Throttle cable stiction

[dnb]

I made myself a new throttle cable for the Griff using bits from Vehicle Wiring products. It's not straight forward, because it operates 2 separate throttle bodies on opposite sides of the engine bay.

It has a problem with stiction when opening the throttles. When the throttles are fully closed, and the pedal is pressed, everything is good - the pedal operation is smooth and the pedal feel is a little heavy, but OK. (It's about twice as heavy as my Impreza for very obvious reasons. )

However when the pedal is moved from 1/3 open to say 1/2 open it sticks and a lot of force is requiried to move it, and therefore the throttle overshoots. The cables are well oiled with thin oil.

On closing, the throttles do not ever stick open, and I can't feel the cables binding on anything.

All I can think to do is replace the outer sheath with nylon lined sheathing - will this really make enough of a difference?

All help is appreciated!

Nylon probably isn't the best stuff to use for a throttle cable liner. If you can get a teflon lined one it would be a lot better. Also (although you've probably got this already) the smallest amount of tension on the springs at the engine end that's possible to have. By all means have a spring on the pedal too though.
