Choke install

[jamman18]

I have a 77 750 and recently removed the choke cable because it was stuck down and closed. Cleaned it all up and replaced it but not sure I got it in there correctly because it feels like it pulls up too far or something. The bike starts briefly at a very low rpm and then stops like it's not getting enough gas. I try to adjust the choke as I'm  starting it but it never seems to be quite right. Is an improperly installed choke a possible cause of my problem and does anyone have any video links on installing a choke cable or advise for doing it correctly?  Thanks!

Just hook the end of the cable on the choke lever on the carb, push the knob all the way down, then tighten the clip that holds the cable housing at the carb. Done.

Found this on the web......any adjustments I need to make with the nuts in the drawing?

Sorry, I'll try this quality

Mine looks like this one

One problem I see after taking things back apart is that the end piece that hooks onto the carbs is at an angle and won't lay straight in its holder. The other problem I saw is that the carb end of the cable was not right into the holder. It had a lot of slack. Not sure I see how to take up the slack though. Doesn't seem to be any adjuster.

Those drawings are of the throttle cables, not the choke cable. Which cable are you working on? The choke cable is the one that is held to the carb with a pinch type holder that goes over the cable outer sheath, and is adjustable by where you have the cable set when you tighten it down.

Sorry......wrong drawing.  Choke cable for sure. I see the pinch type holder for the sheath which is tightened down via a Phillips screw. Then the actual cable comes out of the end of the sheath and then sets in between 2 metal little forks. But the nub at the end of the cable is turned at an angle and won't sit straight. Plus the cable is loose enough to where the nub is not even sitting in between the forks where it should be. How is the slack taken up?  Or do I maybe have the cable routed incorrectly. I may have to try to take a picture.

Pull the sheath up until the slack is out of the cable, but not pulling the choke on, then tighten the pinch doohickey down. It does not matter if the barrel on the end of the cable is not seating perfectly, it will still pull the choke closed when you pull the knob out.

I have never had slack matter on a choke cable. Take off your airbox. Now, hook the nub into the choke arm, The pinch with USUALLY grab the metal at the end of the cable sheath. I say usually as I have a cable that is apparently a bit shorter than oem and I pinch on the sheath itself, but not tightly. From there, route your cable to the bars and mount. That should be all there is too it. The flaps should be wide open when the choke is not pulled. When you do pull it, they should close virtually all the way.

Thanks for the tip!  Got all the slack out and the choke lever doesn't pull out as far now. Bike fired up but was putting out a lot of light colored smoke. Any thoughts on what that might be from?

[TOOLS1]

Did it stop after it warmed up? How long had the bike sat since last running? Did you crank it a lot while trying to work on the choke cable?
TOOLS

[jamman18]

It stopped basically when I stopped throttling it. It hasn't run in about 9 months and I did crank it a lot when working on the cable.

[Re-run]

I would guess the fast idle cam on the carbs is not set right. It bumps the rpms up while the choke is on.
You can temporarily turn the idle knob to compensate if you don't want to hold the throttle.

What color was the smoke?

[jamman18]

Definitely not black......it was a light color. Either white or very light blue......not sure. Sure stunk though

[jamman18]

What do you think about the smoke?

[TOOLS1]

Probably just oil that had seeped past the valve guides while sitting. Since it stopped I would not worry about it.
TOOLS

[jamman18]

Sorry, I didn't realize I had said it stopped. I actually was speaking of the motor stopping. Definitely smoke has not stopped. Also, same gas that I've had in the tank without stabilizer. Thought I should change that. In addition, I had a friend tell me he got some system cleaner that you add to gas from oreillys that cleans all the Crap out of your carbs. He ran it through his and then took apart the carbs to check them and they were clean as a whistle. Think he called it XP cleaner or something.

Got the seafoam and high octane gas in the bike after draining the tank. Now I'll wait over night before firing it up to let the seafoam do some work.

[Re-run]

The high octane fuel is useless. All high octane does is resist detonation. The actual energy content between regular and premium is the same. You can actually cause your bike to not run as well. Weaker ignition systems, such as those with points, do not properly burn premium and that incomplete burn turns into carbon.

At least the seafoam is in, and that should help with fuel burn.
