Weird noise after chain has been tightened

[hojlind]

Hi all

I just tightened my chain today after a trip trough europe (5000 km) but after having tightened the chain when pushing it without the engine started it makes a weird noise as can be heard below:

What can be the cause of this? I checked my if it was because my chain was too tight but it has a little over 20mm of play, which is what the service guide specifies (20-30mm).

Any help would be much appreciated

Vid is set to private...

Is it kinky?

Head outta' the gutters, guys!  THE CHAIN, the chain! Is the chain kinky and causing extra noises from tightening and loosening as it turns around the sprocket?...

It seems it is still processing, i have just made it completely open so it should be watchable now.

I am really very far from good with engines, how do i check if that is the case? will i see the chain "jump" when the wheel is turning?

[hojlind]

Okay, so i just tried seeing if i could figure something out and it seems that the chain is tighter at certain points in the rotation in comparison to other points in the rotation. (measured at the same physical place of course)

It's wore out. Needs replacing, with sprockets.

[BockinBboy]

Yeah, that's what I was describing with a 'kinky' chain.  Typically once a chain starts doing that, it will continue to do that and needs replacing.  The routine is to replace sprockets along with the chain for the best wear and longevity out of both.

Well that sucks, but thanks a lot for the help. Considering I went 5k kilometers while being very far from nice to my motorcycle and I don't know when it was changed last it seems realistic that now is the time to change it

can you make the video so its not private I wouldn't mind hearing what it sounds like for my own reference. Since we are on the topic how long does a chain usually last if well maintained?

Those of us interested in starting a circuitous, never-ending argument would like to know the make & model of your current chain and what you used to lube it with.

When I adjust my chain to the min deflection (20mm or .8 inches), it makes noises.  So I leave it more on the loose side.. 25mm to 30 mm.....1 inch to 1.2 inch....

If you have tight and loose as you rotate the wheel..you have to adjust at the tightest place to 25mm ....

Too much variation from tight to loose means tight links.(replace chain)  or out of round sprocket(s)...replace sprockets and chain..

Can't see video to hear exact sound...

But logic...if chain made no bad noises...then you tightened chain and got bad noises...cause is too tight chain  (but actually caused by bad chain and / or sprockets)

Thank you for this reply, twocool! I was freaked out last week because of this noise, now it's gone.

Just a reminder that we need to adjust chain to (minimum) 20mm WITH YOUR WEIGHT ON THE BIKE.
The chain GETS TIGHTER with your weight on the bike.
A bit awkward, but sit on the bike and reach down with your left hand to test the chain freeplay.
Easy, but easier if you have someone to help.

This is incorrect information!  Use owners manual! Or use shop manual...

ADJUSTING
• Loosen or tighten the chain adjusting nuts ® until the chain
has 20 - 30 mm (0.8 - 1.2 in) of slack at the middle between
engine and rear sprockets. The mark ® on both chain
adjusters must be at the same position on the scale to ensure
that the front and rear wheels are correctly aligned.
Place on side stand for accurate adjustment.
• After adjusting the drive chain slack, tighten the axle nut CD
securely.
• Tighten the chain adjusting nuts securely.


OK...that's the quote directly form the maintenance manual...it plainly says "place on side stand for accurate adjustment!"

Drive Chain Adjustment
Inspect the drive chain slack
before each use of the motorcycle.
Place the motorcycle on the
side stand. The drive chain
should be adjusted for 20 – 30
mm (0.8 – 1.2 in) of slack, as
shown.


And..here is the quote directly from the Owners manual..

I'd agree with checking it with your weight on bike.
I lowered the rear 1" (links) for my daughter. The chain was tight in this position just on side stand and had to re-adjust it.
This would simulate your weight on the bike.

[twocool]

The post below makes no sense....please...please...stick with the owners manual and the shop manual ...

If you adjust chain to 1" or 1.2" slack with riders weight on the bike...the chain will be dangerously too loose when the suspension is unloaded, like going over bumps....chain could come off sprocket etc.

Yes.  I follow the shop manual and adjust while on the sidestand.
