Some observations on head shake. First I am no engineer, just very experinced rider. I have approx 500,000 miles and 45 years on every thing from dirt bikes to goldwings.
It,s been my experiance that when I had a flat on the rear at speed ,upon slowing down thefront went to shaking violently from about 40mph on down Also on my goldwing the final drive destructed,the first symptoms was a high pitched whine that sounded like it came from the dash area.Latter it sounded like I had a FRONT bearing grinding . After tearingit apart three times to check still didnt find anything wrong, then went to the rear and checked under the final drive and saw ground metal. The point I am trying to make is that sound and wobbles are transmited from therear. Also my 01 had head shake from the first monthI bought it new. I now have almost 100,000 miles on it and no head shake. In trying to solve it I changed types of tires and brands,new steering bearings, changed front springs,sometimes after a new tire the wobble would go away for aperiod of time. Also replaced both wheel rims. At 62,000 miles I had to change the rear brake rotor the wobble stopped, This doesn't make sense unless the rotor was out of balance. I think the reason that some rear tire changes stop the head shake is that they were balanced better than others also when mounting, the tire is placed at a different point on the rotor either compounding or correcting the out of balance rotor. Sorry if this seems rambling, but don't discount the fact that seeminglyfront end problems may be in the rear Sledge
