Took mine out to Bonneville from Atlanta, GA and back. It was a 1985 k100 that a guy had pulled the engine from, put a new (4k miles) engine in, swapped all the controls for jap bike ones and sold to me for like $1200. I bought it, rode it for a couple weeks, changed the oil and headed out on a 5,000 mile trip without a SINGLE issue.
Bike was ugly as sin, and took a looong time to bond with and get used to but I wish I could have afforded to keep it at the time. I'll have another one, some day.
