WOT A/F is 13, power valve and secondaries are verified engaged, all secondaires open full on a hard pull to 5500 but maybe that is just a loose setup. 80mph cruise no load is 14, rpm's are about 3300, not in to pedal much though - twin carbs 1:1 linkage. A/F seems to slowly drop after 70mph to ~14 at 80, rarely run there so not worried.
If I was a pro like some of these guys I bet this setup could make some good power, it is decent down low and just loves winding out to 6k pulling hard the whole way, starts to break up around 6200. I did a fair amount of head int./exh. porting and matching, gut tells me it breathes real well. Yeah I know, gut means nothing.
