No didn't. sound was before and after changing the chain! That was the reason why i did change the chainI though was the chain but was not! Sound its loud on 1st gear and 2 but more up is more quiet

Please only post video's from your bike,

Your noise sounds/ looks like your missing a tooth in the gear box, (which is very, very rare)...

And there has NOT been any abuse just prior / wheelies, correct?

Let Finalimpact weigh in.

I suspect I'd probably be pulling the oil pan and looking for some debris/ tooth.

I believe you can see at least part of the gear box looking upward..


**Try holding the shaft in the center of the clutch, (remove all the plates)-(that shaft goes direct to the box)

Put in first gear..

Now, with hand resistanced on that shaft, rotate the rear tire slowly forward keep "tension" on the gears. What I want you to feel(and perhaps hear), is ANY space, again, if a tooth in the gear box is missing, you should be able to feel the shaft jump or skip...

Ok no more videos frome not my bike. Sorry.
You are genius. I will do that because if tooth is missing there will be some space. Also if is missing tooth the space should be in some places not everytime i spinning but just some time some place? Right?
So if i hold clutch hub all should stay in place 0 movement. If. Kt then your theory will be correct. Will do it tomorrow!!!
 
The smaller center hub goes to the gear box directly.

The outer clutch basket goes direct to the engine.

The clutch plates, when pressed together with the clutch springs, connects the two.

As for the above post ^^, yes there's a tad of back lash play in the gear box however, if your missing a tooth
inside, they'll be a real large gap at that one spot. You can also simply rotate the center shaft(inner clutch hub) while in gear
, there's some drag with the chain and rear wheel. If a tooth is missing, again, you'll feel it jump a decent amount...

If /when you find you that space(its broke), you should be able to rotate that shaft back and forth in that gap. then say
you rotate 180 degrees, where the teeth are good, you won't have that "gap"..

In neutral, your bad gear is not engaging(or "involved"), thus no noise..

As a side note, I blew my second gear idler (lost a couple teeth) on an old yamaha 125cc simply coming off a jump
(this is back in the mid 70's). It was hard ground I landed on and apparently enough to bust the teeth off...
 
Will check it out today. But (again) :) . If is tooth missing that will be on one gear not on all of them? The clunk is on 1th gear till 6th.
So I should put back the clutch hub ( small one what is inside the big) and start rotating (clutch hub) with gear on. And I should feel some jump if is tooth missing? Is that correct?

Also when driving there is no strang sound! When driving it's quite and nice, so missing tooth will give some clunk sound all the time?

I really wish you would simply try this...

I've explained several times but you keep trying to find reasons not to...

It depends on what gear it is (if its even a busted gear)

. You can button it up and run it till something bigger lets loose (maybe), it'll be easier to find then...

Shouldn't be anything wrong with asking questions? The moment when i will be outside checking as u said i will have questions so if i ask more now i will know what i do and what im looking for.
Simple thinking: if tooth is broken then will be only on one gear or on all? Etc.

After looking this over, I strongly believe that what we are seeing is slop in the dog clutches. With the engine off, the bike in first gear, and the clutch engaged, she will rock back and forth a considerable distance.

In a constant mesh transmission (especially one with a wet clutch) I find it highly unlikely that you are going to break a single tooth. the problem cascades....one tooth breaks, increasing the stress on the remaining meshed teeth, causing yet another tooth to depart..and so on. Sadly, I have seen this first hand.

So I expect some slop, and a different amount in each gear. What I don't know is whether the video shows too much slop, too noisy slop, or both. I need to do a test when I get home tonight to see.

Question for the OP.... Did the bike have a problem like popping out of gear?
 
Thanks for interest in that tooic.
Bike runs well its only the clunk sound when is start running from full stop. It's giving that clunk sound and is loud but after is quite. No popping out gear or so...

Never say never, but I can't imagine it's dropped a tooth off. Its a constant mesh box. All 6 gear sets are constantly in contact with each other. So ya, under load it would sound like hell when those gears are doing work. And when not loaded you would still hear a constant clash of missing tooth/teeth coming together.

Im not sure what it is but seems unlikely as it would never be quiet.

Have you drained the oil yet? Maybe cut open the oil filter and inspect it for particles.
 
I have that bike about 7k already made it by me. And that clunk noise was another project of my. So there is about second oil chenge.
But I didn't see any thing when i was draining old oil from it. Make me so so sad thinking to drop the engine for reparations!
 
Find the weakest link....
