With 15 front and 42 back it goes to 2.8 : 1
So you can see where the most gain is, and also the least cost and work.

Absolutely right if the 2.7 ratio does what you need it to. I tried that initially and it was definitely a quicker job. I ended up opting for the rear sprocket swap a short while later because it was still revving the engine too hard at the higher speeds. The 2.53 ratio I ended up with has been a good balance for me so I can still get decent low end and cruise at 60 more comfortably. These smaller increments seem to be a bigger deal when we’re working with only 14 horsepower
