A friend of mine and his wife went down yesterday on their Ultra (not cvo)in the NC mountains. He had forgotten to increase the rear suspension air pressure before they left town. He went around a sharp, but flat curve and his floor board grabbed the payment and his front wheel went airborne. Fortunately they only have scraps and bruises as they weren't going very fast. I post this as a reminder to all of us that weight is DEFINITELY an issue especially when your tour pak is full and you have a pack on top of that. My friend is a very experienced rider and has over 36,000 miles on this Ultra. Tbone convinced me to run 40psi minimum when riding 2-up, regardless of what the book says.
If you do not have a HD air pump get one. It's the best $40 I ever spent.
