You can get a regulator, hose and lock= ing schrader valve on eBay for under $200.  Just search high pressure n= itrogen regulator kit

"And what pressure nitrogen goes into the oleo too? How is that done?"
 
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: 
 
1. - v= isit my brother. I knew he had a nitrogen bottle, so I just asked him if I c= ould borrow it for a puff. It has been a while since he asked for t= he bottle, so I now consider it permanently sourced

2. - search my brothers place for a suitable regulator= but failed, so I actually had to pay for one. This is NOT your off-the= -shelf welding gas regulator; it is a high pressure regulator that is produc= ed in much smaller numbers and overpriced accordingly. I believe I paid some $400 or thereabouts for mine. &%=C2=A4= # !!!
 
3.&nb= sp;- find a piece of 30 bar rated hose somewhere
 
4. -&= nbsp;buy the smallest push-on type adapter obtainable and modifiied it o= n a belt sander, so it became even smaller (i have only 3/4" between my air f= ilter box and NG schrader valve). Also replaced the rubber gasket inside the adapter; it is way too soft for these kinds of= pressures. A nylon washer works.
 
I am n= ow a certified nitrogizer. I=C2=B4ll nitrogize anything. The procedures are:=
 
LNC2 n= ose oleo:
 
Set r= egulator to lowest setting possible
Open n= itrogen bottle (225 bar or so....)
Turn&= nbsp;regulator up to 25 bar
Have n= ose wheel off the ground or things will get messy
=
Give i= t a quick puff of nitrogen
Check= for 3" travel
The s= trut is probably slightly over inflated, so VERY carefully let a little nitr= ogen out. It is hard to hit the right spot, so you might have to do it over a= couple of times.
 
Ongs D= ebongers:
 
Set regulator to lowest setting possible
Open nitrogen bottle (still 225 bar or so....)<= /div>
Turn regulator up to 25 bar
Nitrogize!
Adjust height by carefully letting out a little nitrog= en
The mains need not be off the ground; the Debongers do= not leak oil when inflated
