I have a 18 RGS with just over 7K miles on it. I just recently started noticing a chatter/tapping/ticking like noise coming from the right side of the engine. The sound seems to be just above the air cleaner where the upper rocker boxes are. This is happening after the bike has been running for a while and the engine is pretty hot. The sound is only when the bike is in gear and decelerating. If i pull the clutch and let go of the accelerator i don't get that chatty noise, so its obviously when the engine is under load. Yesterday i rode about an hour at hwy speeds, then when i was in normal traffic i started hearing it when i let go of the throttle. Anyone else have a similar experience. Chatty is the only word i can find to describe it. Maybe more like a tapping ticking sound.
