Overall it looks good.
Your opinion?
Additional gasket under CYLINDERS!
Alien (NOT ORIGINAL) Piston???

That cylinder base gasket does look funny, but if you pull the cylinder to check the rings/piston and rod/pin then you will need a new gasket anyway.

I've seen grid/screens that look worse, no signs of major problems with yours.

Replacing the seals is a good idea if you think the ones you have are original. I replaced all my 25 year old internal seals that are only accessible when the engine is apart.

Your chain looks normal to me. Here is the parts list:

The chain does touch (slide on) parts #8 and #3. #8 can't be removed until the head is off the cylinder. Watch out for part #11, it's easy to loose.

Also, watch out for the oil filter output bushing with the O-ring on it. I see it in your photo, and it's also easy to loose.

When you get the valve cover off, you can then check to see if the cam chain is stretched.

Question

My cylinder has a 3 base gaskets.
Number 1 and number 3 is thin and soft gaskets.
gasket number 2 is made of aluminum!
I think the engine put nonstandard piston. ?????
To exclude the impact (meeting) the piston and the valve was set (attachment) gasket number 2 .????( this is my opinion)
What is the opinion of a guru?

That is beyond funny. I would say that you need to pull the head and cylinder to see exactly what is inside.

No need to check for cam chain stretch now. With the extra height of the cylinder, I'll bet the alignment marks won't line up properly with a new chain. I'm not sure how you would check for cam chain stretch with that extra set of cylinder gaskets. You would need to know the starting alignment when the cam chain is new and with the aluminum cylinder spacer installed.

I had one free day and I spent it with my bike.
This day was difficult for me.
I checked Cylindercompression. It was hard. 30 minutes of jumping but the device showed only 8 kg / cm 2, it is not enough.
I am very upset.

I took the engine out of the frame (it was easy to do) and opened it.
When I saw the engine in, I became very angry !!!!!!

I want to tear hands mechanics, who collected the engine in front of me.

It's horrible, it wanted to kill this engine !!!!!
1. Part of the fastener head cover, cylinder head and lost and replaced by strangers. I'm surprised! Where native bolts (hardware)??
2. Single bolt cylinder head was not screwed in (only by hand). The mechanic had no memory??
Mounting bolt cylinder is shortened. Why??
3. Everywhere (everywhere) snot on the sealant.
3. The ends of the release valves were shortened ??????
4. ARM EX.SUB ROCK - has a great point wear !!!!! (A bad valve adjustment!)
5. Chain tensioner received many blows with a hammer !!!!!
6.Piston and the cylinder has a large scratches, but the rings are good. Why??
Small gap between the piston and the cylinder (the error in grinding??)?? or is it mud sand) in the assembly??
7. Piston clean without soot but has traces of blow valves!
Who can identify this piston? This WISECO??
Now I am left to disassemble the cylinder head and I'll have a lot of questions in this forum that I should do next.
