Hey all. I hear a slight knocking on my bike. If I'm facing the bike it's most clearly heard from the left side. The valves sound really nice. I've done the chain tensioner mod which is on the other side. Maybe I just need to rebalance and idle the carbs? It's not that there's any problem right now I would just like to prevent a complete rebuild or some kind of worse failure on a trip. Any advice would be appreciated. Thx.
