Silver Wing Shifting into Overdrive

I have a 2003 Silver Wing 600. When I excellerate to around 55 to 60 mph my Wing shifts down dropping RPMS down about 400rpms. It actually does this twice dropping about 800 RPMS totally. Like having 2 over drives in the transmission system. It cruises nicely at about 4900 RPMS at 60 mph. I have asked a couple of dealers about this and they don't know what I'm talking about, not surprising. Does anyone know how this works and where? In the CVT? The clutch?

Hi.
I think there is something wrong in your CVT. It`s sticking somewhere. There´s not overdrive in the CVT. You must open the system, clear it up or change new parts.

The CVT appears to be doing what it's supposed to do. At higher speeds, on flat terrain, lower revolutions needed. Better highway mileage results.

Your Swing is working fine.

Hi.

If there is a stroke in the acceleration, there is somehing wrong with the front or rear of the variator.
Spins must be evenly lovered.

I understand the Dibber to mean this.

CVT, that seems to say it all, it should feel seamless up or down in speed a 'shift ' point to me would indicate a sticking somewhere. The variance in tach readings will be different at a given speed depending on load. I see that in our CVT auto transmission.

I finally resolved my CVT issue. After cleaning and spraying Teflon on the ramps, cleaning the CVT, buying a new ramp. I replaced the Dr Pulley sliders with a set of oringinal Honda rollers and now the CVT is working as it should and I’m really enjoying this scooter.

Glad you figured it out! Here's to many more miles of riding.

Gee, stock parts work well!! I am now on 10th new maxiscooter, never modify drive line---always use OEM belts and change at makers recommended intervals. Only one broken belt in over 400,000 miles.....Helix,, carried spare belt and they were easy to change without removing pulleys/pulley or special tools---just remove cover and squeeze rear clutch. Nice design!
