Loud engine tap sound

Hi all,

Started my '96 Cbr900rr today and it started to tick. I turned the choke off and it started to die so I turned it back on, but as soon as I did it died. It had trouble turning back on and when it did it made this loud tapping noise. I'll link a video I took of it because from all the ticking videos I've seen this bike seems to be the loudest The bikes had a fresh oil and filter change, new spark plugs and the previous owner had a valve clearance done.

Note: I am not in any way knowledgeable when it comes to engines and such.

If anyone could help that would be great.

Edit: cylinder 3 is not working properly. I fired it up and the other cylinders are hot but 3 is not. A few days ago I ran seafoam through the tank to try and clean the float bowls. Hopefully this helps.

Re: Loud engine tap sound

Okay so the problem was the spark plug came loose. I don't know how, but it was. I'm glad that's all the problem was.
