Thinking I may have the broken or worn alternator chain/tensioner issue. Bike is an 86 with 62,000mi. Am noticing very sporadically maybe once every couple minutes, it will make a single tap/click sound and the rpm will slightly dip. Sounds like it is coming from the lower right side of the engine. This happens at idle, have not noticed anything odd above idle, bike runs great. Have also noticed it seems to make a slight clunk right after hitting the starter. Before I pull the cover, Does this sound about right?
