Throttle sticks wide open..
Before anyone goes screaming "use search function" I already have.. Tried "stuck throttle, throttle stuck, sticky throttle, and just throttle alone" No findings.. on to my point if anyone can help..
Failed MD inspection for amongst other things the throttle sticking for a few seconds when held wide open.. I checked online for some resolutions and tried the easy fix first.. Picked up some cable lube with the little syringe thing and squirted some down.. At first it seemed to have helped.. a few hours later now however, it seems worse.. It won't click back to normal with out me helping it along.. Not sure what to do at this point.. I have a few weeks until my 30day temporary registration runs out and I'm not the most technically savy so I'm not sure I'm going to be the best at taking the whole tank off and getting to the carbs and all that stuff.. Thanks in advance guys..

Just some easy idea
- Check your grip and make sure its not rubbing on the bar ends or throttle cable housing
- pull your grip off and put some grease between the clip on and throttle tube, the throttle tube may be rubbing on the clip on.
I don't think it would be a problem in the carb, I think worst case scenario you might have to replace your throttle cable.

I think the above posts just about covered it. Mine used to stick and it was just the grip getting pinched between the bar end and throttle cable housing.
When I did my front end swap, I had too tight a bend in my throttle cables during one trial position, which resulted in the throttle sticking. I repositioned the throttle cables and everything was back to normal.
If it ends up being something other than what we already mentioned, I'd be curious what it was . . .

Here's another possibility, inside the throttle housing, make sure the cables or throttle tube aren't sticking in there.
The grip is usually the culprit. My friends 2008 CBR600RR wouldn't return to idle, I knew he had just changed grips. Slid them away from the bar ends, and all was as it should be.

Sweet.. thanks for the info! I did just put new grips on and I had to cut the ends for them to fit on. They're definitly not rubbing on either end. I pulled off the cable housing last night applied cable lube.. seemed to help for a moment or two then it went back to sticking only worse than before.. I'll check between the clip on and throttle tube.. Any recommendation on what sort of grease to use there?
Thanks again for all the input.. Pulling the tank off and getting into that whole area is not in my best interest with out having someone experienced help me along.. I fear I'd do more damage than good.. spill gas all over the garage, blow something up.. etc..

If that doesn't work, try taking the cables off if you can get a screwdriver in through the frame. Detach them from the grips and the carbs (again- I can't remember if one can do this while they're on the motor).
Then try to move the cables in the housing- if they move fine when not attached to the bike, it's in your grip, a kink in the line, or on your throttle at the carbs. If they don't move very well, squirt a bunch of WD-40 down the cables and move them up and down and repeat this a couple of times. I did this to mine and a bunch of grime came out. If you have a compressor, blow the WD-40 out but if not just let it drain as best as possible. Then put cable lube back in and hopefully that will work...
Just throwing out ideas...

Rt side fairing comes off, then if you follow the cables in they attach to a circular guide thing that rotates. THAT part is mounted to the carbs with two screws- if you take those two screws off, the whole things comes loose and you can pull your cables out. After that part is off it's pretty easy to pull them off the guide attached to your handlebars (which you also have to remove two screws to get to.
