KTM WP Shock Nitrogen Filling Options

[kenferguson]

Air is 79% Nitrogen (78%N + 1% Argon). "dry" Nitrogen(N2) and "dry" Air(low dew point) are often close enough to be used interchangeably. Expansion rates are also similar enough. "dry" Air- (low dew point/ super dry) is like you get at a SCUBA diving shop, it's air that has been cooled to ambient or lower temp before being filtered for water. Water/vapor is the biggest problem, with enough heat water can flash off into steam and spike pressures. Water + air can support corrosion. Important: Not all Nitrogen is "dry", welding tank type is usually cryo separated and pure(dry). Tire shops/commercial often produce N2 on-site using PSA separators. PSA's are basically a filter system for air that removes O2, problem is that many/most "tire" systems have crappy filters and they filter the air hot (so- HI dew point or wet N2). Another concern is "pressure loss", O2 is smaller than N2 so any pressure loss would be slightly higher with Air. Now Back to the Real World-- I mostly use "dry" air. I made an inline filter filled with desiccant to dry/filter any questionable air I use(cost-$5). Some use in-line driers like those for spray painting. SO.... pure N2 is best, but expensive and a pain to deal with. Quality "dry" Air is adequate for most, cheap, easy to deal with. Coin operated gas station air pumps are the worse! They pump a lot of water/vapor, which is why I always have my in-line filter with me "just in case". BTW in my filter I mostly use Activated Alumina beads- cheap, stable ceramic (won't dissolve), re-usable by baking the loose beads at 400 F to dry out. About me: Learned about Hi pressure gas systems in the Navy, later owned 2 dive shops and a compressor biz. semi-retired now and love to tinker with ridiculously over powered air-guns/cannons.

Good video. Very informative and answered a lot of my questions. Thank you.

[jspotterf]

Thanks for the options discussion. Nicely done.

[tkstroke]

You did a great job explaining all the different options, nicely done video. Thanks

[garrettschlegel]

Great video....not a big fan of the self sealing bolt, but was curious how the Race Tech charging tool work and you answered my question. It's not cheap, but at least I know the charge will hold. Thanks again

[MichaelLee]

Great video and thanks for the explanation... Have a good day... Cheers

[MdubFrederson]

This is great, thanks. That said, the manual makes this look like an impossibly difficult task. Do you need to check the internal piston location every time? They have an insane machine for purging the shock... does that need to be used?

[Poke-America]

Have you had any failures when using the SELF-SEALING
NITROGEN CHARGING BOLT from Racetech? It seems there are many complaints on various forums of the bolt failing to hold pressure.

Without taking into consideration the effort to install a Schrader valve, would you recommend the Racetech bolt or Schrader Valve option.

Thanks for making this video, very helpful

Great Video man, BTW, how do we know how much of Total Nitrogen is filled in the shock other than how many PSI?

[SpicyCarModz]

Question for ya.
I've got some shocks, and after removing the plug at the bottom of the resevoir, theres no shrader valve at all. It looks like it has some kind of round rubber stopper at the bottom of the hole, but no visible le Mark's on it
Not sure what to do about filling it now.

Great video man, can you do some videos of how to safely use the nitrogen to fill a shock with the needle set up? I'm planning on servicing my Fox MTB shock, Ive done rockshox shocks many times but they use air and a schrader valve but I'm new to Nitro.

[Brian-thqn]

Great Video, Where did you buy the shock vaccum bleed tool in the background?

[Twostrokealec]

How long does it take to charge a shock? I have a valve on mine and these two guys told me they'd have it done tomorrow I think there bull shitting me

[josevelez]

Do you have any Idea who can make a custom nitrogen bottle for my shock ? Is a 2014 150xc shock, but a need Bladder type bottle between 105 to 110mm long.

[DylanDavidVindasLopez]

hello!! i have an old fox vanilla RX bike shock that i need to fill, but i only have acces to a shock pump, im going to fill it with regular air and call ir a day, but i dont know how to attach the needle to the pump, and i dont have acces to the racetech tool, anyting i can do?

[miguelpaneda]

can i refill it with ordinary air using tire inflator?

[Youtuberngajelas]

Hai mr dezert. Does releasing some of the nitrogen out of my wp semiactive shocks on my 2017 ktm 1290sa s will make my shocks softer and make a more comfortable ride? Thx

[polishcow]

Hello sir. Where can i fine to order the shock bleeder

[philisaac]

There is never an end to special tool I need to buy

[tiagomonteiro]

Hi, I have one of those pumps for air suspensions. I use it for the bladder type ktm suspensions (TE 250 2012).
What it instead of using nitrogen, I would go and use this pump. How much psi or bar does that take?
