    Water cooled isn't about heat management
    for the back of your thighs, everyone thinks
    that when they read "cooled"

    Water cooled is about fuel management
    and noise and epa

    With water cooled you insulate the engine
    in a jacket of water around the cylinders
    which provides more absorption of noise

    Also when it is water cooled the internals
    are cooler so you can run different internals
    and make more power, lots of other tech advantages

    Vrod engines don't make a lot of mechanical
    noise like air cooled hds which they put bigger fins
    on to get more air around it and it gets rid of more heat

    You ride with bigger fins and you feel more heat
    even at a light because it's removing more heat from the cylinders
    and it has to go somewhere, so it's airborne and on you.

    Engines not hotter, you are because it's better at
    getting heat OUT of the engine.

    Had a couple of Honda Goldwings with the radiators and all. They overheat real well in hot weather to. Remember laying on the ground in a camp ground replacing a water pump on a 1500 Goldwing in Idaho once. Gotta deal with the dang coolant levels. I think I'll just keep riding my air cooled Harley for ever. :D

    EPA never raised fuel efficiency
    They made gas so it got less mileage
    The got auto makers to mandate cars to get better
    Mileage
    That should of already done by more gears
    In the transmission
    Gas today has no Store point
    Ethanol in gas gets let's fuel
    Mileage and the ethanol attracks moisture
    And eats things up

    You're right that ethanol doesn't go as far as reg. gasoline (corn producers pulled a fast one over the gov't. on this). But it does have an advantage in higher octane, which means more power from the same motor.

    Alcohol burns hotter and faster than gasoline. E85 is 85% alcohol, which actually increases hp output a bit. You won't get as good gas mileage, but you will feel a difference in power. Still, the internal parts need to be designed for this corrosive brew.

    HRK is right about water cooled jackets deadening mechanical noise better than air cooling. EPA mandates for noise level include this mechanical noise as well as exhaust noise. If a water cooled motor is quieter mechanically, the manufacturer can allow more exhaust noise to meet decibel limits.

    9 years ago, H-D increased the thickness of all engine castings to minimize mechanical noise. We benefitted by getting stronger motors due to this measure for EPA compliance, but they can only go so far in this direction. Stricter regulations usually produces benefits we take for granted.

    Be more open-minded when changes are made. Not everything was better "in the good old days", and would you REALLY want to go back there?

    Honda went way overboard trying to hide all the mechanicals behind plastic covers. That's why they overheat so bad and are a p.i.t.a. to work on.

    H-D, on the other hand, is very proud of their beautiful motors and want to show them off. They justifiably claim "The most beautiful motor in the world". I trust them to make not only a beautiful water-cooled motor, but a vastly more reliable one than any Honda.

    Great pic HRK
    See, Now that's what I envision. Some more C.I.s and that's the Bagger of the future. H.P. possibilities out the wazoo.:D

    Ain't interesting in my motor being any quieter. I just want all the tree huggers and folks that want a water cooled motor to Go and stay in California before they mess something good up.
    For every one person you find wantin a water coold motor. You will find 10 that don't.
    They have water cooled motors already on the market. Why ain't the folks that are wanting water cooled motors riding them instead of a Harley.

    Cardboard, the EPA doesn't make anything but regulations. Everyone who manufactures something for sale in this country HAS TO comply with these regulations. NOTHING will ever stay the same as it was 50 years ago or even 5 years ago. If you want a new Harley, accept the changes or buy something else.

    So I repeat....Do you think H-D will make changes, or choose to go out of business???

    By the way, I'm no tree hugger and I don't live in CA. Must be somewhere in the middle.

    Yeah,I'm sure you've got good points there, but as we all know, there's the way things ought to be and the way things are. Best is to change what we can and adapt to what we can't. And to know the difference between them.:banghead:

    They started Locksmith licensing laws in CAlifornia, all the locksmith were upset for the law and unnesary cost. It went to coloroda and up north and worked its way down the east coast.
    I had already been doing locksmith work over 1/2 of my life.
    It hit here. I had to pass test that people who had not been in the trade as long as me was puttin on.
    I cost a woman in Austin under the private investigaters law her job.
    Needless to say I had to pass test. And get a license.
    Then they revolked my license. I called up and you know how easy it is to talk to the folks with the state. They said I didn't have any Insurance. I said I did.
    They hung up on me.
    I called the insurance company, they said yes you have insurance. We called the lady with the private security bureau and faxed it to her, emailed it to her and mailed a hard copy with a signed copy to her and gave her our phone number and said if she has a problem to call us.
    So I called back and got somebody else. They said I'm sorry, your insurance has to be on State official form 005 or we don't reconize it.
    I asked what, y'all are dictating to insurance companies that their insurance in no good if it ain't on your official form.
    In the mean time I'm trying to run jobs and operate a company. It takes me to do the jobs too.
    I had to find out how to download the form and show the insurance company how to do it and they did. I waited a month and never heard nothin from the state.
    So I called them about my license being reinstated.
    The state said if you want your license reinstated, you owe us 150.00 for your insurance not being any good. What.
    I did work for 2 police officers that started a security and alarm business.
    They said you might as well pay it.
    We moved across the street. And they come in and we didn't have all our records moved. They fined us 1500.00 we tried to fight it and didn't win.
    Its all about money.
    Then after gettin it reinstated. I have to take continuing education and the folks that I'm having to take it from don't even know what they are teaching.
    One class was a all day class on how to put a aluminum glass frame door together. I had to show the person teaching the class how to put it together. They talked about it all day.
    When they got it put together. I asked so where is the piece of glass to go in it.
    You take that out of the old door. What.
    Do you not think if the door got messed up bad enough to need to be replaced that the glass didn't get broke. That is 80% of the reasons you need the work done. Its cause of the glass got broke. Not that the door got damaged. Geesus help these people.
    You have to take so many classes for so many credits so you can keep your license.
    So while I'm taking these classes that takes all weekend and I have to pay for. I can not run calls for the commercial customers who has emergencies and are screaming.
    This is the regulations you are talkin about we have to live with.
    The people that started this needs to be Shot with a Bow and Arrow and gas Poured onthem and tied on a Ant Bed.
    When I gave my company away and come to the country. They don't have a locksmith here.
    I was asked if I would open a locksmith company.
    I said No. It cost me over 2000.00 a year to get insurance and a licence. Not to mention the 1500.00 with the city for having a DBA with them a year.
    That's over 3500.00 year and I have to work for less than 1/2 of what I was gettin in Houston.
    And we haven't even got into the Sales tax folks and the Federal taxes.

    I hope locksmith work goes so high you can't afford to call one. Just like everthing else has.
    And you wonder why when you go to the Harley DEaler you have to pay from 85.00 a hour to 125.00.
    They got to pass these unnecesary cost on to somebody else so they can afford to operate.
    I've been there for 19 yrs and dealt with what should of never been.:gah:
    I can see this country being regulated down the tubes and they have everybody thinking it needs to be done.
    We need a 10 yr depression and nobody having nothin.
    And taking the laws, regulation and people with it.
    If gas needs to be 5.00 a gallon we don't need it produced.
    Why make something people can't afford.

    And I hear somebody telling me I will have to accept the changes and go with the regulations.
    You don't want to know how I really feel, cause I think people don't need to exist that start this BS.

    Yep !
    Know some folks don't want to hear it. But if you ever had a business you learn about it super fast.
    YOu will not git time to lean back and relax if you want to stay in Business.

    And the regulations are killing businesses. Its just you can't see it.
    And its not just that. Its also the city regulations and all to get even more money out of ya. And that don't even include the fire marshall or permits.
    But we got to be regulated.

    Not a good subject for business people.

    We are being regulated to death.
    And you sometimes wonder why companies move to other countries.
    Open a business and deal with it for a few years.
    Then we hear if they don't have change they will go out of business.
    YOu sure about that. HD needs to go water cooled to stay in Business.
    They have Union problems too.
