Well now...took a ride this evening, temps in the high 70's, clear and dry. I think I finally figured out why my cruise AFR's have been richer than I want with the v-stacks in place & using non-E gas. It's also on the rich side up-top. And the pilot circuit is about as lean as I want to take it. And the v-stacks are likely making more efficient use of intake air. Non-E runs richer in carbs than E-10. Looks like it is time to go slightly smaller on the main jets. Yes, the mains. That's my theory, anyway. I may not have the chance to ride for awhile due to other commitments, however that theory is gonna get tested...
