I like it the Valair a lot! It's adjustable which is nice and it is a heavy duty replacement. The pedal feel is not harder than the stock pedal feel. The Valair comes with braided line and works very well. The starter switch isn't hard at all to remove. I did have some issues with the installation on mine, but that was because of fuel isolator being in the way! (my fault) The Valair is less money, but like SBC said their HD unit comes with the starter switch and fire wall mounting bracket, the Valair doesn't. Having said that, for the price you cant beat the Valair IMHO. I got my Valair here
