AER 48 Fork woes!
I had my 2017 450sxf forks collapse on my second snowbike ride.
My local suspension guy, Kreft Suspension, took my air side apart, and replaced the stock x-ring with a traditional O ring and it seems to be doing the trick.
I was at my dealer today, and they mentioned that another customer pulled their fork apart to find the x-ring installed upside down. (theirs had collapsed as well) Not sure of their results after flipping things over.
Riding tomorrow in some cold temps. We shall see.

I have had several failures . I modded the fork so now I have a simple bleed screw on the fork tube to let the air out so they can be simply re filled, No taking the fork apart every time. I suspect WP will incorporate this into the next version, If they don't then they need a new design engineer.

I can e mail. having trouble posting, you take off the blue nut on the end of the rod, the one we use to bleed off the pressure and drill a tiny weep hole through the middle. Then remove the blue nut from the bottom of the fork tube and drill and tap for a external bleed screw, it needs to have a recess lip so the o ring will drop into that space, then use a allen head screw with the o ring on it.when assembling that bottom nut needs to have Teflon tape to seal the rod end threads so its sealed. now when forks fail simply loosen the new bleed screw at bottom of fork and pump the high pressure side back up. can fix on the trail in minutes if they fail.

Thanks!
Hopefully this will help a bunch of people!
I'll look mine over, but probably just ride until I stick and then send in for the spring conversion.

We are buying all of the forks we can in the used market and teaming up with RG3 to set them up with snow bike specific valving and springs to rider weight and system set up. Give us a call today. We will take about 20 min. to consult with you on your setup and riding style. Then we can have a set built for you ASAP. $900-1200 depending what forks you choose. This is a full set of replacement forks. Keep your AER forks for the dirt and enjoy a custom snow set up built just for you and your machine.
Thank you for your snow MX business!!!

My forks failed again on the mountain, I was able to open the bleed screw I added and fork raised back to normal height, re pump and back up and riding in a few minutes, then hours later they failed again. I have a set of new open chamber with .64 springs and a set of AER spring conversion forks with re valve to run and compare, The air spring will always be a failure in the old temps.
