Throttle cable/distrib. box inspection

[kroberts]

I need some advice. It's about time for me to start putting my bike back together. While I have the tank off, the DME displaced, and have all that great access, I was thinking that I should look over the innards of the throttle cable distribution box. Is this a good idea or a bad one? Does it look like the insides of a Rolex?

What should one look for when inspecting the throttle cables?

Mine feel pretty good. No odd noises or binding. Throttles return with a snap and seem to operate very smoothly. I did notice that when the left TB bellcrank is against its mechanical stop there is a small gap at the right TB, maybe .050". I know that throttle sync is the important issue, I pointed this out as a FWIW sort of thing.

Should I just leave it alone? Does this require any sort of lubrication?

TIA

The Bowden box can be a bit intimidating to some. Go for it if you are handy and patient. Mine had some sand inside, I cleaned and lubed with graphite powder. Oil/grease will only attract and hold the dirt. Check your cable up at the throttle handle, that's where mine started to fray.

not difficult to do but not usually a problem either.

You could replace the throttle with the new improved version. Requires kit of parts at handgrip as well.

Never heard of this new improved version. Can you supply a link with more info?

They change the upper throttle cable at one point. that required a change to the handlebar assembly. You can see it on the MaxBMW fiche. Section 32, diagram 32-0965. You can't buy an old throttle cable any more, so you need all the new parts if you want to change your upper cable.

It's not a huge project. it might be a good idea to get it done if you're looking for something to do in the garage.

I replaced my cables at 50K. To tell you the truth, there was nothing wrong with the ones in there, I just thought it would be prudent. If I had to do over, I'd left them alone. The ordinal ones look pretty good. Just my 2 cents.

In some instances the original throttle configuration could see the cable wearing into the plastic. The new cable makes the 90 degree turn inside a metal tube that's part of the cable itself.
