adjusted chain now weird noises

[Lunatic]

anyone in the innaloo area mind having a look at my bike.
i lubed chain and adjusted. followed psber's kind guide lines on how.
now i have a weird "rubbing, clunking, chain knocking" noise if anyone has a spare hour or so to look over see if there is anything obvious that i cant see.
be much apreciated, can pay in beer.
cheers Tic

Sounds like its too tight
did you check the freeplay AFTER you tightened the rear axle?

[Rich]

Turn your wheel and check you chain tension at different spots in the chain...

[Hewie]

Check for seized links too

[Lunatic]

i checked when wheels on ground (not on paddock stand) there is bout 40mm or so. and when i learn on rear there is bout 25mm or so.

[Rich]

Yes but do that in several different spots on the chain...

[Lunatic]

ok should it be bout the same all the way along.

[BigTim]

What Rich and Hewie said about seized links or areas of chain is a good start.
Also check to make sure your rear wheel is straight in the swingarm. If you wound up one side's chain adjuster more than the other, the wheel (and sprocket) might be out of alignment and start causing weird noises.
There should be some sort of marks on or near the adjusters. Make sure they're the same on both sides.

[Lunatic]

ok no worries, i thought i had adjusted properly, the markings and guide don't seem to flash, i'll check that tomoro arvo aswell

[g0zer]

i reckon loosen everything off and start again

make sure you align the rear axle so the rear sprocket is nice and straight.. did you use the big screw driver in the rear sprocket to keep everything tight and straight while you do up the axle nut?

also i thought you normally want about 25mm vertical play not 40mm?

[BigTim]

Yeah, sometimes the markings are pretty poor. If you have access to a set, grab some vernier calipers and measure off a set reference point on each side, to make sure they're the same. I use them to make sure I get the rear axle as close to aligned as possible.

[Lunatic]

screw drive in rear socket? no didnt do this, is that 25mm unloaded, or with me on it?

i'll do it over tomoro. and see how i go, hopefully i dont come back saying the noise is still there.

cheers

[g0zer]

i set 25mm unloaded on the side stand

umm how to explain, when you do the axle nut up nice and tight it can shift the axle position away from where you set it with the adjusters. to stop that from happening you slot a BIG screw driver (whose diameter is about the same as the circle that is a sprocket tooth) into a tooth and wind the chain onto it.. so it pulls the rear wheel tight up against the adjusters.. so when you tighten up the nut it cannot twist out.

25 unloaded. beaten

[Lunatic]

o yeah i kinda see what you mean.

is that 25mm from centre both up and down or 25mm from chain slack up to down. i did the latter

[Castor]

Hi Lunatic. If you have drama's drop a line in here or PM me and I can come around and do it for you at some stage tomorrow.

If needed let me know if you have tools or if I should bring mine.

Good luck.

[Lunatic]

o yeah cool, i'll have a look at it tomoro. if i dont succeed i'll drop you a line. cheers

[Lunatic]

dont have time to re adjust tonight, but i just went and checked, and i was turning wheel and the chain at some point is around 25mm ish then it tightens right up. im guessing its a seized link, how do i fix this. ??

[BigTim]

You can try giving it a real good clean with kero and a toothbruth, and try working the frozen link back and forth to loosen it up (bringing the wheel forward in the adjusters will probably make this easier).
Otherwise, you pretty much have to either accept that it's on the way out, or replace it.

[Lunatic]

bike is not even year old. hmmm think i might have some work to do on weekend,
