Think the steeper head angle is better used with the longer swingarm and different shock linkages. If you do change the head angle, it will slap a bit, even with the steering damper. It will also feel like it is tucking in on slow corners on a neutral throttle
I assume the standard settings are detailed in the manual - unfortunately I haven't got one (its on order). I do have a Haynes however, does anyone know if the standard settings listed in there are correct?
For what it's worth i set up my R6 and ZX7R per the PB guides with wonderful results on road and track. I'd personally gice it a go and see how you get on if you fancy fettling one afternoon.
I'd have a ride on standard settings first though as a bench mark - you can always return it to standard again.
Things like wear&tear, rider weight, tyres etc will all make a difference to some extent. And a good set of tyres which you are confident with are worth a thousand times more than a fancy suspension set up IMHO.
