Choke Cable adjustment v.I'm an idiot
« on: July 27, 2005, 03:37:48 PM »
Well I'm having a heck of a time trying to get my choke cable adjusted correctly.  I'm trying to keep it from slipping down when I have it pulled up all the way.  I also need to know how to set it correctly so that my bike will run when I start it but not rev up to 4k rpm when I'm stopped at a stoplight.  I've been riding around for the past week or so having to fiddle with the throttle stop and I need to put an end to this once and for all.  So if anybody can clue me in or point me in the direction of a good FAQ I will be very grateful.

I have everything at the top taken apart, I just don't know what nut does what and nothing seems to be getting any tighter.  I have a repair manual but there doesn't seem to be anything of value in there.  Anyway, thanks for any help you guys can provide.

When your bike is good and warm, set your idle screw(Throttle stop?) so that your engine idles at 1100 rpm (+/- 100) and leave it there. No more touching the idle screw :).

      The choke cable has an adjustment to help keep the choke lever from sliding down. Directly below your choke knob, but still above the bars, is a rubber cushion with a plastic nut underneath. Pinch this rubber cushion and tighten(clockwise) until there is sufficient drag to keep your choke knob from sliding down.

       When you activate the choke you are also causing the accelerator pump to add "extra" fuel to your mix. This helps the cold engine run until it warms up sufficiently. It will also increase rpms. If you get to a stop and your engine is racing try pushing the choke closed and see if that doesn't bring your rpms down.

        If you're still having trouble with the choke you can take the gas tank off and check where the cable attaches to the carbs. There is a little "pinch" bolt that holds the choke cable in place. If you don't have the cable "pinched" in the right spot your choke will not operate fully. Too much/ too little choke.

Hope this helps.
Give me..a frame to build a bike on, and my imagination will build upon that frame

Thanks for the reply.  Well I pulled another bonehead move when I broke the plastic nut when I kept trying to tighen it down.  Looks like this is going to need to be replaced now too.  >:(

Does anybody know where I can get a new one?  This is just getting worse and worse.  :-[

I found a choke cable with the part I need on ebay but it's for a 78.  That should work, right?

man, I feel like such a dumbass.  :P
