I've had the bike for 4 days and over the last 3 days did over 500 miles. I got the bike with a 674 miles so I changed the oil and filter. Used Moil 1 10W40. The bike now has 1100 miles. No engine or clutch issues while riding but today after riding 20 miles or so I stopped to adjust the suspension. When starting back up I felt a vibration as though i was riding over a milled section of road. It lasted maybe 30 feet from dead stop and it just disappeared. I was entering the LIE from an on ramp off a rest stop and just continued accelerating without issue. A while later, after another brief stop, The same thing happened. This vibration happened 3 or 4 times for the duration of the ride. It's the first 30-50 feet from a stop. No other symptoms or issues. The bike handled fine, engine sounded perfect as did everything else. I've read threads on the CCT issue but this doesn't fit that sound profile. Not ticking, more like a brief rumble. Any ideas?
