Here is my list. Most of the same issues except for the high mileage bikes. 1) Not every bike is worth $3000. If your bike is missing all its plastic, is not currently running, is not tagged or inspected, made before 1995 (with rare exception), over 90K miles or any number of other items it’s not worth what you want it to be worth. Sorry! 2) Do you have a title? A street bike without a title is only good as a parts bike unless you go to the trouble of getting a bonded title. I have done this and it is not cheap or easy. Often the process and the expense renders even a nice bike valueless. If it’s a non-runner, needs work and has no title it’s crap. Technically you can’t sell a bike without a title anyway but idiots try. 3) Don’t call it a classic that is “going up in value” unless you actually have a classic that’s going up in value. Very few bike are actually classics. If you have a classic you will know it. No one is beating down your door for your 1980s Honda Twinstar. The truth is older bike, especially older Japanese bikes are next to imposable to find parts for. If you plan on actually riding a lot you don't need this headache. 4) Cutting the rear frame loop off a bike and using a few paint bombs on it does not make you a custom builder and does not make the bike you ruined worth $3000 see #1. 5) Don’t post “it was running when parked.” They were all running when parked at some point. Yes it could need the carbs cleaned. It could just as easily be missing third gear and have a valve stick in a piston crown. If it’s running, show me. If it’s not see item #1. 6) Putting clubman bars on your Honda Twinstar may make it a café racer but it does not make it worth $3000 see item #1. 7) If your bike has over 90,000 miles, I am sure you trust it. I don’t and it is not worth over $3000 I don’t care what it is. You used it up. It’s done. Even BMWs wear out. In fact BMWs that have not had the regular maintenance wear out really fast!
