Hello! The rear suspension is fairly squishy on my Interceptor. More play than necessary. Worse with a passenger. I've set the dial to between the battery and the tank. Is there anything else to check? The Clymer manual's no help here. Thanks!
What air pressure are you running? BTW, consider buying an aftermarket shock. I have a Hagon. The stock shock sucks.
This is a really common problem with the early VF's. Go to my site and click on the 'Rear Shock Solution' for info on what I've done to adapt later model Showa shocks to the early VF's. This has been super popular (I've been backed up with these for a couple of months now) which just shows you how wide spread a problem this is.
