I have to replace my chain and sprocket set. When I ride my bike it shifts a lot different than the cbr 1000f I used to have. There's no sweet shift spot. The gearing seems too short or the next gear up is not synched to be a smooth transition. I want to add a tooth to the rear. I got better mileage on my cbr because of the higher top end. Does anyone know of a good touring sprocket combination?
