I plan on taking off my 12mm 913 pump to be benched and built by someone around Christmas time. Looking to pump more fuel yet keep it streetable. From my understanding not much work was done on this pump from the get go and it (back in the day flowed 400cc or so) I don't think it does now considering how lean it runs on fuel. I hear Brad Ponci is a good guy for 12mm pumps.
