..... yes I did
Anyways heres what I got and I learned alot from the search but I didn't quite get a answer that I thought fitted mine. But maybe I'm just paranoid and wanted some extra comfort.
I cant pinpoint its exact location but it sounds like a half tick half poof. Somewhat like a exhaust leak but not quite. its most prominent around 2500-4000 rpm after that I either don't hear it or it goes away. does it if its idle or in gear. I have heard some valve noise is usual and so is slide slap also something about airbox noise? I have a k&n air filter. I don't think its valves so much as its not a metal on metal sound really and its only really heard in that rpm range usually when I'm around 1/4 throttle. changes slightly with rpm but doesn't sound like a match. Any help? ill try to get an audio if it helps.
