high pitch vib noise around 3K rpm
I recently observed a high pitch noise when I am riding at approx. 3k rpm. I am not sure if it's always been there because I also recently attached a mra xcreen spoiler and made my rides with a lot less noise and wind effects. Anything below that range or above, it disappears-- just the humming of the engine. No idiot lights are on at all times. It sounds like it's coming from the somewhere near the radiator immediately below the gas tank. I check before each ride to see if anything is loose, particularly the radiator guard and the crash bars. I am inclined to bring it to the dealer soon.
Has anyone experience something like this? If so, what was it and how did you resolve it?
