Well, that's my guess anyway. I made it back to my friend's house after work today, and took a look at the bike. I will post pictures later, but apparently the radiator hose was touching one of the exhaust headers, which combined withseveral other factors set it up for catastrophic failure. I have no idea if the hoses have ever been changed, and the bike is 22 years old, so that alone can be devastating. The fact that I pretty much walked the bike 2.5 miles in standing traffic couldn't have helped. Anyway, the end result is a hole in the hose approximately the width of a pencil.
