ok i just wanted to ask before i go and spend money for nothing.sprocket question: drop a tooth on the front and get more low end snap, i do this on my crotch rockets and is a standard mod. to acheive more top end speed you drop teeth on the rear? i see alot of people are running a 47 tooth rear sprocket. how much gain in top end speed is there? im running stock sprockets right now which i think is 15 front 50 rear.i snapped the stock chain at only 265 miles on it so i may as well just get the most heavy duty set up i can find. any suggestions would be great.
