i was thinking about a 12 front sprocket i know this will help top end but how much ? and does it affect your bottom end i have heard it realll hurts bottom end
if u put a 12 tooth front on it does the oposite of what u said. It will give u alot more bottom end and will take about 3-4mph off top speed. U will get off the line alot quicker and go threw gears quicker as well. It might be a little to low of a gearing with 20in rear tires but u could try it
