Check the bearing to make sure/see if it rolls both ways (or one way) depending on which bearing you went with. Looks like it could be seized up.

Watched the video. The moveable sheave is getting stock on the one way bearing. You'll need to get in touch with whoever you purchased it from or could contact STM direct.

And to remove the STM primary just pull the primary bolt and use the same puller you used to remove your stock primary to remove the STM

To pull it try to water method. I believe there's some videos on YouTube explain it. I think you just put some Teflon on tape on the threads on the polar, Jack the driver side up a couple of feet off the ground so it's leaning, pour water in there, and then hit it with a puller. You act like a hydraulic polar that way

If you're doing the grease or water method be sure and put as much as possible in there. And put Teflon tape on the puller, it'll help hold the pressure. With the the hydraulics of the fluid will push it off.

Quick question. When you installed the clutches did you lap them per the instruction manual?

Don't know if this would work or not but I always took a rubber mallet and hit it at top, then sides, and bottom rotating back and forth then tighten a bit more then tap it with mallet and repeat. Always worked getting mine off. Had the exact same thing happen to mine when it had the one way sent it to Matt at STM and told him I wanted a two way installed now all is well.

yes..used the valve lapping compound!!! I have about 300 or so miles on the clutch...it happened when I was skirting around this mud hole then slid in so I mashed the gas pedal to get out and after that it was acting weird!!
do you think i could still use those pullers I bent??? or should I just wait for the new one???

I have yet to see instructions for an STM clutch. Where can they be found? thanks

I tighten my puller as tight as my cordless 1/2" drive impact will take it then I let the end of the puller have it with a 1 lb hammer a few times than burp it with the impact a bit more and hammer a bit more repeating this sometimes several times until it pops off. Works every time for me. Protect the face of your STM primary with something when you are doing this, it will scratch and dent very easily.

If you are using the Hydraulic method I don't think a bent puller will matter as long as the threads are still 100%

If you are doing the water or oil trick cut the bent tip off and do the hydraulic trick . Remember the Teflon tape , it will work , be carful with heat as you can wreck the bushing on the movable sheave
