Still same problem.... no ides left

Post by Psycheonabike » Tue Mar 12, 2019 4:56 am



Ok guys....this one has got me stumped!!!

REALLY bumpy ride at slow speeds (under 20 MPH). Probably there at higher speeds but not as noticeable. Was there before new tyres were fitted and its there no matter which suspension settings I use including TRAC settings.

Symptoms are like riding over cobble road.

Checked:
  • Bearings
  • Forks (though its definitely coming from under seat)
  • New Avon Cobra tyres
  • Had Final Drive off and U-Joint is fine

Its there on the smoothest and flattest of road surfaces!!

The bumpi(ness) is NOT uniform so doesn't feel like a warped rim either.

What dya reckon?

You mentioned in another post that a lower rear shock mount was seized. Did you free it off?

Well apparently nothing is supposed to move there? Even more confused now. I can take a wheel brace to it but I suspect it would strip!

The shock should be able to pivot around the bottom bolt.
Also, have you checked that the swinging arm moves smoothly (disconnect both shocks to test).
