Hey Kanook. Glad to see you started a thread. I'm excited to watch as you get ready for V2R.
I'm happy to help with the repairs on the 450x if I can. As I said I have the tools to split the cases if required, though I bet it's just the shift shaft that's bungled up.
You can borrow my wheelset and spares box for V2R if you want. I have a nice set of spares from Baja that would be nice to drag along just in case.
