Realized the other day that when the bike is in neutral ('14 f700) with the clutch out, there is a definite "rumble". Slight pressure on the clutch lever and it quiets right down. Maybe a noisy throw out bearing? Bike is new - only a little over 700 miles on it. Will be going in for the 600 mile service later this week. Will ask the dealer about it. I'm not too concerned. Just wondering if anyone else has noticed this before. The bike is new to me, so.......it might be very common. Thanks.
