Definitely, he MUST be one ... :-))
As Raymond is our "chief tuner", Martin maybe would fit the following title:
"chief physician".

Seams that you pulled your brake very hard ...
When you have less air in your fork and pull the brake, the bike has the
chance to nick (indive). Because of that, you have more time until the
brakes block.
Now, when you put more air in the fork, the bike doesn't nick so much, and
for that the critical point where the front wheel blocks comes earlier.
But the main problem of such systems (anti diving systems) is that if you
are not used to, you don't know what happens when you brake. I tried a BMW
R1100GS which has not a really "anti diving system", but because of it's
tele-lever, the bike doesn't nick when breaking. The first time I had to
slow down from higher speed it took some tenths of a second before I
registered that the "don't-nicking" of the bike is okay. :-))
To come back to our front fork; I think that playing around with the air is
easier to handle if you have the following additional tools:
1. main stand
2. t-tube
If you don't have these two things, it is quite difficult to adjust the
correct pressure.
But, on the other hand it is definitely exacter to regulate the dampening of
the front fork with oil - but you have to know a certain "value" where you
want your fork to be - always.
I tried a harder oil, but the result was not very liked. You noticed every
stone on the street because of hard dampening. So I'm now back to the one
Honda recommends and I'm very pleased with it. Even with sozia it is no
problem (the nicking :-)).
