Not I. Recently went to a 17 tooth on the speedie. I cannot say I note any difference in relative noise levels or extrafricttritious auditory concerns.

Yes at first. You have to be more aggressive with the gas and the clutch release, its the additional load from moving up a tooth. Mine did it at first and found it was my driving habits rather than the bike.
I try to aggravate one person a day. Today may be your day.
