Can someone plase confirm bore size as a fraction - FB = 3.062

Is that.
3-1/16
or
3-1/8


Thanks, I am pretty sure its 3-1/16

for some reason 3-1/8 is stuck in my head as the bore size for a stock FB ?? :shock:

it is 1/16th..... ish

if you use a calculator and divide 1 by 16 .... answer is 0.0625

doesn't matter if it's inches, feet or metres....... 1 divided by 16 with a calculator shows decimal answer......


the 3" stands alone with the 0.0625 added....


metric = 3.0625 x 25.4 = 77.7875mm


frats,
