That was totally uncalled for...

Ken

It's OK, Ken.  He readily admits he's full of chit with every post ...

You stating something is "obvious" may make you feel somewhat superior

It's ok Ken, I thought the gentleman was being relatively delicate there.  "Somewhat superior" is far from the worst thing I've been called (today). 

Of course I think he's understating it just a bit.  "Somewhat" superior?  Really?  And I try so hard to earn better....

LOL!

I'm just in a MOOD... It's effing RAINING here AGAIN today. I feel like I live in a damn rain forest this summer. Grrrrrr...

Ken,

I have the weather channel on every morning as I get ready for work basically to see if its a suit day, or a polo day.  I find myself watching the weather now for the southeast and I say "poor Ken, its f^%$##*&^^ raining again !

Every day I ride this summer, Honey Badger and I are both WATER COOLED!

That's sort of on topic...

Amen to that Brother Ken.  It's been similar here.  This past week was the first time I've got to mow in about six weeks where rain hadn't so delayed the mow I had to cut it twice (higher then lower) just to get the damned mower through the yard. 

To keep on topic my mower is liquid cooled.  I occasionally spill beer on it when the yard is bumpy.

Well I still say that the heat off the rads is going to be a issue. They show a 60 MPH heat graph , thats great, however lets think 110 temps in the traffic where you might get up to 35 mph then what.. At least you can warm your lunch in the compartment..  heat has always been an issue in slow moving situations not hwy speeds.

Will go look at one this weekend as I think it would be a great mule for testing.. See what my 12 SG is worth HA HA

OK my 5 years are up so let's talk about water cooled HD heads. This was done along time ago and then put on the shelf. I was involved with it back in the 2005 time as I recall. Back then it was called Precision Cooling. It was developed for 2 options, water cooled or oil cooled. The oil cooled version of it came out on the XL line and the water cooled never made it out. I was told that at the time, Willie G. at HD stated "there will not be a water cooled HD as long as I'm here". Well I have no way to know if the statement was true or not but he is gone and now we have the water cooled head that was done way back when!

The heads themselves are interchangeable with the current air cooled heads. All the components will swap between the two from what I've been told and I can assure you the prototype stuff back in the day did. Now, its called Twin Cooled instead of Precision Cooled but it sure all looks the same to me as it did back then for the most part. The new lowers I hope solve some of the old test issues but we will have to wait and see on that one. The compression is the same for both the air cooled and water cooled 110. The 103 gets a slight compression bump 9.7:1 air cooled and 10:1 water cooled. The water cooled 103 also gets a different camshaft from the air cooled 103, not sure about camshafts on the 110 engines.

Does it work, yes it did back then and it worked nicely but rider comfort (heat) didn't really change any with or without it. Maybe the new shape of the lowers will help with that but like has been mentioned before most would remove the lowers in hotter weather and that's not an option with water cooled. When your sitting still in traffic I doubt that it's going to be any cooler and at highway speeds was never much of an issue anyways IMHO.

All new ECM and code in them and were hard at work on that already. Hope to be able to get it done quickly.

You are 100% correct. The design and prototypes were made in early 2004. Limited testing was done in 2005 / 6 and shelved. Extensive testing started 4 years ago. Yes, they are interchangeable.
EO testing started in my last year at work at EPA and engines presented passed EO compliance.

So... now when the bike gets hot sitting in traffic we'll know right away when it boils over!  Time to start lobbying for lane splitting in states besides California! Or maybe add some cooling fans.

Maybe there is some advantage to using oil to cool the heads instead of water...?

If you're past a required confidentiality period and do feel comfortable speaking more on the topic the highlighted sentence above seems the next question from your remarks.  What were the issues?

There are cooling fans located in front of the radiators...

I like Wet Head better than Hydro-Glide. We've had Flatheads, Knuckleheads, Panheads, Shovelheads, Blockheads do why shouldn't it be the Wet Head ?
