Sounds like you have a mess to fix.

Don't be scared to look at buying OEM parts. The price of the case half might be up there, but the internal parts are not really all that bad. A few years ago I repaired an exploded YZ125 tranny and replaced almost every single part in the tranny and shift mechanism for around $800.

E-bay is a good spot to check for the case half but can be a crap shoot. They usually go for about $150 or so for a good case half on E-bay. I think the OEM price is around $425.

Here is where I buy most of my OEM parts - [Only registered and activated users can see links. ] and they are in your neck of the woods (Penn). I have bought several bikes from these guys, too.
