"vibrating noise"

New 08 2600 miles. Great bike LOVE IT!!! Went to the TDP III last weekend and put her to the test!!!!and now I have noticed a Vibration noise at 3900 and 4000 rpms. It's driving me crazy I can't find it. Sounds like a loose license plate ratteling in a holder for a comparison.

It's comming from the front near the tank/shroud area. I have gotten a wrench /screwdriver on every nut/screw I can find. All seem to be tight. Is there anything under the tank That could be vibrating and causing the noise? Like a heat shield or something of that nature that would vibrate if loose and cause a humming/rattle????? Any suggestions?

Never pulled the tank before but it's the only thing I haven't checked(under it)

Pulling the tank on the 08' do I need to remove the shrouds or will she come out with them still mounted?

Thanks for any advice.

I recall several comments about loose muffler/exhaust bolts on new bikes.

What you describe does not sound like the "plastic buzz" that's common around the headlight fairing on the <07s.

Don't know about the 08, but the tank on the <07s isn't difficult but you do need to remove some plastic. Again not difficult, just a little time consuming. Everyone recommends draining the tank, but I personally don't drain it. Just be careful and use common sense - full tank can weigh 50lbs or so.

i had this exact same noise, but between 4-5k. it drove me crazy. i added some highway pegs (see my post) and in doing so the vibration went away.
unfortunately there are a few things that may have fixed it.
1. i did have to loosen and re-install the aftermarket skid plate, this may have been loose.
2. or its the highway pegs that took away some vibration somehow
3. it could also be your radiator guard, the flimsy wire thingy

Sunshine or thunder, a man will always wonder,
Where the fair wind blows.

The earlier models had a screw on the fairing that was too long and caused a vibrating noise. It was on the right side cover on the gas tank I think. Not sure about the 08's.

Today is the first day of the rest of your life.

Well after much to do I got it figured out!!!!!

Seems that the nerf bar where it mounts to the frame in the front of the bike was putting out some vibration. I notices a bit of wear marks on the paint. So I loosened up the two hex bolts holding the nerf bar to the main frame and got a piece of truck tire inner tube and forced it up between the frame and the mount. Then I torqed it back down...wala no more noise/vibration..she's back to normal.
HERES A FEW SHOTS.....

You can see the rubber inner tube sticking out from under the nerf bar mount




I would suggest to anyone mounting up the nerf bars to do this as part of the assembley..It'll save ya some headaches!!

Nerf bars.

Are nerf bars the best out there for the KLR? I need to totally protect my tanks as I've already laid the bike down soft twice. I know it will go over hard soon.
