all of these parts came from a 1974 Yamaha MX125a
engine serial number 402-00029X
these are all good usable parts. parts may have rust and minor defects, but all are usable parts.
many of these parts will interchange with other year MX125s, but not all will. i don't know what interchanges
Ask questions. I can provide as many pics and answers as you need. I am not the expert. YOU ARE THE EXPERT.
I combine shipping. I have other Yamaha MX125 parts up for sale. buy a bunch of it.
