I have a vibration in my the front end of my 93 vfr. I only notice it between 45 and 65 mph, below or above these speeds it is not noticeable. I have had a few opinions about what is wrong, bad tire, bad bearings in steering stem, wheel out of balance. I had the wheel checked for balance and it is spot on!! I would like to check the bearings in the stem but I am not sure how without tearing it apart because I do not have a center stand, just a fork and swing arm stand! How hard is it to take out that stem to check those bearings?? Any info would be appeciated
