Tightness in throttle cables.

[PhredValk]

Hi gang. I have an unusual situation with the throttle on my 99 IS. After installing my air box (again) the ring clamp thingy got stuck at the top of the tube over no. 2 carb (right side front). Not wanting to pull the air box (yet again) I spent a half hour poking and tugging with various implements (screw driver, pliers etc) and I finally got it into place and all seemed well.
After installing the gas tank everything seemed OK until the test drive around the block. There's a resistance in the throttle that feels like tight cables. Not a pull, as it overrides the return spring (I have to pull the throttle grip to go, and have to 'push' it to throttle down).
My question is this; did I misaligne the cable runs, which might cause the cables to rub, or would accidentally over tightening the cables cause this (I may have 'spun' one or both adjustment wheels, I was working blind in a tight space)?
I really don't want to pull the air box again, but am setting out on a 5K mile vacation in two weeks and don't want to be worried about cables snapping part way.
Thanks in advance,
Fred.

Not sure what you mean about spinning the adjustment wheels? Did you have the carb ends of the cables out of their brackets? If not, sounds like a twisted or bound cable which may be caused by wrong routing ( did you have them out of the bike?). Are your risers and other components stock?

Start by loosening both nuts at the switch housing ... Just enough to let the cables fall where they want to. Operate the throttle and see if that does anything. If not, your answers to the questions will dictate the next step(s). It is difficult (but not impossible) to adjust the carb ends with the box on.

Thanks for replying.
I never touched the cables or carbs intentionally, just fidgeted with the airbox clamp in an area around where the cables enter the carb bank. I'm thinking that I may have inadvertently spun one or both adjustment wheels (spinners on the ends of the cables for fine tuning). I don't know what this may have done. I may have moved or twisted the cable entry points, causing a kink or bend in the actual cables, making a cable break possible. I just don't know enough about this area to know what I may have done, and it's very hard to see from outside the tank and airbox.
I'm hoping that someone with more complete knowledge of this area may have historic experience with this kind of thing and could tell me what could have caused this 'tightness' in the throttle.

you said you just installed the airbox which means you had it out. if that's the case.
iv'e had this happen to me a couple of times. your going to have to remove the airbox and resituate those cables. don't know how it happens sometimes but the cables get kinked by the front of the airbox .

make sure the double nut adjustment is installed in the right place on the carb/throttle frame. the nuts both ends of the cables esp at the throttle tighten or loosen the slack in the cables. too loose and too much movement/play in the throttle, too tight and u can have the now return/hard to use throttle u have.

3W-lonerider nailed it. The lower of the two throttle cables ended up on the wrong side of the airbox tube, going around the tube and under the airbox, which not only kinked it, but made it tighter than it should be. Pulled the airbox, cable-tied the cables to the frame (loosely) and reinstalled the box. All is well.
