| the only way to go about it IMHO is to experiment. try one adjustment at a time take it out on your fav bit of road see how it feels. work on one thing at a time, find whats best make a note of it and then try your other adjustments in the same fashion. you'll soon get an idea of whats doing what to your handeling.
slightly worn head bearing? i assume there isn't any actual movement?
also make sure your tyre pressures are correct, some of those in the fuel station forcourts are that far out that they are not worth using
it took me ages to get mine how i like it
good luck |
