I have a 2012 VV ABS with 300 mi. on it. At 30-32mph (and only at 30-32mph) there is a high pitched whine from the rear. It is louder than the exhaust and is embarrassing. Any ideas are appreciated.
My belt whine sounded like a low note on a brass horn around 15 to 20 mph.
Belt whine would still be my first guess.
Those things come super tight from the factory.
It probably wont cause any issues, but I would tell the service tech about the sound at the 600 mile service and ask about belt tension.
I read your other posts too.
If there is a loss of power; that would concern me a lot! I would call the dealer. Can you tell us what your coolant gauge reads?
I had a tapping sound at idle when the engine was warm. I think changing to synthetic at 2k miles cured my issue. (I have done other mods too though)
I would have the dealership perform the 600 mile service; this will strengthen your side in warranty claims.
After the 600 mile service, I would add 2 ounces of seafoam to the oil; ride 100 miles, then switch to (motorcycle specific
) synthetic oil, using a K&N oil filter.
I would also do this
oil change MYSELF.
I would flush the coolant and replace with a 70/30 water to coolant ratio and use a couple of ounces of water wetter.
Getting more free flowing pipes and a fuel controller (PCV 5) helped to cure the EPA lean condition and let my engine run cooler too.
I will say that my Voyager had some operating temperature issues when I bought it.
A small amount of money and time on the oil change made a significant difference.
A little more money on pipes and the PCV 5; made the bike pure joy.
