engine is a 165fmm

According to a gear ratio calculator my 5th (final) gear is a 2.60 ratio not the .98 as advertised.

when i put the proper info in for the 13-48 sprockets (3.69 ratio) with a 27" tire and a .98 final gear i get 166.59mph at 7500 rpm and that is far from correct.
when i use 2.6 as the final gear i get the real 62 mph at 7500 rpm

from what i under stand is 48 divided by 13 is how i get my final drive ratio.
I use this gear ratio calculator for everything else and its always been spot on. Not sure where im messing up here.
