Throttle question

My carbs are set up apparently for a push-pull throttle. But i only have one cable hooked up, thats the way its been since i bought it and best as i can tell function fine.....does it matter? What is the bonus of the pushpull set up? Is it necessary? Thanks!

Its a safety feature in case the return spring breaks or anything else causes the slides/plates to stick, allows you to twist back to idle. I'd hook it up.
 
Not sure if all GS bikes are this way but my VM carb 550 has pull-pull throttle cables but the BS/CV carb bike only has one cable.

Makes sense I suppose since the mechanical slide carbs have more friction thus the dual cable arrangement.
 
Hrmm...from the looks of the throttle housing on the handlebars there isnt a secondary entrance for another cable...I do know that these particular carbs were also used on many Kaws of the time, so maybe it was just a generic set up and they used pushpull. Or maybe my old 77 didnt use it and then went on later to use it. I do see in the manual that some of the setups on the later pre TSCC motors have a pushpull cable attached. Dunno.
 
It's not Push-Pull, it's Pull-Pull (pull open, pull closed).

I checked Bikebandit and it appears your bike came with the push/pull throttle so maybe it was changed out.
I've never seen a TSCC bike with a push/pull throttle unless it had aftermarket carbs.
 
huh...interesting...the equipment that is on it appears to be original 77 750B..whats the drawback of not having it?? It seems to function fine without.

This adds it up. With the CV/BS carbs the cable only actuates the throttle linkage and yours pulls up the slides and the linkage. If something sticks on yours which is more likely to happen than on a CV hold on tight!

True that i suppose. But thats what a kill switch is for...lol My step dads fuel injected Vulcan runs a push pull too...i have just never understood the concept of it. Guess i'll have to consider setting it back up.
 
The so called push/pull throttles on cv's simply pull the carb butterflies open & pull them shut when you roll on or off the throttle !

If you only run one cable i'd advise fitting a small spring to positively close the butterflies when you roll the throttle off, a common mod on chops & streetfighters over here to prevent the bike running on when the throttle is closed :)

Good advise. As Nessism states, they are pull/pull throttles on the VM carbs. It's a safety feature and also allows lighter return springs, provided the cables are lubed on a regular basis!! The correct routing of these cables ensures a lighter throttle feel as well!!
