Does it sound like metal rubbing metal, or actuall grinding? Because if something is making a grinding noise on my bike it's being parked untill i figure out what the hell it is.

*Shit happens*

Also when i think of grinding i imagine the sound of a girl grinding the gears in a truck, is that the type of sound your hearing lol?

I went down in a slushy gravel-mud mixture, doing probably around 25 mph. I don't think it was an exceptionally hard crash, but you never know. How hard of a job is it to inspect?
I've never taken apart a clutch but I'm pretty sure you can inspect it and notice anything wrong just by disconnecting the cable and pulling off the cover. Maybe take a picture and throw it up and see what everybody thinks? Don't forget about the oil though.

Also, maybe check the chain alignment. Coulda knocked something out of wack when you went down.

Thanks guys... now I'll need to do some digging into and reading before I bring my untrained hands anywhere near the clutch. It is under factory warranty though, so should I take it to a dealer? Will they complain that since it was dropped, it won't be covered?

Im thinking maybe a loose bolt like on the front of gas tank or your missing one of those little rubber pads that stop vibration in spots like where the gas tank meets the frame. It did it on my old 1997 gsxr750 while idling only, just post a video of the noise.
It would make a difference because if the bike is sitting in neutral and he revs it up to 6k and he doesn't hear the noise, that would mean it's not engine related and would be clutch/chain/sprocket related. But if he hears the sound at 6k rpm in neutral sitting still in the driveway, then it means it is 100% not sprocket/chain related as none of those components would be moving.

Ok but it wouldn't mean that the clutch is bad if he is not using it and it's only in the 6k rpm range and not any other range

Attaching some pictures of what the front sprocket looks like and the side of the crash. If nothing, these hopefully will help eliminate potential sources of the noise.
It was a mostly noise-free return back home following the photoshoot, and I didn't hear anything around that rpm range till I was almost home and then it came back with vengeance.

Hope this will help you chaps somewhat in the diagnosis... any insight is highly appreciated, thanks!

Ok, 6000 rpm, any gear? What about standing still in neutral at 6000 do you hear it? what about sitting still in 1st with clutch lever pulled in at 6000 do you hear it? Report back, nothing obvious with the pictures.

Is it me, or is your chain hanging like a sleeve of a wizard?

Why do you have oil all over the frame, swing arm and back wheel?

Yeah, pretty much any gear, though I've definitely experienced this between gears 2 through 5. In neutral, I hear nothing around that rev range. Even when riding, the noise isn't there all the time, but is present over half of the time. I haven't tried the sitting still in 1st with clutch engaged... will report back tomorrow on that.

I checked the chain slack the other day... was around 1.5", kind of in the higher limit.

That is merely chain lube that got sprayed onto everything... need to wipe that up.

Crashed on the right but grinding sound from the left, are you 100% about that? Is said grinding sound at a slow or fast rate? After you crashed, did you loosen bolts of the axles, engine, forks, etc to let everything "reset" itself from potential tweaking? I'd prob do that first, with the rear wheel esp, and make sure it is aligned properly (via chain, not the swingarm notches) and do an overall once over of everything else without bodywork on.

BTW, I have no f'ing clue either, just throwing things out that make any kind of sense. If you can't get video while riding it, a local reputable shop might be worthwhile

The sound is definitely from low down in the left side, which was what got me to suspect the chain and sprockets. As far as rate, it is a high-pitched shrill, as it you were cutting metal or even welding, thought probably not as loud. It isn't there all the time, but when it does show up, you can sustain it by holding the throttle around 6,000 revs.

I haven't opened up anything else on the bike... don't have all the tools. But it does sound like a good idea, and I'll begin looking into it. The chain alignment is a good idea, and I can do an earlier oil change as well... which is when I can inside the bodywork. Otherwise, it is the shop for me.

Thanks for the immediate advice, chappie... really appreciate all the help!

Could it be the radiator fan making the noise when it kicks on? It could have gotten misaligned int the crash and may be rubbing on something now.

Aside from what has already been said?

Have you put it on stands & spun the wheels, Bounced the suspension?
Looked closely at the brakes?

I'd first check all parts that move.
Have a close look at the linkage, lay on your back & slide under the bike.

& that front sprocket & cover, Cleaner than mine. I think your gtg there.

On more thing, If you take it to the dealer, Theirs no rule says you have to tell em it started after the crash.

"I was on my way to the shop to report this sound when I crashed"

Thank you so much for the reply, OND. I haven't looked at the suspension or the brakes, so will definitely give that a try. I'll be getting my hands on a rear stand soon. Would you advise parking it till I do all of this? The sad thing is I've probably put on 500-plus miles since I noticed the sound... gasp!
