you can try at somebody who´s in a motocross bisnis, maybe he knows somebody who is a dealer for this husqvarna. i´m from croatia and i has have the same problem but i found a dealer here in croatia and now it´s ok. some parts are the same parts like in husqvarna wr 250 2003. or 2004. year. also you can try search at MV augusta or Cagiva - same parts. if you searching for piston or cylinder i´m sorry, i dont know. i had problem with that, my mecanic man put me something into cylinder and now is not piston like before 71,5 mm now is 69,995mm from husqvarna wr 250 2003. and it runs like hell. it´s ok. i´m sorry for bad english.
