76mm Cr250r pro-x big bore

Can anyone help!!!! I am having a hard time finding a piston to rebuild my procross big bore kit for my 00 cr250. The cylinder bore is 76mm. Please help, " I WANNA RIDE"

Try ESR racing in Pismo CA. They do a lot of big bore Honda 250's.

i have a book with all pro-x pistons and i can not see a piston bigger then 66.37mm

I took it to my local dirtbike shop. He said its 76mm. The piston is a wiseco. The serial numbers are visible its 84 W. Then I called wiseco and they said its a special made piston that I can only get through pro-x. And of coarse I can't contact pro-x. ???
