Port out the carby end of your intake manifold to make it the same size as the carby outlet. The manifold is a few mm smaller all the way around which in turn increases the amount of turbulence, as the air hits this lip of the manifold it bounces back towards the incoming air creating turbulence and disrupts airflow.
Use a rounded file until you get the right size and then sand it smooth, i started with 80 grit paper and went right up to 2000 grit for a smooth finish.
I was riding on tuesday at a place near where i live and there was 3 other standard orion's, a couple of times they tried to race me and my bike pulled away steadily from them along the straights, i also have a uni filter.
