You're assuming that dismantlers weren't just chopping these cables when removing parts from a chassis.

I bet a lot of them were, because throttle cables aren't a popular selling item.

Default Remanufactured AP1 throttle cable

So I managed to get my hands on an AP1 throttle cable that's been remanufactured here in Japan. It's intended for use on a RHD but I'm willing to give it a go as my 22-year-old cable is stretched to the limit. This one is 56.75 inches long, ~10 inches shorter than the OEM LHD one.








Here are the notes...translated from Japanese

It is a genuine Honda throttle wire that has been processed for the S2000 (AP1).
We have processed the wires of new Honda and other models so that they can be attached to the AP1 as they are.

The reason why I made this is that the throttle wire of the AP1 that we own is partially broken.
I tried to order the parts, but they were already out of print.
So I looked for a used one, but I don't know how much it was used, and the new one was traded for around 20,000 yen, so
I gave up and contacted a wire production company, but they didn't give me a very good answer, so I processed genuine parts and made it.

I thought it would help those who are in the same trouble, so I made several and exhibited them.


As for the processing part,
(1) The black resin part attached to the accelerator bracket (inside the chamber) is heat-processed into a straight line to fit the S2000.
(It can't be made completely straight, but it's processed so that it passes through the bulkhead without any problems.) )

(2) The drum on the accelerator side is made by cutting and processing brass rods.
(In order to increase the strength, brass pins are pressed in from the side to prevent the wire from falling out.) In addition, the head part is fixed by pouring solder. )

(3) The length is shortened according to the S2000 genuine wire.

(4) Since the two rubber points in the bonnet are in a different position from the fixing points of the S2000, the rubber of the caulking part can be moved by hand.

The above is processed. By the way, the stock wire diameter of S2000 is 1.5mm. The wire exhibited this time is 2mm size.

My own car is also used with the same process, and it can be used without any problems.

I discoverd that my AP1 does not have a adjustable Pedal Stop. E.g. some sort of bolt at the bottom of the footweell wich you can screw in and out to adjust the stop of the pedal. The S2000 has a Plastic stopper, but it´s not adjustable. Just a sort of wedge bolted toe the bottom of the footwell. Nr. 2 https://www.hondapartsnow.com/parts-...sis/pedal.html
With the Cable slack at the throttle valve adjusted according to the FSM (12 mm slack) the accelerator pedal is still several centimeters or 1 Inch away from the Plastic stopp in the Full throttle postion.
This means, all the pressure of your foot pulls at the cable and the the Throttle valve. This just seems not O.K. At every vehicle i had before, car or Motorcycle, there was a sort of mechanical stop.
Is there something wich i miss? Or is it really designed this way?

@Mr.Matchbox I talked to this earlier in this thread. Originally my pedal hit the plastic stop so not sure why yours doesnt. There is a black squishy bushing between the pedal and the cable end. Its there save the cable assy when you hit the throttle stop. Ideally you hit the throttle stop and the pedal stop with the squishy bushing partially engaged. I never liked how much slack you need in the cable to align all those bits though so i made my own adjustable pedal stop.

With the help of a little blob of bees wax i meassured about 10 millimeter play. Headed to the material store in my work and raided the garbage can. Found a pice of POM plastic. Bribed the guy at the table saw with a coffee.
Drilling, wrenching, chamfering with a file and i have a stop wich prevents me from over stretching the throttle cable in the the future.
I adjusted the throttle cable afterwards. There is not much slack in the cable, there is no play in the pedal, i hear the "Click" when the throttle valve open fully and there is about 1 mm left until the pedal finally hits the stop.
I call this O.K. And now the big question: Why is it so from the factory?
