58mm piston

[explode64]

Im building a 133cc kx125 and need a flat top or "concave" 58mm piston with 16mm pin. Has any one built a 133 or 144 motor before? What piston did you use?
Iv looked at 80's yz125 pistons but they seem to be a dome top.


(I know there are other measurments that require to be matched to find the correct piston but i need a starting point)

Sorry can't help but it may be possible for you to get the concave machined out or even just made flat if thats easier.

Grab the TKRJ catalog of their website and go searching.
