Is there an online or mail order source for throttle cables? I need the one cable that emerges from the handlebars and goes to a device that connects it to two cables. Oops….I don't know where my brain was at when I wrote this. Actually two cables originate at the grip and go to the carbs and these are what I need. I checked Bob's and Max's parts diagrams and I can find the choke cable, but no throttle cables???
