Hi, I am an owner (2 months) of an FC501 1997 model. Is it normal for this bike to have a tremendous vibration when I use it on the street? It vibrates so much that you get blurry vision. Or, is anything wrong with it? Is there a part that has to be replaced for the engine vibration to be minimized? Other than this, the bike runs perfect and tons of power. Will appreciate any suggestions. Btw, I did a motard coversion. Thank you.
