Hello all, My bike has developed a knocking. I have adjusted the valves. All the valves open and close and the clearances were checked. I also don’t have any vacuum leaks in the carb boots. I was told it could be from non balanced carbs and I plan to sync them soon. I doubt that is the problem though. It’s really hard to judge where the knocking is coming from. It seems to be coming from lower case and transferring up to the valve cover. I really can’t figure out if it’s at the valve cover or the lower end. Does anyone have an idea on what could be causing this? I’ll post a YouTube video below. Thank you!
