| theres a sharp step where the crankcase enters the side boost port thats very rough. i got bored and attempted to mill that off then smooth it out with sand paper to smooth the flow ALOT but never got into it properly.
but id imagine aside from that theres not much you can do to those motors porting wise. just have to fiddle around with squish settings.
