No ear shave. Carb vent line is running under seat and down, not exposed to any wind. Same place it was before I removed the carbs. Replaced tee with a larger one, still the same. Starts right up, can rev it up sitting there, but when take off down the street it just tops out at 40 mph and about 4000 rpm. Engine runs completely smooth, no sign of bogging like out of gas. Thinking maybe float adjustment? But both being out the same seems unlikely. I could see one which may have one cylinder not running right. I'll double check the boots and the vac port to be sure it's capped off completely. sigh...funny thing is, I have a vtx 1800 and a dyna superglide and I like this better than both.
