Bend the needle on your factory speedo, take of the winshield and you will feel like your doing 75!!
Seriously, it's not worth it if you are going to upgrade in the next season or two.

In this economy I really like this speed modification strategy. How do recommend pulling the glass face off of the speedometer?
