For a month the kick starter spring was abit weak, it was not springing back very well.
Then I went for a ride and after one hour, the engine got jammed stuck. It turns out that a peice of aluminium as big as an aphid came off from the top edge of the piston and scraped inside the cylider.
I changed the top of the engine and I noticed that the kickstarter was stiff, taking about 40 pounds to turn around.
So i took off the top engine and tried the kickstart again, and it is indeed very stiff even with piston running without the cylinder.
What could be the trouble? the bike is a Peugeut Trekker that is about 20k miles.

Could be the crank bearings, best way to check if it is the CVT or the CRANK is to take the CVT cover off and see if you can turn the VARIATOR by hand. You should be able to turn the Variator by hand if nothing is binding the Pulley and or rear Clutch pulley making it hard to turn.

When you get the CVT cover off, check the kick starter mechanism for threads from your belt. When my belt began to fail, a bunch of strands from it got wound around my kickstarter gears, causing them to not spring back and often fail to engage, or be hard to turn. As soon as I cleaned them out, it was all back to normal.

Thanks for the brilliant suggestions!!!
I fixed the kick starter, but the engine sounds pretty wrecked.
Fixed the kickstarter spindle gear by oiling the friction zones which were clammy.
However... There's bad sounds coming from the engine, the revs are not regular because some kind of vibration/rattle is stopping it from turning perfectly, and there's a sound like a cracking plastic every 10 seconds irregularly, a bit like ball bearings grinding and popping, or any kind of metal clashing.
Could it be easy to fix?

Can you post a video of the sound? Some of our forum members are pretty good at diagnosing by ear, even on video.
Right off I would say the kickstarter gears are out of alignment, possible attempting to engage while running, but need to hear it to get a better idea.

Thanks, i don't know where i've put my keys... will send a video when i know.
because the piston hit the top of the cylinder lid and seems to have chipped, and the kickstarter spring is okay, i think it's serious.

It's my scooter... I still didnt find the keys, i must have been acting melodramatic when i heard it was messed up because i lost them in the house. There was crazy shuddering across all the crank zone/lower engine that slowed the revs down and the crack of bearings slipping in top of each other  sry i can't record it without the keys ... still i got 32k from it ) it would be 50k if the crank doesnt give out. |

32k miles!! That GY6 doesn't owe you a thing!!
Wow,,thats about all you will get,,if you get more than that you are on borrowed time..
Time for a new motor..$300 from ebay,alot easier than doing a rebuild and less time consuming unless you want to learn about rebuilding a GY6 from crank up and thats only if your cases are in good shape:)

20k miles sorry for vagueness, it's pretty good for a scooter. I found the keys again but i don't want to start the scooter because the previous had a bizarre crack consistent with impacting the top of the cylinder and it makes such a messed up sound i think i will damage the new piston if i try to run it for recording the sound. it makes two types of dodgy sound simultaneously including a rhythmic cracking sound and a random lateral vibration of the main engine :!!! catastrophic...
I'm searching for a scooter with as much part compatibility with especially because i have sports rallly suspensions on the damaged one, and i think awesome suspension is the best possible thing on a scooter.
