Yamaha XT 600 engine "Rattle"...?

[petri oosthuizen]

My old XT has this "rattle", had this the past 10/12000km.
Doesn't really REALLY bother me, but ja, maybe fix it, why not??
Looks like a "stupid" thing and easy to fix.
Anyone done this?
And parts... @superfoxi Can we get, seeing you also have a 34L?
THANKS
