Throttle cable question

#1

Post by 48Doc »

On my way to work Friday morning, after shifting into forth and twisting the throttle, the wire broke at 65mph going into a turn. Exciting to say the least, I shut her down immediately, and avoided a potential disaster. My question is as follows; Should I modify my stock 48 FL cable routing? The wire broke about 4 inches from the carb. There was about 15k on this wire, should I just change out the wire every 10k as routine maintenance? I don't find anything in the manual on this. Interested in your thoughts. Thanks in advance!

With 15k on present routing placement, why change. The wire just fatigued out, DooDoo happens.
I bet that was interesting, if you where in a turn.

If your bike is all stock, I would not change the routing. If the outer coil is in good shape, just replace the inner. And add "lubricate control coils" to your periodic maintenance chart. In fact, if you check that chart in your Service Manual, you might find its already there.

I don't know what you do as far as maintainence, but I like to pull the core out once a year and grease everything. I don't think that gauge wire should break at all , I know the 48's have that bend in the routing, where it was changed the following years ,
But even so that's a pretty heavy gauge wire

It broke at the bend, and was well lubricated. Metal fatigue, secondary to the stock routing? I'll add it to the annual preseason check list. Thanks for the input.

Hi Doc,

I'm running a 48 with a Bendix carb, single cable. The carb uses a screw stop that I tension on the cable with a flat tip screw. PROBLEM is, I have to cut the little nubs off of the end of modern cables. What I do now is silver solder the cable for the first 1".

What the heck, where was I going with that? Sorry, what I use is bicycle cables. They're tougher, and about $4.00 apiece, I carry 2 spares zip tied under the seat. Cable fatigue for sure. Cables specifically for mountain endurance bikes are made for a lot of abuse. Look for those.
