This is the best thing I have had in awhile and makes a huge difference.

Simple to bolt on. Took about 15 minutes. Notices right a way the throttle response and within my next full tank of gas the the better mileage I was getting with this upgrade. Great product. Does exactly what is stated. I want to install one in all my rides.
