72 125 Piston size

[paul]

Hey, The top of my 72 125 piston says 53.93. Is this standard bore? Hard to believe after 35 years that it is still useable. Does anyone know what the clearance should be between the piston and bore? Thanks much for the help, Too Tall Paul

Thanks, it says stock bore is 54 mm and with clearance that would be right. I was told that it had been bored but that is not correct. guess thats better than being bored to the max huh. TTP
