I have searched online and looked through previous posts on engine noises and came up with nothing. I've ridden around and put pressure on different areas like the fuel tank cover, windscreen, etc... and the rattle noise is still present.

This noise only occurs at 6100 rpm or there abouts. It is not gear or speed dependant just RPM. Anyother RPM and everything is fine. If I accelerate past that point rather quickly the noise is not present. Noise is only present when cruising and I hover around that RPM. I was just wondering if anyone here has experienced this. I'd like to try and figure it out and fix myself before having to take my bike to the dealer.

Last time I took my bike to the dealer, was to have my frame replaced due to damage from theft. After picking up my bike I started noticing all the small things they damaged. I complained but they denied it everything and blamed it on theft damage. They broke tabs on the fairings, bracket for clutch cable by the triple tree was never put back on, throttlecable broke a few days later, exhaust was not connected, etc... etc... So taking it to the dealership is a last resort, I'd rather just keep riding it around.

Any help would be appreciated.

Thanks.

That sounds like a dealer around here. Bad deal. Hopefully you get this resolved. Hard to offer any insight when you can't hear the noise first hand. Can you narrow down where about the rattle is a little?

Noise is heard from directly underneath when riding. unable to reproduce the noise when bike is stationary. I haven't tried it with the bike on stands, but I will be replacing my tires this weekend so I am going to try. I would have to say though that the noise seems more towards to right side than the left but hard to tell. I'll take a listen again when I ride again after it stops raining.

I thought about the timing chain tensioner. I am torn between a stock unit or an aftermarket one. I don't want to replace a part and it not fix the problem.

does the rattle occur on an opening throttle, closing throttle or steady throttle? if it's the CCT it will not happen when loading the engine.

Noise will occur at any engine load. It is RPM specific. Wether I am cruising, accelerating, decelarating as long as its that RPM it will make a noise. When I accelerate past it as I am getting up to speed, I do not hear the noise since I am revving past it rather quickly. I just took the bike out this weekend for a short ride from Washington DC to Annapolis, MD. It was all highway miles so I could test out different scenarios for the noise. Noise occurs at 6100 RPM load or no load as long as it's within that RPM range it will rattle.

I didn't think it was a chain tensioner. It almost sounds like some sort of exhaust rattle. I hope I can figure this thing out. Will anything detrimental happen if I run the bike on a stand? I want to see if I can put the bike in gear give it a load

I have figured out the noise. The catalyst in the stock exhaust manifold is rattling. I stopped by the dealer and they confirmed. Unfortunately I am out of warranty. Warranty was only good for 5 years or 30,000 miles and I am over both. So I am looking into replacing the whole exhaust with two brothers or yoshimura. What I would like to know is what other parts will I need to complete this, like a fuel management setup, CEL fixers for the exhaust valve, etc...

Thanks

dude this is slightly off the topic of your noise you are hearing, but my bracket for my clutch cable is broken too. have you found a repair for this? I've tried just about everything and nothing keeps the clutch cable from riding up in front of my gauges. it begins to ark as soon as i engage the clutch and i constantly have to feed it back down.

I ended up using zip ties. I actually used zip ties for fiber cables and tied them to the throttle cables in such a fashion that they stay put and so far I haven't had them crawl up and block the gauges. I'll try and take a pic and upload it
