Help needed replacing throttle cables

[Gliderjohn]

I did some searches both here and in general on the net and not finding what I need. I am trying to replace my throttle cables on my T-3 and have never done it before myself. The carb end is no problem but how do things work at the grip? There is a what appears to be a pin going all the way through about a half inch above where the cables enter the housing. Do I need to remove that. Do I try to take the housing apart in general? Would appreciate suggestions.

John, any chance of posting a picture of you throttle?  On all my bikes, and as you can see I have a variety, it's straight forward.  So happy to help but I just can't visualize your throttle from the description provided.  :BEER:

It sounds like you've got the OEM Tommaselli Daytona 2C (?) throttle, the same as on my T3. If so, that pin (a very thin spring steel wire clip) retains the rubber boot. No harm in removing it.

To replace the cables you need to remove the two  screws holding the chrome housing together and lift it away from the throttle spool (that is, the grip) that the cables attach to. Then you can see how to unhook the old ones and put your new ones in.

Hope this helps.

On the 2c that spring clip also holds the twisty end of the throttle cable sheath in place.  It's harder to keep the carbs synched if the clip isn't there, and it's hard to find a replacement when you lose it.  I'd recommend keeping it safe.

If you have the plastic throttle, the wire thing flips up, rotating to drop the plastic cable retainer. You can then look up to see the barrel holders that are on the twistgrip as to slide them out.

Now that you mention it it is the Daytona 2C. Thanks for the procedure and to the response of others. I will try it out.

John,

Most of those early throttles the cables will just drop out for you.

Undo the spring clip and remove the plastic cable holder. Rotate the throttle to fully off and see if t will rotate a bit more. The cables should just drop out with a jiggle.

Replacing is the reverse. Probably no need to touch a screwdriver.

Another question. I removed the broken throttle cable. Now, to put the new one on do I have to slide the new cable out of it's rubber sheath, thread the small carb end through the metal adjustment housing at the grip and then thread it back through the sheath? I don't see any other way to get it through there.

I just did this so...

Start at the carb and get the cable/spring/slide all together with the cap of the carb screwed down.  Did you remember the rubber dust cap on the cable sheath?  If not do it all again.

Ready now?  put the adjuster screw on the carb top all the way down, you will need the slack.  Route your cable up to the handlebar and lube it while you have the chance.

With the throttle on the handlebar take the top cap off the Tommaselli to reveal the black plastic drum.  Since your cable is now all slimey with lube you can force it up through the rubber boot It WILL fit.

Now slide the cable end sideways onto the drum and roll the drum back.  The cable is now lying on top of the throttle lined up with the slot.  Pull the cable down until the slide hits the top of the carb and fit the cable through the slot.  It will snap into place and you can slide the rubber boot into place.

Mine did not have a wire or even holes as seen in this fuzzy picture:

guzziownr, thanks for your help but your set up looks different. My set up has two separate cables. The picture here is of the second cable that I have not yet undone. The metal housing pictured with the adjusting nut is where I am stuck on how to proceed. The only way I can see to get the cable through there is by sliding the new cable out of it's rubber sheath and threading the small carb end through that housing and then back through the sheath. Am I on the right thought track?

Something isn't right there.  I don't think there are two holes in the cable end retainer area on a 2c.  The cables should be retained by a spring clip that simply snaps into the holes in the throttle housing and then in a groove in the cable end.  If there is a pin holding the cable in place instead of the spring clip (that detail is conveniently out of focus) it's because someone lost the clip and made do with a roll pin or nail or something like that.  The pin needs to come out.

Also -- Are you just replacing the stranded cable inside the sheath, or are you replacing the entire assembly?  It reads like you're trying to get the cable through the sheath.  If that's the case you're also going to need to solder a new barrel on the cable end/set up the free length, etc.  Unless you do this all the time it's a PITA and difficult to get right -- wrong solder or technique will make a bad/brittle/loose joint that fails with use.  I'd go with the total replacement assembly for convenience and safety.

I have new cables I bought through a dealer.

 ;-T  That's the good way to go when you can.

So is there some sort of roll pin/keeper in that extra hole (in your pic) holding the cable in?

 . . . and I need some of the cable angle end bits to build a cable for a lid release (need to make two hard bends).  Will you have extras when the job is done?

Do you mean like the ones that go on top of these carbs?  If so I have two for you.

[rodekyll]

That's how many I need! 

Do they have those carbs attached?   :drool

I've converted a loop tank into a glove box/fuse box for the trike, and I'm using the filler handle as a lid latch trigger.  The lid hinges at the front, so a cable has to snake around the inside to the jackal seat latch fotoguzzi sent me for in the rear.  I need to do a right-angle turn at both ends of the cable to get it routed stress-free.  I'll be using s/s stranded cable inside a Teflon-lined sheath, and the sheath doesn't like to bend that tight.

[Gliderjohn]

Thanks for everyones help. Let me sleep on it and with everyones notes I will take a good look and fiddle with it tomorrow evening hopefully. Sometimes I am a bit thick about these things. And yes I do have the round carb setup that was pictured, but it is at the throttle end that I am not making sense out of it yet.

From your description you already have a set of cables made up.  From your question I gather that they do not have the angled fittings on the throttle end.  Is this correct?

If so, it is not the end of the world.   Just remove the angle fittings from the throttle assy.  You won't use them.  The ferrules on the ends of your new cables should fit up into the throttle assy.
