i have a 03 600rr and a two weeks ago i noticed when i got on the bike after work that when i started it it was idling at 900-1000. my hot idle is set to 1400. in the past the bike has akways had a higher idle at start (2000 or so). ive changed the oil over to a full synthetic but that was about 1200km before this happened. about 3 days ago i came back from a drive and when i pulled into my house i heard a slight ticking comming from the engine. its not overly loud but it is a noticeable difference in the engine sound. are these two related or separate issues? any ideas on what they could be?
