Quick update for anyone contemplating this job, in summary well worth while for cost involved.
Spent the morning tweeking the modulator/bowden cable until super smooth, kick down works as should too, under load and foot to the boards.
Just for info, on the orange type modulator the cover will provide fine adjustment within 360 degrees or slightly less, beyond that it needs to be removed.
Next on list, bushes and bearings.. and the odd joint..no, not that type of joint
, the ones holding LCA to wheel hub..
