throttle cables sort of sticking....

[irishluck]

So been awhile since I've been on here.

Working on my bike the other day ( 87 fj1200) and when I put the carbs back onto it, i hooked the throttle cables back up. both of them are connected been when I turn the throttle it kinda just gets stick there, like the other cable doesn't do its job and return the throttle back.

Any ideas? I haven't got a chance to sync my carbs back up and I'm thinking that might be why, maybe the springs or something arent strong enough to force it back down. I'm not quite sure...

They could need lubricating or they could be starting to fray.
Take them off and have a good spray with lube, and i'd go as far as taking the junction box apart, that box halfway down where the 2 sets of cables join, and checking inside and lubing with silicone grease or copperslip or something.

I did lube them up but didn't take the junction box apart and do it in there, that will be my next step. It just started to do this after I put the carbs back on after I rebuilt them again.

ill lube the box up and see what happens, no frays on the cable.

Be careful how you phrase things.

Thanks for the pictures, really helped out on what i need to do. One thing though, that little blue box on the first image, what is that? cause i dont have that on mine...

ha yea ill be careful about what i say about the lube ha

oh have another question, i cant seem to get any of my turn signals to work.... i have them all plugged in. the battery is charged as far as i know of, but i cant get them to work...

the head light works and so does the cluster console. and the front running lights turn on fine but other than that nothing...

Flasher plugged in and functional?

yea it is, i finally found out what it was, a wire was grounding out in the system.

Also i greased up the cables and no luck

1) Are the cables routed properly?

2) Did they always stick, or is this a new symptom?

3) If this is a new symptom, what did you change between the time the throttle worked.... and now?

And irish, you say you've done something to the carbs.
Did you take them completely apart, and not put enough tension back in the springs that control the butterfly valves?

Well see that's exactly what I think it is, I thought I had mentioned something up above about that but maybe not. I had completely disassembled the carbs, each one was apart. i was thinking i didn't tighten something tight enough or something. I also haven't had a chance to sync them back up yet. would syncing them have anything to do with it?

No. And you really won't be able to sync the carbs properly until you can get the throttle cables snapping shut as they should. You can get the carbs close to balanced on the bench but they won't be perfect.
