Throttle woes

[RICKV.]

I just noticed that the push side of my throttle cable was broken inside the control. I was wondering if anyone cared to give me their opion on why there is a push/pull throttle system on my 1977 gs 750b? What purpose does it sereve? I used the search feature on this site, to discover some say that it is possible to just use the pull side of the throttle cable, as long as the spring is still strong enough to return the slides. Is there any down sides to this? Also I am having a hard time finding the push cable. I researched Parts Unlimited/ Dennis Kirk only to find that no part number exists for the push cable of my application.

Will anybody help me??
Thanks,
RICK V.

Replace the broken cable because having the throttle hang open when you don't have a closing cable can KILL you! Try Motion Pro or Terry Cables. Even a dealer can get you a factory cable. If no one will help you let me know & I will get you a part # & a supplier. Ray.

Hey Rick. Before someone else jumps you on the "push" part of the cable, it is really a pull-pull cable. As far as needing the pull-closed cable, no...you really don't. It is more of a safety issue and less of a function issue, though the nice thing about that type of cable is that when you roll back on the throttle, you know things are going to close. You can get by with the single cable. I've seen bikes where an extra "pull spring" was added in place of the second cable...to ensure that things closed tight when off the throttle. It is another option.

It's possible for the airflow into the engine to hold the butterfly valves open. Stronger return springs prevent this but can lead to really tough throttles and tired hands.
