125-200cc Help Identifying a WR125 Top End

I recently purchased a 2006 WR125 and I need help identifying the top end. The cylinder needs to be replated and the piston replaced. Where can I buy a replacement piston?

Thanks for the help,
Jason

That is the STD Mahle piston kit from the '75-'76 GP175. George at Uptite uses that piston in his big bore kits. There should also be a spacer plate between two base gaskets on the cylinder and two spacer rings on each side of the rod carried on the wrist pin. You need to contact George about the piston kit and the re-plating. The guy George uses for the plating does a great job.

Thanks for the help Wallybean! Yes, There is a 1.5mm cylinder spacer with two .8mm base gaskets and two spacers on the wrist pin. What is the best way to contact George?

Just call Uptite Husqvarna. He always answers the phone. Great guy.
