I have owned my Valk for 7 years now and have had Dunlops, Avons and now Metezlers, Progressive 412's and now 440's and I can't seem to get rid of a tire dance. Feels like a out of balance tire until I get on new blacktop and then 90% better. I have progressive springs with 10w oil in the forks. Seems the oil level was 7.25" or so. Any ideas?

Try the Dyna beads it will most likely take care of it.

Maybe you have a bent or out of round rim.

Your measurement is too low for fork oil. As I recall, the measurements were in the mid 5" range. Each fork being slightly different. |

What exactly does "dancing" mean to you? A more interpretive description may help us better trouble-shoot this for you. |

It feels like the wheel is hopping up and down. The fact that it gets better on super smooth road makes me think shocks/forks. Wheel balance or bent wheel would not change on smooth road. Right?

With the oil level in your forks being a couple of inches low, (you did measure from the top down, didn't you?), your forks don't have the capability to control the front end, neither compression nor rebound. Correct your oil level and test ride it. Also, Progressive makes a heavy duty version and if you're like me 200+ lbs, you probably need it.

Are the bars moving at all? |

I may be wrong about the fork oil level. It has been awhile since I did that. I guess I will check it out but it feels more like the problem is in the rear.

I have the same problem, (I thought it was the milage at 100,000 km) so I changed my u-joint, bearings and dampers. The shocks and bushings are in good shape (no slack) . I still have the same problem, (dancing on rough pavement) I have no idea what the problem is.

Have you checked for a tire trying to have a puppy?
In other words getting a bubble in the sidewall or in the face?
One of my Done Flops did that, and I finally found it in Montana, headed for Alaska. Added 3 days to my trip..

if ya have a bike jack raise the bike until it just clears the ground spin the tires looking for run out mark the center of the tire by standing a stubby on its rear as a pointer slowly spining the tire checking to see if it runs true or not

It can be difficult to distinguish rear end problems as they're more often considered a front end issue. If you sense it may be the rear check the rear tire AND even the torque value of the swingarm pivot bearing bolts.
I struggled for a few years not believing the swingarm bearings or torque could be the issue due to so little inherent movement in them.
After I replaced my swing bearings the ride is even tighter then new.
Just because you can't find any slop in the rear doesn't nesecsrily mean the bearings or torque isn't off enough to cause slight issues. Swing bearings can take quite awhile to worsen too and that's when it becomes dangerous.
To check the swing bearings, because I doubt any of us can exert enough force to detect movement if they're only lightly worn or under-torqued by hand, you need to use the weight of the bike.
With an observer watching the rear fender & wheel from behind sit on the bike [off sidestand/cntrstand & vertical] and rapidly turn the bars left and right to near steering lock. If the torque is light or the bearings are bad the fender will move over the stationary rear wheel.
