Here is a 12 minute video from the Motorcycle Safety Foundation for you to view.  It is a course in group riding and should be viewed by all.

Watch, learn and enjoy riding with us as we explore the roads and parks of the Natural State.  Chapter A would like to extend a warm and congenial welcome to anyone interested in enjoying the Great State of Arkansas to come ride with us.  There is just so much here to see.

Here are some facts on antifreeze:
Long ago, when engine blocks were cast iron, and radiators were copper, there was a big problem with dissimilar corrosion. Iron and copper are far apart when it comes to their electrical potential. Because of that, they are not compatible and cause corrosion. At that time, silicates were added into the coolants to help mitigate that electrical potential between the two metals. (Don't forget that corrosion is just electrical potential) Remember looking into your 1980's car radiator filler and seeing the white build-up?

The big drawback to the use of silicates is that they are abrasive and rip up water pumps. Not a big deal when your water pump is 12" above the lowest point in your system, like a car. But in a bike, or some construction equipment, the silicates settle out and get into the water pump seals. The pre-1500 wings were particularly susceptible to this as its water pump was the lowest point in the system. Now that radiators are aluminum, and so are engine blocks...The corrosion problem is gone.

The ‘Honda’ antifreeze is also cheaper at the auto dealership compared to the motorcycle dealership. The Type 2 is the long life product and is green in color. It’s already premixed.

I have a question for all of you?
How is it that the boil point of pure ethylene glycol (antifreeze) is 197.6 degrees F. and the boil point of water is 212 degrees F. but, when mixed together the boil point is in excess of 250 degrees F. at ambient air pressure. The use of a pressure radiator cap raises the boiling point even further. (About 3 degrees per pound of pressure). So if we use a 14 lb. pressure cap, the boiling point is raised to about 292 degrees F. Even more interesting is the freezing point: a 50/50 mix of antifreeze and water freezes at a substantially lower temperature than either one of its components by itself!

It's actually an interesting answer!
It's not the pressure alone that raises the boiling point of water. Whenever you mix two pure liquids the boiling temp of the solution will be higher than the boiling temp of either liquid by itself. It also has an opposite effect on the freezing point. The mixture will have a lower freezing temp than either of the liquids by itself.
