I had that on my 750F. I wan't sure what it was but when I experienced it the valves had just been adjusted by a reputable mechanic. I couldn't say that it was definately a valve chatter but it was annoying. I think when I questioned others about it I probably identified it as a vibration but it was more of a chatter and it only occured between 4500 and 5000 rpm. Last fall I changed the chain and sprockets. the sprockets changed from the original 46/18 to 42/17. I have not noticied the chatter since. I probably just got used to it. If I am going out for an extended ride (100 or more miles) I have a tendancy to wear earplugs. I think it helps me hear the engine better. With earplugs the chatter is totally non-existent. Just my experience.
