First, I have to say how pleased I am to have discovered this forum. This is my first post although I have been following conversation for sometime. I drive a 2002 zl800efi ss and I would like your comments on two questions. First- I've read that some people have had some shock failure (electronic ) and when this happens the suspension behaves like a typical ZL suspension with Ride FX shocks. Is there any measurable method of determining if the SS suspension is doing what it was designed to do or are you required to remember how it was initially and make comparison? Second- Has anyone thought about or done a conversion from the 121 inch track to 136 inch track with the SS suspension? How do you think this change might affect how the suspension works? Thanks for your comments.
