Moped Exhaust

The exhaust of my St Tomos moped 2000 miles is blocked, it is a sealed unit and I can not find a way to go in the exhaust to clean it, there no screws, bolts or nuts just the hole entrance and the exit hole, could you please tell me how to clean it, I'll appreciate your help, thank you.

you can not open it. how to clean 2-stroke exhaust is to put a liquid inside. I think it was hot caustic soda solution, but check with someone else before you use it.

exhaust hangs if you use cheap oil or oil mixture is wrong, or moped is still driving too slowly. You can remove the exhaust from the bike as fast as it can go half an hour.

take the exhaust and run solvent through it.

At the outlet end of the exhaust gas, in some models, there will be a screw to remove the exhaust system. Remove the muffler, clean. Just use a solvent to remove the exhaust. The exit is blocked in 200 miles? It is under normal conditions? It seems a little too early. Please check 2T oil you use.
