looking for a good source for throttle cable, is the stuff they use on push bikes anygood?

if your using a pinto nas yr avatar says,the std seirra cable fits a treat,just need ball from seirra pedal welded onto mk pedal

eh!

I've used a bike stainless steel brake cable from a local cycle store. Very cheap, about 2 pounds all in plus 1 pound for a second inner in case first breaks.
Never needed 2nd as first is still OK.
just make sure you use a swivel at both ends and it has no chafing points.
Teflon lined outer sheaths are also available but cost about 5 pounds.

Rob do you have any pictures of this setup?
