I just got an 86 lt250 it does not have a piston so i need to figure out the bore but i dont have a metric caliper and i am coming up with a hair over 2.76 inches but i cant seem to figure out what the stock bore is in inches if someone had this information it would be greatly appreciated thank you

Stock bore 70mm = 2.7559"

To get the size you measured in metric, multiply by 25.4. So 2.76x25.4= 70.1mm
