Well, Sepp and myself experimented quite a bit with that many
years (12-13!) ago. The latest solution we had was connecting
the fork valves with a airpipe and attaching a small pressure
meter (1-6bar) (placed left of the speedometer).
We even drilled a small hole into the meter to fill it up with
glycerin, to prevent vibrations. All parts required have been
taken from standard air pressure equipment and the cost have
been below DM50. We even made a long pipe from the monoshock to
the front, connected another air pressure meter to it (right of
of the revmeter). We kept that construction for some years but
removed it then. At least at that time there have been balancing
pipes available from German mail order companys (Hein Guerike -
www.hein-gericke.de and Louis -
www.louis.de).
Now I use following simple procedure: Fill the fork up to aprox.
1.5 to 2 bar, use a small pressure meter which can be attached
directly to the fork and release the pressure step by step until
you reach the required value. That works very well in my case
and just by reading the meter, i can not see any difference in
pressure.
