      Look around for secondary air valve adjustment video, It may not be opening properly, Most emission rated Qjets are too tight after cam/intake/headers/exhaust.

      The best thing I ever did for my engine was give it an electric fuel pump and all new braided houses and A/N fittings. I also run 5 gal of C10 per tank to dilute the ethanol even further. My engine loves it, and I love the smell lol!
