Primary clutch help xp900

Out trail riding and driving it hard like always, but pullin back into where my trailer was it stalled out. Pulled the belt cover and found my primary stuck locked up.

One of the weights got stuck, used a tool snd hammer to free it. Started it up drove down the street full out. Got stuck again.

So my question is can these be rebuilt, anything that I should keep my eye open for during rebuild? Does anyone know what fails?

Thanks for help, sorry if this was answered it's hard to search on my phone.
