Is more teeth on a sprocket better?
Adding teeth to the front and rear sprockets have opposite effects. Installing a larger countershaft sprocket creates higher gearing, while a larger rear sprocket lowers gearing. Similarly, a smaller front sprocket lowers the gearing while a smaller rear sprocket makes the gearing higher.
What does a smaller back sprocket do?
Substituting a larger front or smaller rear sprocket lowers the ratio (sometimes called "taller" gearing), resulting in more speed for a given engine rpm. Likewise, a smaller front or larger rear sprocket gives less speed for a given rpm ("shorter" gearing).
