I perform upgrades to perfect a slightly imperfect (due to EPA reg's) work of art and engineering and to tweak it to suit my needs and idea of perfection. Then I take it out on the road and test the limits and performance of the upgrades. Why buy upgrades that you will never use, nor have the will to use, if you do not exceed the speed limit? So, what is the point? I do not understand, it is illogical. So you are going to build a bike that does 170 MPH and a sub 3 second 0-60 and never exceed the speed limit?
You must own a CVO if your Harley has two thirds the torque of a Rocket. So, what Harley do you own?
Don't forget the intake end of things. One can improve that easily by removing the under seat snorkle and installing a $67 K&N filter. Visit this website for accessories and performance parts;
