chect to see if rear shock holds pressure

[tricky1961]

hi my son just got a new 125 n i checked the rear shockie pressuer of the nitrogen but its empty the shaft has no rust n the seal isnt leaking can i pump a few psi of air in it to see if it holds b4 i get it regassed as they want over $35 to put nitrogen in it n if its going to leak id rather put that money to a new shock im going to change the valve core just to make sure thats ok as it had no valve cap on it n may b it got some crap in it n leaked at some stage wats your thoughts on this im only going to put about 30 psi n check it over a couple days cheers richy

just have to be careful on how quick you deliver the air to the shock, to quickly will blow the seals out...

that price to fill it is very expensive, is it from a bike shop ?

at those rates to have your car tyre done would be about $800 each.

putting air in the shock could introduce water/moisture inside the shock and cause problems later.

yea I got a FILTER DRYER on my air line as I do a lot of spray painting so that eliminates the moisture side n I was only going to set the pressure at about 15 psi till I put about 20-30 psi in it I have since been put on to another place that wiil do the nitrogen refill for about $20 n its a bike shop the other place was a tyre place n if it dose hold the air I was going to let it back out straight away its only 4 a pressure test
