Replacing throttle cable

[Loukiii]

Ok for some odd reason my mechanic has fallen off the face of the earth and wont reply to my phonecalls and messages. So I guess I am going to have to embark on this endeavor myself. That was my original plan anyway but I guess I have been scared to actually do any work on the bike myself. Anyway...
Can I get a recommendation for a service manual? I know rpm has the parts. I am going to order it as soon as I get a service manual.
I have another shop in mind that could do the work if for some reason I chicken out again but think I want to tackle this myself.

To replace the upper pull throttle cable what all will I have to remove to get to it? Fairing? fuel tank? etc?

I will never twist the throttle wide open again... ugh...

You need to remove your fuel tank to get access to your throttle cables.
It is best to work with an empty or 1/4 full fuel tank
It's easy to do:
Remove:
1) Seat
2) Side panels
3) unplug tank drain hose (from fuel cap) from back of tank
4) unplug (2) plugs, the a) the plug on the wires to the tank fuel float (to your gas gauge) and b) the plug on the wires to your fuel petcock.
5) remove (2) 10mm bolts at rear of tank
6) lift up tank from the rear, reach in and disconnect the a) petcock fuel line (at petcock) and b) the petcock vacuum line (also at petcock)
7) Pull tank back and now up to remove tank.

You will now see your throttle cables. You will need a small Phillips or better yet a small JIS screw driver to remove the (3) screws on the cover of your cable slider box. Be careful removing these little bastards...if you drop one of these screws onto your engine, you will understand why I say this....(don't ask)
Disconnect your cable at the slider box....and at your throttle grip.....tape the new throttle cable to the end of your old one....pull the old cable out, your new cable should follow...

Cheers.   Pat

Thanks! I will give it a try.

That's the spirit! 

When in doubt....ask questions, we try and answer them promptly!

Not sure if it's just because mine is a 3CV model with the fuel pump, but i don't remove my tank completely for routine jobs such as the throttle cables Pat - i put a folded towel over the subframe rails and turn my tank surround once it's freed off from the grommets, and just sit it facing backwards on the towel/subframe. Saves the hassle of disconnecting everything and gives a secure place to store the tank.

Can you do this on the petcock models, or are the fuel lines too short ?

[Pat Conlon]

Hey Dean, yes, the fuel and vacuum lines are too short on the gravity bikes.

That's a shame !! ( it's been so long since I had my 1TX I just couldn't remember clearly).

a few questions.
The first picture shows a tube that comes out of the gas tank and is connected to nothing? Some type of overflow or air relief or something?

The second picture shows a tube that looks it was supposed to be connected to something but is/was not. What is it and where is it supposed to attach to?

The third pic shows a plug that is on the right side and was connected to nothing.. and I dont see anything nearby that looks like it should be connected to it.

The other 2 are just gratuitous "Look I took off my fuel tank" pictures

I am afraid it might have been too easy... so far.

[RPM - Robert]

One is the overflow. It does indeed go to nothing. If you overfill it there is a small hole and tube that will drain out of that hose.

Two is vacuum for the petcock.

Three is nothing it is extra switched power. Good to use for accessories.

[Loukiii]

Thanks that helps immensely

I knew this was going much too easily. So I made it more difficult for myself. lol

First pic is the remnants of the throttle cable.

Second pic is I guess called a retainer clip or something along that sort for the throttle cable. It is attached using a short screw. That would be the one I dropped into the engine.   

I dont suppose anybody knows the size I could get to replace it? 

[Loukiii]

Other than that lost screw lol it was pretty easy. Thanks for all the advise. I put it back together sans throttle retainer and it fired right up!

Feeling cute. Might try to synch the carbs next... need to find that screw though... or a replacement.

[Loukiii]

screw size is m5-.80x10 Or at least that appears to fit.
