Purchased my 87' K75C/T two years ago. Bike had been laid down. Have always had a problem with the front end bobbing up and down around 35 mph. This could be flat spot in front tyre from being on the side stand for so long, but two other things are also evident: 1) Front tire wears faster on left of center, and 2) bike has always required slight pressure on bars to keep it from veering right... becomes more evident as tire continues to wear. If I remove my hands during travel, I must lean at least 30 degrees to stay on a straight line.
I am guessing that my forks were possibly knocked out of line before my purchase. How might I go about making sure that my forks and the cross braces are square? Welcome any comment.
