"Down a gear" is probably the correct gear. The gearing seems tall to me as well. For example, I don't shift into 6th unless I'm over 65mph. Changing the front sprocket from 17t to 16t is a popular modification. Based on what I've read, the stock fuel mapping is biased towards emissions compliance. The 16t supposedly makes this less of an issue and modified throttle tubes with a progressive action are popular. I've largely gotten used to it but when the weather gets nicer, I'm going to visit my local tuner and and see what he can do.
