I see here that alot of folks go from the stock 15T counter shaft sprocket to a 14T sprocket. I understand that this gives the bike more off the line grunt, slightly. I feel like, on my bike, first gear seems very short as it is. Is the use of this 14T sprocket more for the 2nd & 3rd ratios? Also, has anyone gone with a 16 or 17T sprocket? The bike just seems like it has plenty to handle one or two more teeth up front in first and second gear. What are your thoughts?
