Thank you, Norm! For this old video. (notice I didn't, scream.)

So, would you suggest that if we have high-speed weave with our bikes should we,
A, Check for 'squared-off' rear tire?
B, Increase or Decrease Front Tire Pressure?
C, Increase or Decrease Rear Tire Pressure?
D, Increase or Decrease the Rear Shock Spring Preload?
E, Increase or Decrease the Front Fork Spring Preload?
F, Slide the Front Fork tubes up or back down ( lowered for short legs) Thru the Triple Clamps?
G, Move some of our Touring Weight Forward?
H, Check our steering bearings, Lube and Preload?
I, Multiple combinations of all of the Above?
J, Slow down and enjoy the scenery?

Thank you again. It can be a Confounding / Complicated Problem. And sometimes very Simple.

IME, tire pressure is the place to start but often overlooked. IME, the front fender is innocent. Slowing down isn't an option because those kids on the CBR600RR's will catch up. ;-)

Unfortunately attractive women take the same view. ;-)

My '01 has a pretty mean case of wobble or weave at 75 mph or so. I'm still trying to identify the issue. Different tires change the speed it occurs (more knobby, wobbles at lower speed like 70).

I've tightened the steering head just a smidge, following the directions posted here, didn't seem to change it. This winter I changed the oil in the forks but found both forks to have the same amount of oil, and probably real close to the proper amount.

I check the tire pressure pretty often and keep the tires inflated to their posted values rather than kawas.

I just installed a fork brace but haven't had the chance to test it on the road yet.

I finally got to test my eagle mike fork brace. My klr had a bad wobble ~70 mph that would get progressively worse if I sped up or could happen at lower speeds in windy conditions.

Took a 400 mile trip yesterday and never experienced the wobble. Even managed to get the beat up to 100 for short stretches and it felt solid and planted. The fork brace may not really be treating the 'problem', but it sure as hell cleaned up all the symptoms.

I have a long ride coming up and had been dreading it due to the wobble but the brace has cleared up any concerns I had.
