Weird sound around 3,500 RPM

[bakirkwold]

I get this metal to metal sound around 3,500 RPM. Once it hits 4,000 its gone. Its like a chattering sound. Is this valve chatter?

Can you post a video?
Or does it just happen under a load going down the road?

Things that have caused rattles at various RPM ranges on my bike:

1. Loose exhaust shield
2. Loose front fender rivets (yes, even sitting still!)
3. Cam chain tensioner
4. Tach cable end came loose (slid down cable and was jiggling against the headlight ears)

When it was the cam chain tensioner, I could rev it and actually see the handle vibrating in the affected RPM ranges. Make sure you know what you're doing before you go playing around with the tensioner if that's it...

Things that have caused rattles/noises around 4K on my bikes.
Loose heat shield on the GS1100E. Actually thought it was a baffle in the exhaust. I replaced the heat shields, but there's one screw I can't get to underneath and forward and sometimes I still hear it on hard accelerations.
Loose header pipe on the GS1000E, just tightened and that went away.
Gas tank on my GS1000E, the rubber mount underneath the tank was missing when I got the bike. I later found it sitting on the top of the swing arm in front of the rear tire, oh this was after I ordered and replaced the missing one.
License plates on both bikes, sounded like a horn, just tightened them up.
Loose crossover on GS1000 exhaust, tightened up the clamp.
Hopefully yours will be easy to find and fix.

I will check that out. Looks like I need a new RR for the charging system. I will get that first.

I fixed it. It was the heat shield for my L pipe. Thanks guys!
