Hello

I have had my berg for a year soon. A couple of week ago I started to hear a strange sound.

I sounds like something vibrating on the exhaust, but I have checked all the springs.
The sound only appears when the gears are in, and the sound follows the engine and only appears on some rpm´s.
When I get off the bike and revs the engine, I can't hear it.

I thought it was the camchain, but I have a new chain and the sound is still there...

What do you think?

Edit: I forgot to mension that the sound only appears when the engine is hot...

I don't think that this is your problem but I had a similar tinkerling noise only when the bike was ridden, was driving me batty, I thought it was the pads rattling in the calliper, turned out to be the magnetic speedo sensor in the disc.

Don't know the year of your bike, but the 04 centre exhaust box comes very close to the crankcase near the cam chain tensioner, worth checking to make sure it isn't touching.

Thanks for the tips!

I have now glued the magnet in place and checked the clearance to the exhaust, but the sound is still there...

Any more advise?
 
The drive chain tends to rub on the frame and make noise. Check and see if there are any rub marks on the frame where the chain passes by it.
 
weren't the chain rollers found to be the problem for a couple of people?

if its a chirping noise at some rpms/loads it might be that one or both of your headers are bouncing around in the collector

I replaced the seemingly ok springs with 2 very strong 2 stroke pipe springs, noise fixed.

I put a welding glove on and felt the joins while riding, the header pipes bounced around a good 10mm at certain rpms/loads

the chain rubbing on the frame ripped my keeper link circlip out and casued a derailed chain. now I always put the clip on the side closest to the wheel.

orangeberg posted once that one noise can be the chain guide roller bearings
 
Al-*** the noise is back, sounds like a small tinkerling bell, defiantly the brake caliper, touch the front brake and the noise disappears.

I also have clattering-rubbinghttp://www.husaberg.org/modules/PNphpBB2/images/posticons/image_23.gif like noise starting at low-mid rev range when in 3-4-5-6 gears and the engine is under load I mean when I give some throttle.noise disappears when cutting gas or at steady speed without loading the engine.Also at WOT noise dissapears or I just can't hear it.
 
Grillbrit,
I've got an 04 FE550 and had a nosie that I picked up on when i got the bike it sounded little a light weight metallic rattle.

I took the advice of the guys onsite and checked the chain tension and found the chain at some point had rubbed inside the frame take the advice and make sure your chain clip is on the wheel side of the chain but the actual noise turned out to be the floating disc rattling like mad in the calliper.

It was more noticable at lower speed but when I stopped or touched the front brake the bike it went away..didn't take me long to find it and it was a really annoying sound.

I've decided I hate it so much I'm going back to a standard disc and throwing the floater over my shoulder problem solved....hoep this helps

Cheers

Thanks for all the answers!
It's pretty hard to explain a sound in words :)

I put my foot on the braake when riding but the sound did not dissaapear.

I don't think it's chain related, it does sound more hollow, but I will replace my chain soon and will put the clip on the inside.

I think the sound is more noticable on the left side in front of me, and it sure sounds like an exhaust rattle...

So I guess I will investigate more on my exhaust springs...
