I like the new stance of the bike after installing the links but I did notice on the highway at 60 and up mph it is very twitchy . I am going to try droping my spring rate to next lower notch and if that doesn't work i will try some progressive springs in the front to help balance out the wieght distribution .
Could it be your tires? Or the air pressure in them? I did install these links about a month ago and didn't experience the symptom you are describing. I like the new height and less sagging.
