That sounds like either a ring broke. Or rings are so bad that the Piston is slapping cylinder walls.

Club Tomos is a joke

So?? What was making all the noise? Did you take the top end off and look at the condition of your piston and rings????

Hey. I removed the cylinder and found that everything seemed to be fine with it, the piston was also fine and the rings were not broken. However, there was not a single gasket! Under the head and under the cylinder was just a sealant. Now the question is if I cut the top head pad out of aluminum, what is the thickness? 1mm? How thick should the bottom gasket be? Here in Russia just thick cardboard is often used (for bottom gaseket). And in appearance, this piston does not look like the original one from TOMOS.

Good. Thanks. But the question is, why do I see head gaskets on sale?

I don't know what you mean by saying head gasket on sale. You only need Base gasket if everything in good condition. Make sure you only use 9 ounces of transmission fluid. And if the noise is affecting engine performance. Do as other guy said and look for abnormal movement in crankshaft. Make sure you pay close attention to where parts go if you take apart engine!!

Do you have Auto parts store in your area?? Go see if they sell gasket paper and Trace it and make gaskets for anything. I've made gaskets for my clutch cover on my tomos and they last longer than original.

Those are fine bearings. Used in many engines. To replace those bearings you are going to be tearing the entire engine e down and even splitting the center cases to remove the crank.

Heating up the cases in the oven will make the bearings easier to remove, and warming up the new ones will make them easier to press in.

It sounds like you are limited in resources to make this happen so just be sure to take your time and ask questions if you run into any problems.

Uh oh. That's not good. Sprag clip? Check your Piston clips of missing chunks too

I imagine that your sprag clip broke. The sound you are hearing may be the shaft sprag thingy getting angry(unsure of correct term)

I could be wrong, but that does look like the end of the starter shaft sprag clip. On a pedal start bike it stops the pedals from turning with the engine whilst riding. I'm not totally sure a kick start bike even has one.....

If so it's not the biggest deal.

Hooray I was able to remove the clutch !!! And it looks good. There was a single spacer under the clutch (it hangs on the shaft). All bearings look good.

I think, maybe you need another spacer for the clutch? (edited)

Ha ha manual? All I have is youtube, and kind people write to me here.

Yes thank you! of course I have same guides.

However, they do not provide repair support, when you do it the first time.

It's just mysticism! Put the clutch and there was a gap!

Early the clutch rubbed against the gear. (edited)
