing off heat like that '08 did. Not only were mythighs getting burned, but when the fan kicked in, heat was blowing up from between the seat and frame -toasting my gnads into crispy goodness. And keep in mind this was with the Buell moving at a pretty good clip. At least the Dyna doesn't get too uncomfortable except in slow traffic.

 

Do you have any results from installing the cobra yet?
