No worries, it was my opinion that you should sell it from the beginning anyway
Dirtbikes are generally easy up keep but.... you have to keep up on and not let it all build up at once. When you take an old bike that probably hasn't had much up keep it can get pretty overwhelming once you start digging and finding out that everything is shot from clutch, top end to bearings and forks. You can buy a decent used mx dirtbike for $1700- $2500 or pay just as much maybe more to completely rebuild one that costs $1000 - $1500.
