TTR90 Throttle sticking problem

Just cleaned carb and when put back together the throttle is hung wide open and the throttle cable will not return. Throttle body is aligned with the notch (now) and lubricated cable and checked for any kinks in cable. I've heard of other people having the same problem but no remedys. Any help would be appreciated.

I don't have the answer for sure , but I would check a few things.

the throttle tube and grip make sure the grip is not sticking to the throttle housing .

the throttle tube could be damaged or hanging on a uneven part of a possible damaged handle bar.

and check #23,5,17 on this diagram make sure it is all functioning properly .

I've seen the needle get jacked in the housing causing similar problems look for wear .

I monkied up #17 (throttle body) when I didn't know about the notch. I filed down any rough edges. I connected the throttle cable to carb without hooking carb up. The throttle body moves up and down with the needle staying in place. Is this normal??

No. the needle and #17 are one moving part held together by clips.
number 17 on the diagram is called a throttle valve according to yamaha I always call them a slide.

inside the slide is a plastic clip that affixes the metal clip (that is clipped to the needle)from the needle to the slide .

in other words on the needle there is a metal clip , it is used to adjust level of the needle the plastic keeper clip holds the needle to the slide (throttle valve or throttle body) as the throttle valve moves the needle moves
