I adjust the hard way. With the car put together and the servo on I try to turn the wheels if I can turn them easily then its too loose, if I cant turn them then its too tight. I like it to where they are difficult to turn bur so the saver still works. Also you can watch the saver work using this method. The last test is on the track - If the steering feels loose then I need to tighten up the saver. It is a feel thing some drivers like more servo saver action than others. The worst thing I have had happen with the saver too tight is break the plastic saver or blow a top bearing in a JR9100T. The servo still worked it just had a lot of slop.
