Tubing: I planned to use some polyurethane tubing. The pressure rating is plenty high. I chose 4mm od and 2.5mm
id. The SMC part
# TU0425
Yellow:
(1x) yellow adapter is threaded in the handlebars. I tought a good wiring configuration would allow also
the handlebars to be rotated front to back without hurting the plumbing too much. The 90* swivel being installed directly
under the handlebars and pointing on the side allows the bars to be rotated any way you like without straining the tubes and
plumbing. SMC part # KQ2L04-M5
Blue:
(3x) Adapters 90* elbow swivel female- /to eazy connect 4mm (outside diameter) tube fitting. SMC part # KQ2LF04-M5
. One will plug into regulator. The two others are to be used on the fork cap but will not thread directly to
the fork cap. You will need the use of a threaded tube to link the female coupler to the fork cap hole.
Threaded M5 male/male adapter home made
To fabricate the threaded tube I used some 3/16 brake line tube and made the M5/0.8 thread using a dye. We have no choice
but to use threaded tube mated to a female coupler to obtain an extra long reach male coupler. Nothing availlable
on the market is long enough to reach the thread down in the pressure release hole. There is 6mm to go before the thread
starts down that pressure release hole; and there is thread from 6mm to 12mm down.
After you have finished cutting some thread on the tube, the threaded tube must then be cut to the right length.
Thread one end of the threaded tube to the female elbow fitting until it is completely seated. Leave one end threaded
and then measure 11mm of tube protruding out of the female adapter. Exactly 11mm is very important because
if there is only 2mm longer, the tube will sit on the ICS (inner chamber spring) metal washer and effectively block
the air passage. Use alot of teflon tape to ensure a tight fit. Thread into the fork cap. This procedure
will not alter the fork cap in any permanent way. When you decide to remove the system, simply put back the stock pressure
release screw and no one can tell what happened before; as opposed to most other setups...
Gray:
Plug-in Y with eyelet and solid tube male # KQ2U04-99
Black:
SMC Dual adjustment regulator. It has separate adjusters to meter in and out
flow. I think this would be nice. M5 port / 4mm part # ASD230F-M5-04
Red:
red represent the places you will need to fasten on the number plate back side. There is a red dot center
of the eyelet on the Y connector. This will need to be tied somewhere. Also I tought of using some kind of system to prevent
the tubing from being caught up. This is why the two red strips. I haven't come up with anything brighter than adhesive tape.
Black:
There are some black plugs inside the handlebars if you look carefully. These are some cork or rubber plugs
that you need to trim. They will need to make an airtight fit inside the handlebars. What is a little bit challenging is measuring
the volume before gluing the plugs. A ballpark volume would be between 120cc and 75cc. Measure the volume before gluing
the plugs. You can glue these plugs inside the handlebars using JB WELD type glue or 30 min+ epoxy.
