Suzuki

Can pin point it but i think its coming from the cylinder head area or the clutch area i tryed putting a screw driver on different parts of the motor but im still not sure where its coming from when i pull the clutch when its in idle the noise is quieter when its enguaged its loud and when im on the move its loud and sometimes when i start it after its nice and warm it makes a single loud clunk/pop someone have any ideas thank you

Adjust the valves located in the front of the bike, or tighten the cam chain.
