I picked up a 94 airhead GS a few weeks ago. It,s bone stock with 31,000miles. Everything works great but the throttle is stiff. I disconnected the return spring on the throttle cables and they worked smoothly with no resistance. I think that some weaker springs would be perfect but could not find anything at our local hardware. I know you can buy them for Del Orto but are they available for the Bings? Or does anyone have a source?
