I recently bought a 2020 MT-09. It is a great bike but between 50 and 65 MPH the bike has a very loud whine when under any kind of acceleration. Can someone tell me if this is normal?? The dealer says it is, but not sure i can take that to the bank. I have 2000 miles on it now. If someone could shed some light?? Someone told me to change the oil to Amsoil 10-40. Let me know some thoughts. Thanks
