38T

This mod is straight forward. I am now running 19T front and 38T rear with ratio of 2.0

With the power upgrades in the bike, this ratio is more rideable and still able to do a 1st gear power wheelie at 6k rpm. 

The chain was only reduced 1 link to have little longer wheelbase. 

Intentionally chose gold link as its easier to see when lubing chain.
