I'm curious how to find out which piston my 125sx has.
A or B ? Is there a letter designation on the head?? Would the squish gap tell me this? Do I need to break it down to tell?:think

Often its just printed in ink on the top of the piston...so looking at the piston may not work.
There should be a stamp somewhere on the cylinder itself.
