okay, so i cleaned, adjusted, and then lubed my chain yesterday. this morning when i took off to work i noticed my chain was making a "whizzing" noise, didn't sound terrible, but i have never heard this before?

when i adjusted the chain i checked slack in the middle of the of the chain between the front and rear sprockets (~14 inches from center of rear axle) and i checked it and adjusted it on both the side stand and rear wheel stand (measurement was roughly the same). i don't think i got the chain too tight, i set the calipers i have to 1.2" and used that as my guide. also after checking the tightness i looked down my chain and sprockets to make sure that they were aligned, and they looked fine to me, i also used the tick marks near the axle as a reference.

and for other informational purposes i used an o-ring safe motorcycle chain cleaner, then i lubed it up with the dupont multi-use teflon lube in the blue can.

anyone know if this is normal for a clean chain? what else should i check?

oh and i also checked the chain stretch, and it was under the limit.

thanks!

Chains wear unevenly. Check the slack at 1/4 turn intervals of the rear wheel until you've run the chain all the way around and see if there is a tight spot. The chain should be adjusted at the tightest spot in the run.

Check to see if the chain is running centered on the rear sprocket.
Personally, I consider 1.2" too tight.

1.2 is a little tight, I set mine at 1.5. Grey wolf is correct. Look for tight spots.

I do this by having someone spin the rear wheel slow while I hold a smooth metal bar against the chain applying some tension and feel for where the chain moves the bar.

What's the best way to check for alignment on the rear sprocket? Did someone do a write up? It visually looks straight but I could see how it being off could make the noise.

I also checked for tight spots and at it's tightest is about 1.2 inches.

On my DL1000 it was making an odd sound sort of a whir . It turned out to be the cush rubber bumpers were worn out.

are you referring to the rubber on the front sprocket?

or what rubber bumpers are you referring to?

Rear wheel behind sprocket carrier. When you pull wheel, the sprocket carrier comes off and you will see the offending parts.

The adjustment markers are slightly off on my bike, sooo ...
I put mine on the centerstand and roll the back wheel, watching that the rear sprocket teeth stay mostly centered between the sideplates of the chain.
Speaking of centerstands, I sometimes mistakenly assume everybody has one. If you don't, checking alignment might be difficult.

 

[bassbronco_74]

i have a rear wheel stand which is what i have been using for all of this. and i too realized that the marks are a bit off, because i have it what looks to be centered and straight and my marks aren't quite the same.

i have tinkered with the chain some more, made some small adjustments and lubed it up quite a bit more and the chain noise has seem to quiet down/go away so i am thinking i might have been slightly out of alignment, and lacked some lube (even though i feel that i put plenty on after cleaning?)

still am planning on checking out that rear sprocket carrier just because now too

thank you all for your input and help, of all the forums i have been a part of, this is by far the best community and the most helpful ones of all. :mrgreen:

thanks for the tips.

Ah, you're good with a rear wheel stand checking alignment, forgot about those things.
Check your chain tension after 500 miles. Whatever it is at that point, that's what it's happy with and what it should be adjusted to when you feel the need. This is assuming the alignment is correct.
RE carrier bearing.
I grease it at every rear tire change, which is about every 7-8k miles. Did this just today for the 7th time as a matter of fact. Don't know where the grease goes because I get quite a bit in each time.

Same issue.

I also have this issue to a small degree. I started noticing it right after the first time I cleaned and lubed the chain. I didn't have to adjust it so I'm sure I didn't change the alignment.

The noise is very slight, and only noticable when riding beside a car or other bike. Everything seems to be properly aligned, I'm not noticing any stretch or other damage to the chain.

I just assumed that a slight amount of noise was normal from a chain drive.
