Hey all! First post here... and I hope I'm just being paranoid! I recently purchased a 2002 LE Busa... black on black. 22k on the odo, 16 tooth front, Hindle 4-2-1 header through can, air box mod, BMC filter and PAIR mod. Bike dynoed well at 173.8 rwhp with a smooth power curve and great air-fuel ratio. All owners prior to myself were SUUUUPER old (40-50s 
) and it's my understanding they all did their part to maintain the bike properly. I'm sure the only time they went WOT was when they heard Metamucil was on sale at Walmart, so I'm not worried about prior abuse. 
The bike performs flawlessly throughout the revs, with the only noticeable quirk being the fairly common 5-6 false neutral, which has been solved by leaving my ballerina slippers at home when I ride. Still wearing the tutu, though. Changed the oil straight away when I got her home with Mobile 1 full synthetic 4t racing 10w 40 and a good ole Wix filter. The plugs gapped perfectly with no fouling/ corrosion to speak of, throttle body flaps were very crisp and clean, all vacuum and fuel lines appeared serviceable... bla bla bla. Everything looks in great shape. ANYWAYS, on to my point (sorry, I ramble!).
Though it's not easy to hear over the pipe, when I get down low and listen to the engine at idle, I can hear a constant noise... I would liken it to a small chain being dragged on the ground, and it follows idle speed, increasing in volume slightly with throttle. When revved, it "echoes" the exhaust note, falling behind by about a half second when you let off the gas and there's no difference when the clutch is pulled in. I'm just not sure if this is common with the Busa's or if it's the cam chain, or ??? This is my first big bore bike, and I've read that even healthy Busa's can be a little noisy. To be honest, I know more about the internals of Strykers and Humvee's than I do super sports!
Again, the bike runs perfectly. I'm hoping this will be diagnosed easily and y'all might have some troubleshooting methods... I've read these motors will break 100k with ease. Thanks in advance everyone! Here's a few pics of the Stealth
