clutch replacement

well im not sue the problem yet still gotta do a tear down to figure it out... clutch was slipping, unless under higher rpms, and slipped horidly at low rpms under throttle. no no clutch at all, i havent trid to give it gas in a high gear at a low speed but it felt like uit was fully engaged and it never felt like it was before unless i wasd in the uopper rpms.
any body got any hints???
also what if its the fork anybody know where i can get one????
i fear that may be what it is...
the way it was acting it would seem as though it would slip and not grip when it would have went but instead it just has no clutch i guess il have to wait and see
