So I bought a fucked up yz250 for 150$. I have little to no mechanical experience but I’d really like to learn by taking this thing apart. Does anyone know where I should start?

So my friend sold me this bona fide yz250 and it seems like such a waste of a beautiful bike. It really has seen better days though and a repair job is probably going to include everything, including a full engine rebuild as the engine seems to be seized. I really don’t have much experience with 2 strokes but I’m determined to at least get this thing to kick over. Where should I start/ what are some resources to point me in the right direction?Things that are wrong with it:Pretty much everythingThings that aren’t wrong with itIt’s not on fireThe tires seem to be servicable via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/e79fnt/so_i_bought_a_fucked_up_yz250_for_150_i_have/?utm_source=ifttt
