I need a piston

[cbelk]

Hey anybody out there know where i can get a SYM 250 piston to go into my Carter GTR 250. Also does anybody have jet specs on that same motor. all the manual says is "carburetor." No size, no jet spec, nothing nada zip.
thanks in advance

the stock jets are around a 108 main and a 35 pilot. the carb is about 26mm if I remember right
