I have recently aquired a 1980 yz50. It needs a piston and rings. The question i have is, Does anyone know if the older model or any year pw50 piston and rings or other bike would fit in this yz50? I need a .025 over bore piston and rings. I have heard pw50 can but want to get some opinions from some who know what they are talking about. Thanks.
