First of our "spotted on Craigslist" items is this Kawasaki KE 100 dirt bike. I love bikes like this. Simple and fun (and cheap!!). The owner of the bike didn't provide much info except for the following:

2000 Kawasaki 100cc dirt bike. Can go street.

Here's the link:  http://nashville.craigslist.org/mcy/1558866834.html

and a photo:

I did bit of google 'ing and found out this info:

"The KE100 is powered by a simple 99cc air-cooled, two-stroke engine with hi-tech features such as Kawasaki’s exclusive Electrofusion cylinder that offers efficient heat dissipation and abrasion resistance, and a maintenance-free capacitor discharge ignition (CDI) system. Kawasaki’s Superlube oil injection system eliminates premixing fuel and oil, a common procedure with many two-stroke engines, and delivers the precise amount of lubrication to the engine for greater reliability.

The frame is made of high tensile steel and has a steel engine guard for off-road protection. A U.S. Forest Service-approved spark arrester assures the KE100 access to many wilderness roads designated for licensed vehicles.

At 187 pounds, the KE100’s light weight and seat height of less than 32 inches make it simple to ride and helps give new riders confidence. The light weight also makes it easy to haul and has made it a favorite camping companion."

Good Luck with the sale there friend. If I had the cash laying around I'd love to add it to the stable.
