| Re: Noisy in 5th gear !!!
Cut & paste answer. Very, very common complaint.
Harley six speeds have helical gears, except for first & fifth.
Fifth so as to enable the electronic speedo.
That & very lax build spec can lead to a noisy gearbox.
Some are whisper quiet, some sound like a Massey Ferguson.
A good quality Full Synthetic Gear Oil will help a great deal.
We have had excellent results with Redline & Bel-Ray.
It won`t go away, but it will quiet it down.
