throttle situation

so I've put up with this quite a while.. even after my bike's warmed up, I have to barely hold the throttle to keep the engine from stalling. My question therefore is wouldn't this be a throttle cable tension problem and not the carbs?? I hope all I have to do is maybe tighten the cable (can you do so and if so how?) and not thoroughly clean the carbs again lol. I feel this has to do with the cable and not the idle itself although I could be wrong since I have set the idle as good as I can after an 80 mile ride home from school and the next day the engine wants more gas again so I continuously need to barely hold the throttle at a stoplight

 

The cable should have a slight amount of slack. It sounds more like clogged pilot jets, or air passages.

Or you just need to adjust the idle.

 

you need some slack in the cable
holding some throttle does exactly the same thing as the idle knob except one pulls and one pushes
split the difference, i get 800/900 cold and 1000/1100 hot

 

There's a Knurl on the Throttle Cable at the end of the Swivel Bend at the Throttle Grip.

If the Bike's too hot to risk sticking your hand in to make an adjustment of the Idle Control Rod, ... the Cable Slack Adjuster can be tweaked ... a touch, to keep you from needing to Blip the Throttle to keep it from stalling.

A drop of Oil on the threads will let you turn the barrel of the Adjuster like a Micrometer.

 

well today's friday!! so I'm gonna take a look at it sometime this weekend either tonight or tomorrow. just wanted to throw this out there and see what others responses were. gonna tweek with the cable because i've adjusted the idle so many times and yes the spring holding the idle control rod has been cleaned smoothly.
hope some oil and the slack adjuster gets this minor detail squared away. Rick, I might be coming at ya if I don't locate it or still have questions thanks
