What air pressure in Fox airshocks

[Lozza]

Specific heat is the amount of heat(in kJ) required to change temperature of one kilogram of a substance by one degree. Specific heat may be measured in kJ/kg K or Btu/lboF

Hydrogen comes out on top.
Air   0.718
Nitrogen   0.743
CO2          0.655
Helium      3.15
Hydrogen   10.16

Helium is not so silly as it sounds and looks worth a try, don't think hydrogen comes in a bottle.

Interesting stuff,

This straight from the manual in front of me.

CR250 78-79 Lever ratio is 1.8. The bikes weight is 215lbs ready to race, me with my gear on is 170lbs or around 80kgs Air pressures should be bottom 128psi and top 85psi and always fill bottom first with shocks fully extended. They also recommend to over inflate by a little and reduce with a good gauge. Then ride bike for one to two minutes then recheck they will be down 15-20 percent if they have been rebuilt or deflated completely.

What the other guys are saying is spot on, it depends on the lever ratio of your bike your bikes and your weight as well.

Tell us what bike it is and if its in the manual l can give you a starting point.
