Shock Oil and PSI

[Howie]

Good thoughts, Frankenduc.   Costco fills tires with nitrogen, you would need to supply the regulator.  Some air conditioning repair shops use nitrogen too.

Higher end paintball shops might have it too.

I brought it to costco yeterday and the guy said is too unsafe and they wont take the risk.

My regulator only goes up to 150psi. and they will not allow me near their equipment.

No other tire shop in the area is willing to let me touch their equipment either and only 2 of the 10 ive called even have N2. No motorcycle shop in NYC has N2 either. 

I havent thought about paintball shops though, ill look into that, thats a great suggestion!

How about throwing in the towel on N2 and using Argon instead?  You may be able to find a willing welding shop that likes motorcyclists.

Ive got access to both N2 and Argon (and CO2) N2 at work and argon/co2 at my brothers welding shop, but i still need that adapater thingy. and again, my regulator only goes up to 150psi. Which im not sure if thats enough.

Does argon retain water?

Well, for what it is worth, the 888 Showa N2 spec was 142 PSI.  The Ohlins for the S.P.O./S.P.5 version of the same model were 240 PSI.

Don't know about the adapter thingie.  It can be frustrating, but maybe a visit to the chem, materials science, or physics lab at school may yield results?  Perhaps you may want to change whatever valve comes on the Showa and replace it with something more user friendly?   The 888 Showa had a Shrader looking valve.

it is a schrader valve already, its because the cavity is so small if you tried to fill it up with a normal pump, you would get the pressure and immediatly loose it when you remove the filling tool.

So they created this special device

You fill the tool up with the same pressure as the bladder, then you can release the valve so no gas escape (since it equal pressure in the tool). This way you can maintain the pressure.

but im trying to figure out how to get this connected to the tank.

If your N2 supply is cheap...  I'd use a regular bicycle floor pump, connect it to the shuttle, and have a friend flood the pump inlet area with N2 as you pump it up.  Shouldn't take too long, right. 

Small trash can with cover, drill holes for the shaft of the pump, hose, N2 in, air out, seal with duct tape...  Ghetto and all that, but I'd rather do that than have 02 in the reservoir.

I understand the problem of pressure loss when filling the resi. Went through it with my modified Sachs. At a guess, what pressure do you think it has retained?

That's amazing.

a Bicycle floor pump would blow its own seals at 150psi, its only designed for 50 PSI or so. now i could do the latter, but my compressor is 60 gallons, thats a lot of tanks of N2 before i can fill that compressor up!!!

i think at 150psi, its probably only at 50psi after leak out.

SKS Rennkompressors on Amazon go for ~$45 go up to 225 PSI + or so.  I have one and use it on everything.  It is built so solid I'd walk dark streets in NYC armed only with that floor pump.  I'd even do it with $20 bills hanging out of my pockets. 

[He Man]

225 on a bicycle pump!!!  THATS MADNESS!!! If thats the case I wonder how much weight lifting i need to do to get that kinda pressure. 

Now thats a solution!!!!

[battlecry]

No weight lifting, just borrow a heavy friend to push down on the handle. 

The handle comes off, so you can make a gas chamber using PVC pipe or a disposable garbage can or even a kitchen garbage bag to surround it with N2.  No biggie to build and you can then even ride this weekend!  It will be warm(er)!

waho waho, dont get too far ahead of me, the bike is still having issues, im about to start another thread on it since i just made a  video of how its failing to start. its really bugging me out.
