Well, i went to see them yesterday and typically the box was working fine. A mechanic took it out for a spin and came back saying it was fine but perhaps the lever needed some adjustment, which he did and now things are much better.
Panic over
It's still not brilliant but i'm shifting up without bothering with the clutch most of the time now. When i get some time i will pull things apart and give them a good going over.
Will put this down to teething troubles.
