Throttle peddle/cable connections ?

Hi All,

I need to make a decent connection between my throttle cable and the pedal bar.

I am using a pedal box that for the throttle, it gives a straight bar that sticks up into the engine bay, this bar swivels from below so just pivots forward and backwards like it needs to.
My throttle cable comes from the bike carbs and has a cut cable end that i need a locost way to fix it to the pedal.

What have others used, and is there a cheap kit for this, my temporary way to use a terminal strip isn't a great way to leave it lol

I've used somthing like this

on the pedal, I would then use a cycle cable end to stop it pulling through.

I was reading up on this recently. Lots of people mentioned using a 'choc-bloc' electrical connector (the same as a terminal strip?) to secure a loop as a their permanent solution. I guess there's not exactly a lot of force going through the accelerator cable.

Bicycle gear and brake cables usually just clamp with a grooved washer that bolts down to secure the cable, and I expect the forces are higher in that setup than for operating a carb?

Is it c.10mm round bar?

I’ve previously cut a pedal-bar like this down to an appropriate length, drilled and tapped for a small male rod end (M4/5 - can’t recall) and then used a clevis with a small hole for the cable with soldered end on pull and and screw down nipple the other side to stop it from even slopping about. Clevis is bolted to rod-end; rotates smoothly.

I've fitted a hard pedal stop so I can't break the cable end again after an overtaking embarrassment when with wide open throttle the solderless nipple let go and the engine dropped to idle. Ooops!

Yes I think it is.

So, I have drilled through the bar at the height it comes out of the bracket in front of it, and so far have just threaded it through and used a terminal strip piece to lock it off.

Am i right in thinking that i could now cut the bar just above the drilled hole, and then drill down into the top of the bar so that this new hole that is to be 'tapped' bottoms out at the cross drilled point, and then i could use a bolt to lock the cable to the pedal and maybe lock nut the bolt for good measure ?

Eek,

Thankfully the slot i cut in the foot well top for the pedal rod to pass up into is the exact travel of the cable originally bought, What a lucky first attempt I hope !!

That and the bike throttle bodies have full travel lock points so can't be over extended, I just need to make sure the tension is kept correct hopefully.

Sounds like it - but that sounds like it would cause the cable to flex at the end where it is clamped, and eventually snap. That was the main reason I knocked up a little clevis arrangement. If the limits of the travel were set I think a crimp end on the cable would allow a clevis to be used (assuming you can't just pop the clevis on the wire then put a blob of weld on the end to make it too big for the hole you've pulled it through...
