4-stroke sounds louder

[MajBach]

Hi all. I've had my Honda 90hp for 5 years now, about 400 + hours on it. I remember how quiet it seemed when I got it - especially compared to the 2-stroke I had. Lately however, it seems to be a little louder at idle. Am I getting used to it or is it actually getter noisier? Anything I can do about it?<br />Also, what's the idle level on this beast? Mine is currently about 950. I would like to turn it down a little ( trolls a little fast ). How do I do this?<br />Thanks,<br />MajBach
