Question Throttle cables - push/pull, closing/opening?

I'm embarrassed to ask this question, but since Orleans isn't singing, I figured I'd ask some humans. I needed to replace the throttle cables on her, and bought replacements from Ron Ayers. The online fiche just has a diagram and listing for "cables," and says "this one's an opening one; this one's a closing one." ALAS - Clymer's and every other manual I've read describes throttle cables and "push" and "pull." I'm assuming the only difference in them is the length of the cable? Anyway, I've installed them - assuming the push closed, the pull opened - and I've got no spring-back in the throttle. My hands are freezing, so I thought I'd shoot a post to the group before I go do anything rash, but are my assumptions about push/close, pull/open correct? And if so, can someone give me a suggestion as to what I'm doing wrong? I'm pretty sure I've got the slack out of the cables, although seeing back to the push cable is hard (flashlight battery is cold and dying...it needs a break, too).

Yeppers, pull = open, push = close.

When I would have troubles like that, I would usually have something binding in the handlebar throttle housing.
Try detaching just one of them (where ever it is easiest to do it from) to figure out which cable is causing the trouble.

Thanks, Hyper, I'll try that...gotta be something deceptively simple, but there comes a point when it's hard to reason it out. "The entire assembly must be broken - sell the bike!"

Cindy -

Have had the same problem with mine, as a matter of fact just today. Like Hyper said, play around with the adjustment. You can remove the open cable pretty easily from the carb.

See if it springs back then. If so, you need to watch the adjustment of the two hex nuts that hold the cable to the carb linkage. Try moving it back and forth a little by loosening one and tightening the other.

If it still sticks with the open cable off, its the close cable. Hard to remove this one, but you can still change the adjustment and see if that frres it up.

Let us know.

Any idea, Jon, why your cables would suddenly start acting up? Just wondering (I know mine's an adjustment issue). I'll fiddle around with them this evening - it is nice to have new cables (the old ones had two washers inserted between the right-hand control piece and the cable bracket, just to give create "more room" for adjustment... )

Cindy,

To help you sort them out, the open cable is the one with the little cross bar on it that goes into the throttle grip on the handle bar. The close cable is the one that fits in the slot in the little cross bar. If you look at at the micro fiche, you can see what I am talking about. The open cable goes on the forward facing hole in the throttle grip on the handle bars and the close of course goes in the rear hole. On the carb, the open cable goes on the bottom connection on the carb and is the most accessable. The close cable goes in the top mount and its linkage is covered up by the open part of the throttle mechanism. It can be tricky to put in but it can be done with patience. I just had my apart and had to re route my cables as I had done it incorrectly when I put the bike back together. According to the Kaw manual, the cables run through the bracket above the radiator cap and then pass on the outside of the radiator hose and frame then down past the back of the right ear and over the spark plug and into the carbs.
Hope this helps some.

I disconnected the pull cable, and it was still binding. But I could hear it catching up on the mechanism up at the throttle. So I went to loosen that and check how the cables are seated, and - lo and behold - when the RH control piece is not properly seated on the bars (there's a small tab under the top half of the shell that sits in a tiny hole on the bars), I've got plenty of spring in the throttle. As soon as I seat the shell - binding. Now that presents just a small problem, since it'll be a drag to try to hold the throttle open and try to keep it on the bike at the same time - no cramp-busters for that on eBay!

I'm heading back out there....more anon.

If you can, disconnect the linkage from the twist grip and pull the cable as far as you can, then reconnect it to the grip and see what happens. The little tab on the top shell on mine broke off in the hole some time in the dim distant past so I haven't run into that problem. It may be that the lead end on the cable is rubbing against the shells once they are tightened. You may want to check the clearance there and maybe file them down if they are the cause of the binding.

It looks like the push cable is binding. I opened the shell, and then yanked on that cable every which way to see if it would cinch down against the unit, but it seems too long. When I open the throttle, that cable is popping up and then getting hung up in the shell. Someone want to check me on Ayers? 0053 is the push, 0052 is the pull?

Pull cable should be the shorter one and has the cable guide on it (piece that holds the cables up under the throttle grip).

Mine had a problem as I had the carbs off today (every Saturday lately). When I put them back on, I had twisted the two cables, so I had to take off the pull cable from the carb so I could untwist it

Going to re-sync them tomorrow.

Still have problem at WOT when it passes 5k rpm. Breaks up very bad and have to back off the throttle to get it smooth again. I can rev it to 6K and cruise there, as long as I don't go WOT. Very frustrating.
