Hey guys I'm new here and to riding. I bought a 06' BF750 and it ran great. We made a couple of rides and had no problems. Unloaded it the other day and when to start riding and it is making a knocking noise when accelerating not when idling in neutral or being revd in neutral either. I changed the oil, took the carbs off and cleaned them thoroughly. The bike starts right up but knocks when driving any help is greatly appreciated! I found a YouTube video that shows it perfectly. This video is not my bike just the same situation. I couldn't figure out how to put it in here so here is the link. Thanks guys!
