Default How Fast Do I Need to Ride to Keep the Engine Cool?

I hear alot about avoiding sitting stopped in traffic but how about slow cruises? I do alot of city type driving that doesnt get over 30 mph. I remember reading (here on the forum) that you need to be going around 45 mph before any real cooling takes place.

Any ideas?

Don't lug the engine. It's much better to keep the revs up than to lug the engine during city riding. Not much else you can do with an air cooled engine and nothing you can do setting at stops.

Well, a lot depends on the ambient temperature to calculate the effect of speed it should be possible to equate it to the effect of wind chill for various wind speeds and ambient temperatures to get the overall effect of reducing the operating temp of the bike. Let's assume an operating temp between 200 and 240 degrees based on HD's claim for oil specs. Use the calculator on the site below for wind chill and play around with various speeds until you get your desired effect for a given ambient temperature:

This is the Dark Side of this forum...
If you take all the posts in this forum to heart, the message is that you should buy a Harley becuase they're better than any other bike on the planet. Then you should replace every single part from the handlebars on down.

Your bike was designed by real engineers. Harleys are tested under brutal conditions. If you can survive the riding conditions, chances are your bike can too.

&nbsp\\;I say as long as your moving your ok,,and if you have to sit somewhere for 2 or 3 minutes ata time you should still be ok for anywhere 30 minutes to an hour depending on temp.
&nbsp\\;
that's just my take.. Very well put splatter!!

Today it was about 100 degrees in the sun, 94 in the shade. I was sitting at a light for about 2 minutes and could feel the heat getting hotter and hotter. I was so happy to see the green light.
