diy "cruise" control (cable actuated throttle lock)

[skyl4rk]

I am very interested in how it works.

Sweet! never even knew this kind of thing existed. i used to use a tractor throttle on my old truck, but it was to bump my idle up for different reasons.

i'm going to look into this for the old truck when i get it running again, but i will hook it straight to the linkage at the carb.

I am interested in doing something like this, can you explain how you did the chain (I can not see it in the pic)?

I found two small cable clamps at the ace hardware.

I installed the cable so it pretty much pointed at the part of the gas pedal lever I wanted to pull on (the straighter the path, the better).

then figured out how long to make the chain by holding it up to the gap

then used the clamps to attach it to the pedal rod on one side of the chain and to the cable end on the other.

I could slide it a little bit on the cable end to fine tune it by loosening the clamp and repositioning it.

The key here is that the gas pedal actually pulls on the throttle cable via a lever, so I am clamped to that lever near where it connects to the throttle cable.

The chain just attaches to a clamp bolt at the ends, the pedal clamp goes around the pedal lever, the cable clamp goes around the cable. I think I may have flattened and even spot welded the chain ends to be captured by a clamp bolt, but not a requirement I'm sure.

Another way to do this:

Jeep Rubicon Express Hand Throttle Installation

The hand throttle kit goes for ~$30:

RE1000 - HAND THROTTLE - Rubicon Express

Parts might be cheaper at your local bike shop.

the one I installed had vernier control, so that ideally you could fine tune the throttle setting with ease by twisting the knob or make gross adjustments by holding the button in and moving it in our out.

I had a bit of fudge in my install though, so it took some finagling to make fine adjustments.

this looks very doable. I have had a hard time figuring how to do mine as it is an electronic throttle.
Did this help you?

[dcb]

Didn't really test it out, mostly an in-town driver and P&G everywhere. Was nice to have on the hiway though the few times I was on the hiway

[Weather Spotter]

would it be possible for you to take another pic of how the chain is set up?

[dcb]

Nope, it has moved on, wasn't very tricky, look at last pic closely.
