Paul,
We used a peice of Nylaflow from just in front of the
pulley to just behind the forward rubbing block at the
front of the tunnel. The Nylaflow is attached at two
places;
1) with a cushioned P-clamp just in front of the pulley
2) at the approximate mid-point with the tufnol
guide block as specified by the Europa manual.
The front half of the Nylaflow is free to follow the up
and down motion of the cables as the pedals are moved.
In respect to the mid-point guide block, we moved it
around the general location specified until the fit minimized
bending of the Nylaflow/cable. You do want to get the
cable as far outboard as is practical to clear the gear,
etc.
