You need to source
 
1. - a nitrogen bottle
2. - a 50 bar pressure regulator
3. - 4 ft. of high pressure hose
4. - a suitable schrader valve adapter
 
I did: 
 <= /div>
1. -= visit my brother. I knew he had a nitrogen bottle, so I just asked him if = I could borrow it for a puff. It has been a while since he asked = for the bottle, so I now consider it permanently sourced

2. - search my brothers place for a suitable regulato= r but failed, so I actually had to pay for one. This is NOT your off-t= he-shelf welding gas regulator; it is a high pressure regulator that is pro= duced in much smaller numbers and overpriced accordingly. I believe I paid some $400 or thereabouts for mine. &%=A4= # !!!
 <= /div>
3.&n= bsp;- find a piece of 30 bar rated hose somewhere
 <= /div>
4. -=  buy the smallest push-on type adapter obtainable and modifiied i= t on a belt sander, so it became even smaller (i have only 3/4" betwee= n my air filter box and NG schrader valve). Also replaced the rubber gasket inside the adapter; it is way too soft for these kinds o= f pressures. A nylon washer works.

LNC2= nose oleo:

Open= nitrogen bottle (225 bar or so....)
Turn=  regulator up to 25 bar

Give= it a quick puff of nitrogen
Chec= k for 3" travel
The = strut is probably slightly over inflated, so VERY carefully let a little ni= trogen out. It is hard to hit the right spot, so you might have to do it ov= er a couple of times.

Ongs= Debongers:
 <= /div>

Open nitrogen bottle (still 225 bar or so....)=
Turn regulator up to 25 bar
Nitrogize!
Adjust height by carefully letting out a little nitro= gen
