I did the 16 tooth countershaft conversion today. It improved the motorcycle in every way. It feels like it has an additional 100cc. No more short shifting. Gets away from the line still no problem and the speedo's 10% error has been corrected at least very close. From what I can tell using mile markers I am doing 60 miles per minute. The bike is now running right at 80 at an indicated 80 and it is turning 500 less rpm at the actual 80 mph mark instead of 5000 at indicated 80 that was actually 72!
Now I'm ready to head to California.
