Default new 70cc

hey i got a new 70cc motor to replace my 50cc motor that had done over 5000 kms. I am running in and understand that it will get more power after run-in.
But I have no top speed so i drilled some holes in the cover and it did improve, I can ride ok but i would like more top speed it seems not to be getting much air.
Could anyone help me get some more speed and make it breath a bit, Thanks
