Well, I just rode the bike for the first time with the 14:1. I have to say, I love it. It turned the bike into a torque monster. It trys to pull the wheels in almost every gear if you hit it at the right time. To me, it feels like it makes a lot more torque at any point in the rpm range. It doesn't feel a whole lot faster, but it definetly has more grunt. I was also running in sand/ soft dirt, on the stock tires, so the lack of traction could make it decieving as well. I can't wait to get my paddles on it, and go run some hills. That will be the true test.
