Set up the primary bbl for economy and secondary bbl for power........
Well that's the thing you can get different main jets, which affect the primary side, but that's about it other than tuning the timing of the secondaries. I have some more carbs I can take apart and see if they have different sized needle/seat bits but that's all there is available.
I am really happy with the power at this point but 10-12 mpg is not going to cut it for me. I would rather sacrifice a bit of power and pick up 3-4 mpg if I have to choose.
