CRF100F back tire clicking noise

Was riding on the trails with my 2004 CRf100F when i heard a weird clicking noise, almost a tinking noise coming from my bike when id hit some bumps, only occasionally. It sounded like it was coming from the front of my bike by the front tire. When i got home i inspected the bike, nothing was loose. Checked suspension which is fine. Then i turned the front wheel all the way to the right hard and i heard the sound again, now it sounds its coming from inside my back rim... or in the back brake. It isnt my chain or my spokes. If anyone has any ideas about the sound id appreciate it if youd share
