Well here's mine, a '75 KZ400D. I bought it in 2003 for $300, then sold it in 2006, probably should have kept it but some parts were getting a little hard to find. With this being my daily commuter, I was putting about 300 miles a week on it, going through 2-3 tanks of fuel every week. It was pretty reliable for the most part, I kinda enjoyed having the kickstart. I installed a pair of dyna or accell coils to replace the dead or dying original coils and for a little hotter spark. I still have an original Kawasaki air filter for it, in case anyone is interested.
