possible exhaust leak
test it when the scoot is running take a wet rag and plug the end of the exhaust
if it kills quick then you are sealed up tight
If not then you have a leak
To track down the leak the same way you find a air leak in a tire
with the scooter running
Take a squirt bottle filled with soapy water and squirt it by where the connection of the cylinder to exhaust pipe is and see if it bubbles up.

I might give them a tighten again. I know over time the gasket beds in and you need to tighten it so I might go do that  |

test for exhaust first before tightening the bolts you dont want to overtighten.
Dont fix what aint broken is what my grandafather taught me
a exhaust leak at the head of the pipe could definetely cause this .
I have had a similar mess underneay=th my scoot from a small exhaust leak send out some oily spooge .
If it has a small leak at 8000 rpms it is going to send a oily mixture out .

Any extra air coming into the cylinder either from a intake leak or exhaust leak would cause fuel mixture to be leaner causing over heating
