Before my question, let me put a disclaimer in. Most of the bikes I've had in the past had fuel injection and shaft drive. Ok. That said, my '06 Speedmaster has what I can only describe as a lag and a surge. It's had this from day one. I notice this mostly in the lower gears. It's quite annoying. I recently changed my pipes an re-jetted the carbs, but no change. I adjusted the chain - still no change. Is this a normal by-product of carburation versus fuel injection or is something else going on? This happens when I roll off the throttle and roll it back on. Any suggestions?
