Back story: I had the bike ( 1970 Roadster with the centerstand on the frame) completely apart over the winter. Engine, gearbox, and cradle out. Installed new rubbers in the isolastics and a Dave Taylor headsteady with MkIII (?) style spring gizmo.
There is a noticeable amount of vibration up to 4000 rpm at least. Checked the clearence on the isolastics and it appears that the engine is leaning to the left. At the front, on the left, 0.010" at the bottom, tight on top. On the right 0.010" on the top, less than 0.005" at the bottom. Right rear is 0.005" at the bottom, 0.008" at the top. The ball end link in headsteady is loose when I'm sitting on the bike and tight when it is on the centerstand. Rear springs are set the same. There is no good way to quantify loose and tight with the DT headsteady link. And I have not checked the isolastics when I am sitting on the bike, but I suspect that they are tight at some point.
What do you think ? Grab the head and yank it to the right ? How can it be off ?
