Even with the power up these bikes run a bit lean. Add a pipe and pre filter air box mod and its even leaner. The tuner will allow you to ad fuel all through out the rpm range or if you're low on fuel and miles from gas, you could lean it out. You'll get a better throttle response, more power and cooler motor. Call JD jetting and they'll explain it very well.
