There 'posta cut down on the "noise" the fins make as the vibrate. I don't think it gonna make much difference on a 4 stroke, inline 4. All my ring-a-dings had em but I could tell no difference in noise when thay all eventually fell out.
They coulda been one of those EPA things, ya know, 45db at 15 ft at 45mph or some other silly requirement those guys made Yamaha come up with.When a 10 isn't enough, get a 11. 80g HardbaggerComment
