with 6x 1000cc systems are you not concerned with flowing 2000cc of fuel through the smaller, less flowing primary ports?

I was discussing with Paul Yaw the possibility of going 4x ID2000, or even a simple 2x ID2000 system and he said that even though it will work it wasn't optimal because 2000cc fuel was too much for the primary ports and would not mix well. He said a better match was 2x ID1000 and 2x ID2000.

 

^That's one way to look at it. There's pro's and cons to it, you've discussed something I was partially concerned with. I don't want to argue over it but I still think it's a worthwhile mod if you don't want to dish out for 2000cc secondaries...
