Slight knock . . . is it more of a rumble, squawk or a tapping noise? A rumble could be the bottom end bearings at the crankshaft.
If it's a squawk sound is probably clutch wear and a ticking sound from the top of the engine could be worn tappets/shims.
She's getting on a bit, any bike after 15 yrs is probably going to have the odd knock, it's one to ponder, as long as it doesn't get
any worse

Treat everything in life the way a dog would- if you can't eat it or foc it, forget it.
