I'd like to draw on the accumulated knowledge of the wise and mighty WERA bbs. A friend of mine recently resurrected my old 1986 zx600, it turned pretty nice, I think. The only problem is the old, clapped out stock suspension. Anybody out there know if there's any possibility of swapping out the rear shock for something off a newer bike? Maybe someone's got an old worn-out rebuildable shock on their shelf they'd like to sell? Appreciate any help, Thanks.
