Hi, need suggestions for ballpark jet sizes. 81, BS 34's with xs performance 750 big bore, 277 rephased crank and cam, pamcopete ignition, emgo pod filters, 1 1/2" headers with prforated baffles, no muffler. on inspection my carb jets were not stock,(changed by some previous owner) 140 main, 135 air jet with a stock 42.5 pilot jet. I live pretty much sea level. Anyone out there running a similar setup with their motor? Would love to hear what you guys are running as far as jets.
Otherwise I was going to go back to stock for all sizes and try and figure out where to go from there?
