what are the condition of the tubes? could they have an ever so slight bend ?
seen this before,,we "clocked" the tubes and the sliders aligned with the axle perfectly...couldnt even see the bend until the tubes were rolled on a flat surface.
{ the only thing that could`ve caused this, according to the owner, was once when loading the bike, he rode it up a ramp onto the back of a pick-up and hit the bulkhead pretty hard. not enough to drop the bike, but mebbe just enough to bend the tubes!]
