View source for 100% N2 vs. 78% N2

Air is 78% Nitrogen, 21% Oxygen, and 0.9% Argon. The balance is a collection of many other gasses. You do not want to use air in suspension systems or track tires.

===Why pure Nitrogen===
Nitrogen is simply better than air in all respects when dealing with tires and shocks. Since N2 cannot hold water vapor like air can, the pressure change due to heat is very consistant.

Also, Nitrogen molecules are larger than Oxygen molecules. Less pressure is able to leak from the system due to this geometry.

===Final Gauge===
Longacre Racing has recently released a nice digital shock inflator. [http://www.longacreracing.com/catalog/item.asp?id=1036&catid=19 PN# 50472] Longacre is a pretty nice firm making some quality products.<br>

A special head on the inflator allows you to fill the shock, but not loose any pressure when the inflator is removed.<br>

This gauge will read fairly accurately to 0.5 psi increments.<br>

===Valve Connection===

A high pressure inflating connector can be found online at such dealers as US Industiral tool. PN# TP506 $48.00

===Valve Extention===
Often, you will need to extend the shrader valve to get proper access to it. [http://www.motionpro.com/motorcycle/tools/nitrogen_shock_gauge_and_filler Motion Pro] sells extenders for pretty cheap (PN # 08-0132, $2.95 ea.)<br>
