best new throttle cable pwk/plus 3 stem?

[dericsdad]

Getting close to time for us to get a new throttle cable... does anyone know the best place to get a cable just a little longer, that will work with our keihin PWK carb, thumb throttle, and plus 3 stem. The one i have is adjustible, and works, but is getting worn, and could be just a little longer.

Thanks, Dan.
