After I lubed my splines, the bike now makes a squeaking sound. Almost like a rapid chirping sound. It is not constant, it happens sometimes when I have the clutched pulled and sometimes when it is neutral, but little more often when I am under power.

It is not the 3k-on-the-tachy thing, cause it happens before 3k. And it seems to calm down some when I am under power.

Any thoughts what could cause this? Perhaps I did not tighten bolts enough and there are metal bits vibrating?

Any advice would be appreciated

I assume the squeaking/chirping is coming from the rear wheel, final drive area??
I have never heard of this problem before.

Did you follow fergy`s spline lube procedure, including wibs recent addition for cleaning and lubing the final drive to wheel hub?

I`m wondering if the noise is somehow related to this part of the recent spline lube.:confused:

Unless the bike is rolling when you are in neutral, there is nothing moving from the front of the drive shaft and swing arm on back when the bike is in neutral. So the noise has to be coming from somewhere from the tranny or forward, IF the noise is there when the bike is in neutral and not moving. I know this isn't much help finding the problem, but hopefully it will eliminate a good portion of the bike from being the possible problem.

Rear brake needing adjustment?

Yeah, it makes it on occasion when it's in neutral. So I had assumed it was nothing in the drive shaft. It is disconcerting, but it sounds very much like metal on metal. The bike runs absolutely fine other than that very disconcerting sound. It makes it less disconcerting that it is not final drive/ wheel.

I did follow Fergy's directions (thanks, pictures were awesome). It all went well except for that one time that the rope holding the center stand loosened and the bike lurched forward. Back tire was off, so it didn't go down on its side, and I mostly caught it. Knocking something during that that could have been the cause of the sound.

If it makes the noise with the bike sitting still in neutral, how can the rear brake be squeaking?
Can't disagree but he really doesn't say the bike is not rolling in neutral. I think it's a rear brake problem caused by removing the tire or re-assembly. jmo

My bad, I should have been more explicit. It definitely squeaks at a standstill. It squeaks a bit more when it is moving at slow speeds, and tends to stop at higher speeds.

I had a similar issue. Never figured out what it was. Squeaked at standstill, increased up through about 3K RPM and then disappeared. Sounded like a mouse.

After about a month and 1500K miles it went away

Never figured out what it was. I think mine started after coastering/degoating. But I had just done a spline lube and changed all fluids 2 weeks prior

Sounds like a vibration issue. Unfortunatly it can be any number of things. The best way to try & track it down it to have a second person rev your throttle for you while you listen around the bike & try to narrow down the location.

I've got a rattle I simply can't find. I think I'll make it a game at the Gathering & see if anyone there can figure it out. Basically, rattles can develope at any time & it's likely not related at all to your recent work. Find a buddy & check it out. :)

Sounds good, thanks guys!

I found out one more thing this morning. When it is on its side-stand, I cannot get it to squeak at all. Seems like a screw loose somewhere. I'll check all the bolts and make sure there are no loose ones. Other than that, I'll not worry about it. Looks like all is well for my trip this weekend!

Thanks again for all the help.

Totally stumped on this one now. You didn't have the noise before. All you did was unhook the brake, remove the tire, undo 4 nuts and grease the spline. Nothing really changed except possibly the rear brake. It would not squeak at standstill however. :doh:

lol, nice catch. Figures, since I work in uHTS (ultra High Throughput Screening - look it up if you care) I deal with massive amounts of numbers daily. If I screwed one of them up at work like that it would make for real big problems. Maybe I should hire you to proof my data analysis
