Gah, throttle cable stuffed. Any ideas?

[k14]

Was fitting my spanky new quick turn throttle to CB today and after 4 or 5 turns (it was feeling schweet and smooooth) it got very tight. Pulled it apart quickly to find this. Now any ideas how to fix before Friday?

Most picture wire is of the same size and can be picked up in a long reel at the supermarket or even dairy.

I would then get a small nut and bolt the same diameter to the fitting in your picture and loop the wire around it.



...else your looking at a trip to the bike shop !

Look at the state of that filler cap. Really Kirk, you have to sand the chrome off & apply an etch primer if you want to paint over chrome.




. . . Mumbles something about plumbers solder melted in half a piston or whatever with some Duzzal flux & some brass replacement pieces & new wire. bike shop will have all bits.

It was like that when I bought it :2guns: not as if I would try to paint it myself. Whats the point of that, doesn't make it go any faster does it???

A likely story.:shifty:

[Kickaha]

Must be a MTB shop down there, they have all sorts of cable shit you can buy

[sidwyz]

Autostop can make push pull cables,
bit pricey though

[speedpro]

They still make Motor Torpedo Boats? I would have thought with the recession that the demand would have disappeared and they would have closed up shop.

Down here there is a big following, a shop on every corner...

Gee talk about cryptic callers. I have no idea how you go about throttle cable repairs? Are you suggesting I get some more cable (I actually have another CB cable that is stuffed at the other end) and solder them together? Does that provide enough flexibility at the throttle end of the cable?

Hi Kirk

I doubt that soldering two cables together will work - won't be strong enough.

How much adjustment is left - that is, how much spare cable?
If there is enough, you can cut off the bad bit and solder it back onto the round 'thingy'.
Before you cut the cable, heat the 'thingy' up and remove the old cable....
Put a bit of thick oil on the cable where you don't want the solder to run then
use liquid flux (HCL & Zinc) and a hot soldering iron to heat the cable end.
Once it is good and hot, tin the end of the good bit of the cable with solder.
Now cut off the bad bit of cable.
Fit the cable into the 'thingy' and resolder. :woohoo:

If there is not enough adjustment, then as Disc Dan says, find some picture wire and use that.

Fixing it at the other end is a bit easier. so use the other cable. Trim the inner cable, Shorten the outer cable a bit if you need. The slide on the top of the carb with the little rubber boot if it has one. to make a new end for the cable I use an electrical connector, crimp it on upside down not too tight and break off the end of the connector (spade, eye or wotever it is )check the length of the cable through the carb slide. When it's about the right length crimp the little stub left from the connector real tight then run a bit of solder over it. Works every time for me. :2thumbsup

Either of the above.
Back in the olden days that is how I fixed all cables since the bikes I rode were all obsolete and there were no spares anywhere...maybe that's why I had such a lot of cable problems...

Go to a bike shop with the old bits. Buy some inner & at least enough brass bits to make a couple of cables.

If you have a propane or other gas torch you can melt some solder (not plain electrical solder which is 60/40, try get some plumbers solder bar from M10 or engineering supply shop.

Feed wire through brass bit & splay end back on itself. dip in flux & then in molten solder (bit melted in small metal container in vice with torch on it). Make sure the solder flows nicely around it. Pull it out & let it cool. Do not knock or move it until it is solid, else start again.

If this all works then it might need a touch up on a grinder or file so it fits in to housing. Ok you're running. Now this is connected to a too long piece of wire which you thread into oiled outer. Cut roughly to size & thread on small brass bit that goes in carb. solder it on & try it out. It will be too long but you can say "the cable can be pulled out perhaps 30mm with the adjuster right in".

cut 25mm off (sharp linesman cutters) & put bit back on, splay out a bit, solder real well. Trim back & install/adjust.

cut 25mm off (sharp linesman cutters)

OR wrap a bit of tape around the bit you are going to cut and zip though the tape with a grinder.
The tape stops it spreading apart.
(I don't have sharp pliers)

Cycletreads use to do a universal throttle cable that you just needed to trim and solder the carb end for $10 go get one and fit it
all brand new not 30 years old
and hurry up and paint that f4 bike you have there

I just had to fix my throttle cable. Go check out my thread http://www.kiwibiker.co.nz/forums/showthread.php?t=103575

Was easy to do. Good luck!
