Quite a few number of possibilities:
1) You're not getting enough fuel (your carburetor may need adjusted)
2) You're not getting enough air (your carburetor may need adjusted, you may need a performance air intake)
3) Your carburetor:
may not be able to keep enough gas in the fill bowl to keep up with the fuel need of the engine
same as with the float type, but the diaphragm cannot pump in enough fuel to the carburetor to keep up with the consumption of the engine
4) Could be a problem with your CDI if it has one. If it does, might want to look into upgrading to a racing CDI (and the speed\rpm governor\limiter might also be a part of the CDI which might be what is cutting you out when you go above 40-45mph)
I can't give a definite answer but hopefully the above checks will help you out.
On my 49cc scooter engine the carburetor is found on the engine. The engine is broken down into 3 parts, the part to the left (looking at it) where the air filter is is right next to the carburetor.
