On my 2015 GSX SE 1200, I noticed noise last year when mid range throttle where it sounded like parts were rattling around in the drive train with moderate acceleration. The dealer did the year end thing and said all looked good. I heard the same thing this year with 1000 miles on it. And it comes and goes. I've seen a lot of talk about clutch noise and not sure that is what I am hearing or what everyone is referring to as nuisance clutch noise. Seems like it happens more when things get hot. Anyone else familiar with this particular noise?
