I have a 1990 yz250, i was riding this morning and everything was goin fine, then all of a sudden the bike lost power and bogged down i had to keep tha gas reved up to get it back home. I shut it off and checked the plug and it looked fine. I tryed to start it again about an hour later and it made sum weird knocking sounds then the kickstarter seized up. Im thinking it could be a crank bearing or either it just overheated and seized, need sum feedback

Probably be better off just opening up the engine and having a look... You're most likely going to have to tear it down anyway.
