A little while ago I stated to get a vibation in the front end. I first noticed the mirrors were vibrating and then noticed it in the grips and my windshield I could see was going up and down. I thought the front tire was cupped but did not appear to be but replaced the tire anyhow. Still the same. Now what I have discovered that my front forks seemed to be jammed or stuck when fully up. I have to actually put on the front brake and push forward to get them to work. This seems to be the problem. Has anyone out there had this problem and how did you resolve it.
