If you suspect someone still has a bike for sale, look at the date when it was originally posted, then scroll through the thread and look at the last time anybody posted into that thread. If it has been a couple of years, send PM to the owner of the bike. You can do that by clicking on his name and selecting "Start Conversation". By replying to a 2 year old thread, you will bring it up to the top and everybody will think it's new, so we all look at it, think it is another mini bike for sale. Then we all see that someone just replied to an ancient topic that was long forgotten.
Good luck in your search. Happy New Year.
Have fun and be safe.
Oh, and calling names and throwing the Fbombs around, that is a bad attitude for someone asking for help.
