Good point. tcmb has 14 and 15 fronts, and 45 and 39 rears. He has tried:
45/14=3.21
45/15=3.00
39/15=2.60
He could try:
39/14=2.79
for free, getting back a little torque, at an unknown cost (if any) in mpg.
A front sprocket is $10-$15. If a 16T will fit on the bike, he can try 39/16=2.44. Since he is rarely going over 1/2 throttle with 2.60, there's a good chance he will find it OK.
