Friction noise was created by Fox

Hello,

After riding 30min and the engine is hot i can hear a friction from the engine.
Hard to tell where is from but i think perhaps a piston, a valve, valve guide...
if someone have an idea it will help me to seach the problem when i will look inside tonight.

You can hear the friction on the video... below the engine noise

Dry valve bucket? Spat a shim?
Does sound a rotational tapping noise to me.

Carbs need a sync
Controll valve lash
Controll and adjust cam chain tension
Controll cam chain guide and top idler, the old rubber damper parts can disintegrate and fatal failure!
