Hi, new to the forum. Had a friend suggest. I have a issue with the engine. 117 California S&S, on my 2005 Bulldog. When at 70-80 in 6th gear, I get a pulsing of the engine like it is starving for gas. Tried resetting the carb to factory spec's and tuning it in. Runs great when on the throttle or idle, but steady at 70-80 bucks and kicks like it's running out of gas. Any ideas?
