Rattling Noise and Vibration on 919

Hey all, this is officially my first post about my "new to me" 919. I've had it for three months so far and have been dealing with a very annoying rattling noise. It is to the point where I am grinding my teeth every time it happens, and it is embarrassing to ride by people because I know they can hear it.
Anyways, here are the details.

It occurs between 4k-5k rpm, with a peak at 4.5k, which happens to be my preferred cruising range.
It sounds almost like plastic on metal and is high pitched.
I tried taping and dampening any vibrations in the headlight bucket to no avail, but I am not ruling that out yet.
I also took off the plastic radiator grill, but no luck there either.
It only seems to happen at speed so I cannot pinpoint it in the garage.
I can only hear it in first and second gear, but that is probably because of wind and road noise at higher speeds.
I believe the noise is coming from the front of the bike but I could be wrong about that.

So, if anyone could offer up suggestions of common noise issues and places to look,or has any experience with this issue, it would be much appreciated. I already searched a few topics here and will begin my hunt for this funky vibration tonight.

Welcome aboard.
Does the bike have the OEM flyscreen on it? Mine had a similar vibration and it turned out to be the factory flyscreen

It did have the flyscreen, but I am running it naked. Oddly enough, I never noticed the noise during the first two weeks that I still had the flyscreen on.

Also check the exhaust stock heat shields (if stock is on there). If they are not tight, you will have that rattle from vibration

Do you have givi crash bars on your 919? 4-5k rpm is the exact range the metal joint in front starts to rattle unless you use silicone or something else to fill in the space.

No Givi crash bars, but I will check the exhaust heat shields later today.

One of the white plastic tabs that attach the gauge cluster to the upper triple on mine broke and it took me eons to figure out. Sounds similar to what you are describing.

It might be worth while to take another look at the connectors and wires in the headlight bucket. I had to go in there twice to finally kill the vibes in there. My buzzing was at 5,200-5,500 I believe.

Did anyone think to suggest that he's just referring to the normal vibration in the 919 that occurs between 4 and 5K rpm's?

Try the Clutch lever or your keys

I may not have a lot to say but it doesn't mean I don't listen.

At the end of last riding season I had a vibration noise at 4k to5k rpm. After winter storage it came back until the right exhaust shield fell off. The fastening nut on the exhaust pipe was fractured and completely separated. By the time I retrieved the shield from the side of the road it had been ran over and folded in half.

There are two rubber bushings for the rear mounting points, one of mine is missing. This may have been the source of the noise (vibration) on my bike which allowed the mounting bracket to fracture. Its worth a look.

Update: It seems that the "typical 919" vibrations around this rpm range are exactly what is causing certain components to produce the high pitched buzz. But I can definitely tell that this is not just a normal vibration.
Anyways, I taped up the wiring in the headlight bucket and put a line of tape around the inside of the chrome headlight ring. I also pulled of the gauge cluster and confirmed that the white mounting tabs are all still in good shape.
Towards the back of the bike, I noticed I was missing a tail light mounting screw, so that was replaced. It was then that I noticed the seat lock assembly was vibrating like crazy while reving the bike. Even though the assembly was tightened in place, the locking pin would still buzz. I secured it a bit with tape to prop it in place.
So after putting everything back together, there is still a buzz from the front end while riding... I really thought I had it solved with the seat lock haha

I still think it is coming from somewhere inside the headlight bucket even though I just tried securing everything in there.

I have a rattle coming from the instrument cluster at the same RPM range. When it's safe to do so take your clutch hand and push down slightly on the cluster in 2nd gear at 4.5K, mine shuts up when I apply pressure to the cluster. I just haven't had the time to take it a part and see whats going on in there.

One more thing: Perhaps the radiator guard is vibrating. I know mine sits slightly loose

lol sounds about exactly what i did... also removed the chrome ring around the glass of the headlight and put a bead of clear silicone... as well as putting dobs of silicone where the rad guard touches the rad.... still same vibes.

+1 on the clutch lever area. I was chasing a rattle for a week. Even rode with my helmet off around the block like an idiot trying to locate it. Squatted down revving the motor and listening too. It ended up being the locking collar for the clutch cable adjustment. It threw the sound like a ventriloquist!

Also, check your mirrors. I have the round OEM ones, and the internal connection on the left is a little loose and can give a weird sound in the rpm range you mentioned. Pinching the mirror with your left hand at rpm should tell ya if it is or isnt. Good luck.

Today's work order... Remove headlight bucket completely and do a lap around the neighborhood to see if the noise persists.
Next would be removing the gauge cluster and doing another lap. Now if I unplug both wires from the gauge cluster, will the onboard clock be the only thing affected? I don't want to mess with the odometer haha

Odometer will remain intact. I don't know about your trip meters but I doubt it.

Oh and noise? What noise?

So I took a quick ride before I started pulling everything off and much to my surprise, the noise was gone. It seems like the seat lock bracket may have been the sole source of the noise. I'll give it a few more days before I assume its fixed for good. As far as other possible sources of the noise, the exhaust heat shields and brackets all seemed pretty sturdy and intact.

Just this past week I've been haveing some unusual vibes from the bike right around 2,700rpm. It's similar to the standard vibes around 4,500 but more intense. The tank and everything buzzes. Anyone else having or had something similar?

My 919 vibrates right around 4500 rpm's too.

I don't think too much of It, though.

Does anybody have vibrations at 2.5 a 3k ?? I know it does between 4 and 5 no big deal but should I be concerned about that? Are there any noises that let you know when to do a valve job?

Sorry to revive an old thread but because it's been a few years, maybe someone has worked out what causes the buzz at 2700rpm? It's not a huge deal but if it's a 5 minute job putting a rubber O ring between a washer somewhere then I'd be really keen to know!

Thatís literally the only common weird rattle/buzz point on the 919, provided all other fasteners are properly torqued.

If you have handlebar buzz, that is another story.

When I was using the stock headlight there was a buzz/noise coming from the headlight rim at certain revs.

FWIW, my bike, which has a hell of an interesting life, benefitted a lot from me going through and just testing all the bolts. Getting them to the correct torque is great, but the first pass on a used bike should probably just be a test to see if anything is sitting there loose. There's more trim bolts than I expected, and the bike itself is vibrate-y, so there are a lot of opportunities for weird phantom noise. One of the mounts for one of my pieces of trim was ground off in a crash at some point, and so I didn't realize there was a screw missing, and that gave me a weird buzz at speed.
