So basically, a friend of mine has an 80cc Honda Crf with a seized engine. I offered to buy it from him for $125 but I needed a couple opinions on if it would be worth it or not.. I'm not a mechanic by any means but I know a few things and i was hoping someone could help me out. I want to try to unlock the engine so I can get it running so if anyone could help that would be great. Also, is it a problem that I need a lot of money to fix?
