I had a littel decel popping with 2.5 turns on pilot adj.. But it just didn't seem to come on. So I moved the CDI setting up to 7 from 6 (eight would not start with the adjustment I had) seem to run a lot better. But more decel poppeing. May need to adjust more but she sure runnes good 90 + MPH getting out of my confort zone with a sidecar. Rudy
