Ya. mine does it. All the six speeds have a whine in 5th gear. That is because you will spend a good amount of time in 5th and as such they made it a straight cut gear instead of the more quiet hellicul cut. I look at it like this; "if a design engineer thinks it ought to be straight cut, then who am I to disagree with him". Besides, that is how I tell when I am cruising in 5th gear. Mine is not to the point where it distracts me, once I realized why they did it. You are after all is said and done, sitting on an air cooled engine with a manual transmission. Not like your car, you know.
