hey everybody so i have quite a larger tire on the front of my bike about 130 and it seems my springer when i get up around 80mph it gets a lil jumpy is this due to the tires size or do i need to adjust the front end? thanks for the help!

 

Hope this helps..Toward the end of the article may be what your looking for.Not sure.
