I just picked up an '81 GS1100e. Runs great and looks great but when I took it out on the road I noticed that there seems to be a bit of a sway on the straightaway. Say, I'm just coasting along at 30 MPH in the city on a straight road. It feels like the tires are wanting to sway from side to side with sort of a rocking motion. Tires are pretty much brand new. Any other suggestions for what might be the cause? I had a Honda CB 750 that had somewhat similar issues due to the the crown bearings being mistightened but I don't know that this is quite the same issue.

Front is fine. rear is on the low end of the range and I'm planning to experiment with some higher pressures to see if that helpsOriginally posted by turbojonn View PostComment

All good suggestions, so far, but I will add: check the steering bearings. Not just the tension, but overall condition. Raise the front wheel off the ground, see if the wheel turns smoothly from side to side. Especially notice if there is a "notch" in the motion as it crosses straight-ahead. If you feel that notch, it's time to replace the bearings.
You say that the tires are "pretty much brand new". Is that according to tread wear or the date code? Don't trust tread wear to date the tires.
