I've got a case of the hands-off shimmies, too!

It just started in the last few weeks.

Wheels are aligned fine, tire pressure at spec.

It doesn't seem to matter what speed I am going, but it always when decelerating, whether it be 90mph or 20mph.
(I can't say I have the same problem when accellerating with both of my hands off the bars as I haven't found a good way to do this yet, lol.)

I'm 250lbs and it seems to be worse when I stand up on the footpegs with no hands, or sit up on the tank (showing off.)

My back tire is showing cords, the front one is starting to entirely lose its tread. So I'm not going to worry about the shimmies or fixing them until the tires are replaced this week.
