2004 GS500F Engine Noise

[Skropi]

Guys, there is a slight misunderstanding in this thread... I am not the guy with the spark plug, that guys is the one who posted the original video. Please read the thread from the beginning  Oh, by the way, the video I posted has that sound that the op mentioned, but without that metallic tap  (and is the sound I have too and I believe its either a leak or cam end float).

So........nothing to worry about in my case?

Guys, I feel dumb now. I """"think"""" that the whistling noise I am talking about is from the air intake/air filter or something....... Could it be it? If I am right, how can we get rid of it? It is a bit annoying, to say the least.

Relax, it's just an air cooled DOHC top end, they are noisy. Especially the 80's tech GS engine. You'll get used to it.
Or use earplugs, that could save you some headache esp. with the wind noise at high speed. Don't need fancy plugs, just go to a pharmacy.
