Old new rattle

[Cohiba54]

Ok you know how sometimes when doing a hard stop the oil in the engine sloshes around and you get a the rattle noise. Well I'm getting that noise when running up around 4-5k rpm. I wear a fullface and ear plugs but I did a quick run to the parts house around the corner and put on my half helmet, i'm not sure how long that's been going but there was the rattle. I figured I was low on oil but I'm at half sightglass so I'm good there.

Anyone have the same issue or have a mechanic buddy to ask? Let me know how yall fixed it.

Later!! and thanks in advance.

I had a rattle from when I first got the bike .
The dealer looked at the bike a few times and couldn't find it .
When I replaced the in tank fuel filter, I found the fuel filter contacting another part in the fuel tank, almost wore a hole in the filter case .
Since then, no more rattle .

I've never had nor heard of a rattle like you're describing. But I have heard of cam chain tensioners making a noise. Is your noise more pronounced on one side or another of the engine?
