2010 limited harmonics
I have a 2010 limited that has noise in the primary case area. I have taken it to the dealer and they find nothing out of the ordinary sounds. Riding it today and I notice that its a harmonic sound that increases or decreases with speed only, not RPM. at 45-50 mph I pull in the clutch and let the RPM come to idle and you can hear the harmonic noise in the primary and it doesnt matter what gear or RPM the engine is turning...I am thinking its the compensator and not sure if I should take it to different dealer, warranty runs out end of Feb. Looking for suggestions...

if compensator, it would be rpm dependent--- the compensator turns with the motor.
this also rules put primary chain, tensioner and clutch basket, all of which move dependent on the rpm of the motor, not the road speed.
the noise may be generated in the tranny or front pulley.
try a different tranny lube
maybe clutch rod... ?

I started this thread quite a while back - is this what you are experiencing. Sound has gone now, not sure what it was but it wasn't tires in my case

Agree totally, which is what I experienced and referenced in the thread, i.e. my issue was also speed dependent and seemed to be roughly in line with each rev of the wheel (not engine)

I will try new oil, dealer put on a new drive belt and they used their oil ( I run Ams). I will check out the tires although I only have 4K on them. I know noises travel but I would have bet money it was in the primary...thanks, I will investigate all you have suggested.
