I have a new '06 650R with 1800 miles on it. It's used mostly on the road Today while riding home from work I noticed a knocking sound coming from the Motor some place, while taking left hand turns only. It's a slow soft knocking sound (so it's someplace on the final drive train... ??) and only while turning left at low speed in 3rd gear. 2nd is too slow to get it smooth enough in the turn and 4th is too fast, too Much wind noise to hear it, so I’m not too sure it’s only 3rd gear. Has anyone ever had this happen... and if so what is it? Any input appreciated.
