Engine Rattle

[Lemongrab]

Loud rattle (almost a knock) from the engine at all engine speeds. Quieter at idle, louder on light throttle openings, almost disappears under larger throttle openings.
I'm guessing its timing chain related. Also noticed an oil leak but the bike won't have lost much more than 250ml.
Roughly 65k miles. Thoughts?

Definitely more of a knock or clatter than a rattle.
Sounds like its coming from the front sprocket cover.
When you touch that area, you can feel the knock.

Does it in drive and when stationary.

What is your idle speed set to?

Check the front sprocket nut

What is your idle speed set to?

Idle speed set to 1500rpm. Once the engine is hot it tends to idle at around 1800rpm

Did cross my mind, I'll take a look.

idle speed once warm shoulf be about 1250

I was gonna say check the sprocket, sprocket nut and chain, for wear. May even just be the rear wheel alignment out too?
But when you mention "stationary" do you mean completely still, or with the bike on the centre stand, bike in gear and the rear wheel moving?

What are the consequences of this to a carb'd engine? Running rich?

Stationary as in bike not moving, bike in neutral.

These particular bikes do run rich as standard anyway.
How long have you had the bike? (whatever it is, you need to put the year and model under your name to give us more info)
And do you know the history of the bike, in this example when was the air filter last changed? Changing to a K&N air filter can balance the fuel mixture a bit better by helping the engine breathe more.

If it does it in stationary mode then your best bet is to video the sound and let us hear it, for a quicker solution.
