I went riding today and tried to top it out a couple of times. When I got to about and indicated 180 the front end started to wobble a little bit. So I backed out of it thinking maybe it was rider error or road surface. A little later I got into it again and again at about 180 I get this wobble. It's not real bad, but it's bad enough to keep me from staying in it. I have topped it out several times before with no problems. I checked the tires for flat spots and anything out of the ordinary, but all looks good. Anyone ever had this happen? Any ideas? Thanks in advance, Mitch
