Hey all,

I've got about almost 1000 miles on my new K8 600. I've noticed a loud metal buzzing noise every time my bike gets up to 10k RPM. Doesn't matter which gear I am in. It starts at exactly 10k and then slowly gets quieter through 11K and then is gone once I past 12K RPM. It's really annoying, especially when I am excelerating through the gears. I've checked most of the visible parts to make sure nothing was loose. I know that these bikes tend to vibrate a bit from the engine, but this noise seems to be a little too loud to be normal. Anyone else have a similar issue or know what this could be?

Thanks guys,

Don't use under 12k:punk

Did u follow break-in? I don't think ur supposed to hit 11grand for the first 1000 miles...Just wondering......not sure how many people follow that anyway......lol

yea, I followed break-in. Under 8K for the first 600 miles. I haven't had the bike over 13k yet.

mine does it too. it is a combination of the clutch lever and the windshield. Haven't tried fixing it yet, but I plan to install a teflon shim between the clutch lever and the perch, and I will stuff some small rubber pieces betweeen the shield and the fairing.

interesting theory, ill be sure to tell my bike store to look at that first thing if i get the noise too once i hit that high rpm

Time to check out all those nuts&bolts. I had a similar experience on my DL-1000. At around 6500rpm, I had noise from around the engine and it would go away at higher RPM. Visual and finger feeling inspection did not reveal anything until I decided to re-tighten everything. An eye opener. Over a dozen bolts had to be tightened 1/4 - 1/2 turn and the worst one was the front fork bolts on the axle ... 1 1/2 turn. I was stunned that these fork bolts were so loose; could have had nasty results. The noise went away after this exercise.

It is not a defect or anything, it is simple physics. Every bike has a certain rpm where the bike kinda hits a natural frequency so to speak, and you can "feel the vibes". depending on the design of the bike, that vibration will be converted to noise you can hear. some bikes more, some less. THere is nothing that the dealer can do because unless you have something actually loose, they have no course of action. They will probably tell you that it is a natural characteristic of the bike which it seems to be.

Just got back from a ride today. I noticed that when I pulled in the clutch at 10k RPM, the buzzing immediately went away. I also spoke to some other gixxer riders who said they had the same thing happen. I think putting some more miles on the bike and finishing the break-in will help. Thanks for the responses.

another motoman breakin victim, 10k before broken in :wtf

RTFM!!! between 600-1000 miles you can take it up to 12K RPM.

Nice suit.

+1000

can try heavier end weights on the handle bars will help a fair bit

The 05-06 ZX-6R's did the same thing, higher RPMs and the clutch lever would vibrate so badly you would think the engine was having an issue. Most people who did not want to live with it inserted a thin plastic washer between the lever and pivot bolt - problem solved. Double check the GSXR by keeping pressure on the lever at 10K, if the sound stops problem solved.

I couldn't help myself this weekend, and took it to 10k before I should have, it definitely has the same buzz you talk about. Next time I am up that high I will do what MikeK06 suggested, and hold the lever to see if it goes away.

about 75% of the buzzing will go away if you hold the clutch lever. the rest is the windscreen converting the engine vibes to sound wave, kinda like a speaker.

I remember there used to be this model of VW that would start to shake apart above 50mph or something due to the mechanical resonance of a piece of it's underbelly matching the wind passing by it. I hadn't thought to apply the same idea to the bike. You're probably right.

My bike does the exact same thing. Right at 10k, gone at 11k. Glad that its not just me, lol.

it looks like this is normal from what i've been reading. hopefully the noise will begin to go away as more miles are put on the bike. if not, i'm going to have to try to find a way to dampen the 'vibes' so they don't produce any noticeable sounds. it starts to get really annoying! :cursing

just ride man.........ride!

Hey I wanted to share an observation that I made while riding today. The 10000 rpm noise also happens at 5000 rpm, although it is super quite. This makes sense because at 5000 rpm the "note" your engine is producing is the same as it is at 10000 rpm, just 1 octave lower. I bet it does it at 15000 as well, but we probably wont hear it over the motor screaming its sweet sweet song. Just thought that was a cool realization.

later..

cool.. thanks for the info. I'll listen for it tomorrow after I get my suspension setup!

also, the noise is difinitely the clutch lever. just put a thin plastic washer in between the lever and the perch and it is gone!!

So I rode 130 miles today. I did hear a very slight buzzing noise at 5K RPM like you said. I also found out that a majority of the noise at 10K RPM is coming from the ignition area and my key! While keeping my bike at a steady 10K RPM, I used my left hand to put pressure on my key and the ignition area. Doing so reduced the noise by about 50%. My key had a lot of vibration going through it! It seems to be a mix of different things causing the metal buzzing noise, but it's obviously is not a defect with the engine.

correct, it just so happens that this engine / chassis combo has some gnarly harmonics. I am over it, it is just part of the bike to me, and I love my GSXR!!!

I thought it was just me!...I have what sounds to be the exact same bloody problem, (drives me mad)..
My vibration/noise mostly likes to kick in particularly during throttle off and revving down between 14-10k...
At first i thought it was a rattling heatshield but after reading some threads on here, it seems it could be tons of things!!?
I bought my k6 from a Suzuki dealer with 1400miles so i've no idea if the dude ran it in properly or not...
Although it's not ready for a service yet i'm gonna bang it in (coz i'm goin crazy)...
If i get results i'll post em!

I see a lot of people saying its the windscreen or the clutch lever.. but i highly doubt it. I have the same problem with my bike at 10k and slightly at 5k. If some of you dont hear it, ride with a girl on the back and it will become insanely annoying and its hard to just ignore. Anyway about the noise. It sounds to me that its coming from the motor and feels like it too. This is why i say, even though its possible there might be some vibration from the screen and lever, that its all in the motor. REALLY annoying and so far the only thing i dont like about my k8 sixxer

the buzzing/vibration is coming from my right mirror. it's kinda weird. i would hear it, then i would hold the mirror, then it would stop.

hmmmmmm....maybe the hump on your back... =]

I a feature of the bike. It let's you know where you are in the RPM range mid corner without having to look down.

At 10k rpms it is my clutch lever. if I hold it lightly the noise goes away. at 5k rpms its my windshield, if hold that, it goes away. I tightened my windshield bolts and the 5k noise went away. Then I tightened my clutch lever bolt (had to replace the lever since the hit and run) and that 10k noise went away. I'm pretty happy now :punk. No more buzzing or rattling. Getting rid of those 2 noises really makes a huge difference to me for some reason.

There was also reports that the bolt that holds the plastic piece of the tank is making some rattling noises which could be fixed by placing a washer under the bolt. Give it a try if that stuff doesn't work. I plan on doing all 3 fixes.

yeah i know its an old thread.. The sound is from the ignition. If you hold the key firmly, or press it down, it will muffle the buzzing noise. Well, i decided to adjust the clutch and break levers to angle them lower and when i took the bike out, the buzzing was gone. The clutch must have been touching something for the ignition to vibrate. However, the buzzing at 5-6k is still there, but thats fine. Just thought for those of you who still have this noise might try this.
:dunno

Yeah, you also know the 5 to 6k buzz is the windscreen and/or front upper fairings right? PITA. never going away.
