Dual Cable Throttle

[sonny8l3]

Has any one used a dual cable (push/pull) throttle on a single carb VW? If so, how did you hook it up please? Any info will be greatly appreciated. Thanks for your time,

Yes.
Took the push cable out and did pull only.
Get a long go kart cable for cheap. Or get the good venhill cable kit.

At 1 point I was looking into something like this.
The founder of another Trike site made a suggestion that I look into how they do it on VW stile airplanes. I never did go through with it though

I'm not sure honestly, why you would want to run a push/pull cable?

 

[sonny8l3]

I had a couple HDs, more than a few years back, that had the stack push/pull throttles. It was a stock cruise control and I liked them a lot. Progress being what it is, the push/pull was phased out. Some times I think progress ain't worth a spit. My bars don't have room for the after market throttle controll that I am comfortable with. Also, I think it makes a cleaner look for the bars. Thanks for your time

Not sure what your asking, but the dual cable is not a push pull. Its a pull pull. It pulls it open and pulls it closed. Now the old Harley's had a push pull but the mechanism is in the bars. It had a solid inner wire.

 

[sonny8l3]

I've never seen a dual cable set up on any thing, but I hope that it will work the same. If I had the HD bars that had the push/pull I'd probably work on trying to get them on my trike. I can't figure why it wouldn't work the same, thus the reason for this request for info. on dual cable throttles. Thanks for your time

 

[Sidecarbill]

Well Sonny google internal throttle assembly I think its what your looking for.

 

[sonny8l3]

Thanks for the info., but, I am looking for info. on a dual cable set up on a VW motor. I have a '71 1600cc. My mechanic is really good, but he and his son own drag racer cars and not a motorcycle in the bunch. I figure any info. that I can gather added to his 44 years of specializing in VWs, we can probably put together some thing that will do what I want it to do at a price that fits my budget. Thanks for your time

Please don't take my $0.02 on your idea of adapting the throttle the wrong way sonny8l3:
After reading & thinking about your request for info on push/pull throttle control, I can't wrap my simple mind around why you'd want to install this on your VW powered trike?
As you are likely aware, VW only used one pull type throttle cable on their air cooled platforms. The factory single cable design worked well for 35+ years for them.
Without a full on redesign of the throttle circuit from front to rear, a dual system is not possible, financially feasible, or mechanically better in my opinion.
Assuming you are running a stock Solex carb. of some type, the amount of time, money, & sweat equity involved in going that route is simply not worth it.
It won't add value to the trike, nor will it perform any better as a result.
However, if you were to enter it in the show circuit, it might get noticed as a curiosity?
Bottom line:
Don't let my advice stop you, if this is what you really want to do...

So i don't know if this is what you are looking for or not
This is something like what I was shown when I wanted 2 throttle cables.
I wanted foot throttle and a hand throttle

Below is a very quick drawing of what I was told about.
Basically either of the 2 cables could pull the center section and pull the throttle
The other cable would just slide through the center section

I know not very good example but im trying to do this from memory of something I have have never seen

 

[DeathBySnuSnu]

So do I understand correctly?
Your not looking for true push pull, but for what we call dual cable these days.
Not something that would be mandatory for a VW.
But....
There are certain benefits.
A motorcycle has very light spring on the throttle return. Makes for an easy twisting throttle. As long as all the mechanicals are correctly functioning the "push" return cable does absolutely nothing, just along for the ride.
But....
With the light spring any binding of the cable, gummied up carb or any other kind of impediment of free movement and you have a run away stuck throttle. That is what the return cable is for, it now has a function, a load to pull and saves you from a run away throttle.
So.....
The number one benefit of a dual cable is the ability to run a light return spring with less wrist fatigue and still have a safety net to know the throttle can be closed.
A Hardley with the little tension knob between the cables had nothing to do with it being dual cable. It just puts drag on the grip not the cables or carb. The "push" cable is still slack and doing nothing waiting around in case it is needed.
So.....
Yes you definitely could run a dual cable.
Yes it would be sweet to have a light twist.
But sadly I doubt you will be able to go buy one.
If you want one badly enough then make it.
Just need the two groove wheel on the throttle shaft. Maybe adapt something from a bike. Or machine one from scratch by your own dimensions.

It would look a lot like this.

I am using multiple cables but for other reasons.

 

[sonny8l3]

The push/ pull, pull/pull, ect. is just semantics for my purpose. I kind of live in the sticks. Usually 20 miles one way to any place. I've had a lot of fun getting to this age and the effects are progessively becoming more evident. Holding the twist grip at a constant speed is getting more and more uncomfortable. I tryed relaxing the spring but the throttle would not shut down completely. I don't have the tools or skill to put in the internal throttle set up and my present bars would not accomidate it. Also, my budget doesn't have room for what it would cost. What I am shooting at is 2 cables attached to the throttle lever. Twist the grip one way and the carb opens up, twist the throttle the other way and the carb shuts down with no need for a spring.

No spring will maybe mean that the carb lever will stay at the point that the twist grip is turned loose.
I'm mechanically declined, so I hope that some one has tried or done this so I would not be left to my own design.
By the by, I appreciate all info and opinions. Also, I cannot be offended by what some one says to me or about me if they are not close enough to touch me. Especially if it is in reference to my mechanical prowess.
Thanks for your time.

How about this. Its a thumb throttle for an atv. Got it on ebay. Works with two fingers easy. My wrist was broken and I have a plate with screws in my hand so l went with this. Probly on there for 5 years or so now.

 

[sonny8l3]

Sidecarbill, does that work with a standard throttle cable ball or barrel end and attach to a 7/8 bar? A VW trike down here is pretty unusual and mine is unusual for the unusual. Your set up would fit well if it comes in black.

 

[Sidecarbill]

Thats a standard cable end. Its on 7/8 handlebars. Don't know what colors you can get. I don't know the ebay seller, its a long time ago. Just go on ebay. Look for thumb throttle 7/8 should bring up plenty. I actually think you could use a brake lever from a bicycle. Thats what I was gonna try but then I found this.

 

[DeathBySnuSnu]

Some good ideas there.

How about a foot throttle?

 

[sonny8l3]

The trike was set up to be able to swap over to a gas peddle, but very soon after I got it home the brakes went out. Had to replace every thing but the drums and 1 piece of brake line. The mechanic ordered a master cyclinder. It took some modification to fit it, now a gas peddle is not an option. I think a foot peddle would take away some of the scooter riding experiance any way. I sure did get a bunch of info and ideas. I think I'm gonna try the atv thumb throttle first. I'm gonna check to see if any of the stealerships stayed dry and are open. Right now a lot of places are closed due to the flood.
Thanks for your time

 

[sonny8l3]

Thanks y'all for all the info. I went with a vista-cruise one piece throttle lock. Quick, simple and cheap. I have some good ideas for the trike as it progresses to what ever it's going to turn out to be.
Thanks for your time

"push" - pull throttle cables.

to begin, there is no "pushing" going on ever, one cable pulls the throttle open and the second one pulls it closed in case something happens causing the throttle to not close. old dirt bikes had one cable and I blame one on a dislocated shoulder. the 2-cable system fixed that trouble. If you just have to use that system you will have to use a carb with the throttle wheel that excepts 2 cables, but the carbs used on vw motors are proven and reliable and use one cable. the return spring closes the throttle. If something happens that it won`t close you shut it off or hit the kill switch.
