So, the teflon liner cane out and wedged into the half moon cable housing at the throttle bodies on my K75S.
Have replaced the cable with a venhill replacement, sold through Motorworks. Seems the new cable is a bit longer, and I have about quarter of a turn in slack before the throttle now engages. No adjusters to be seen anywhere. Options as I see it,
1) Track down another cable; thought I had!!
2) fabricate an adjuster of some sort
3) Modify the cable:presumably I could cut and solder an appropriate cable end nipple to the exact size of the old cable.

What y'all think??

I'd add an adjuster at the throttle brace

Add an adjuster where the outer cable sits in the throttle quadrant (the half-moon bit) - I've done just that. You'll need to slot it to fit it over the inner. Don't even think of shortening and soldering as IIRC, Venhills are stainless steel inners.
