My 59 Hilsen just took on a mean shimmy when I removed the front bag and put a basket on a Mark's Rack in the back. Carrying about 3-5 lbs shimmied nastily no-handed, and even shook a bit with hands on bars. I just had the headset replaced from a Tange ball-bearing to a Miche needle top and bottom, and this seemed to not help at all. I had some mild shimmy before, BTW. I also noticed that as I lean forward and put more weight to the front of the bike, the shimmy calms. It was bad enough that I immediately removed the offending rear rack and basket and put my front bag on again. Shimmy, vanquished.
Before - major shimmy: http://flic.kr/p/pS6tUc After - no shimmy: http://flic.kr/p/ntqSPz I recall a post a few yrs back from a fellow who experimented with different weighting in front and back. I believe he found that in his case having any weight in the back caused the shimmy.
