Ask the Editors: Get Me More Juice Through My Sprockets
Do keep in mind that an air-cooled 110cc will not offer much in the way of breadth between its 3 gears no matter how much you affect the final gear ratio (altering the two external sprockets).
That being said, you may be able to eek a bit more range out of them by using the following rule of thumb:
Gearing a quad up or down: Up refers to a taller gear ratio, which translates to more overall speed throughout the powerband. Gearing a machine down means a lower ratio and hence harder acceleration at the cost of top-end speed throughout each gear.
So how does one go about gearing up or down? Simply this:
Less teeth on the rear sprocket or more on the countershaft = gearing up.
More teeth on the rear sprocket or less teeth on the countershaft = gearing down.
You will want to gear your ATV up.. Purchase a sprocket with less teeth on the rear or more on the front (countershaft); or some combination of the two depending on how it feels to you in action.
