So I pulled off the track last night and my forks were at half mass...No oil coming out of the seals (i dont know if that even happens) and the forks were about 3-4" lower in the sag than when I started my session. They feel empty too...What may or may not have happened here? Just air them back up or?

Thanks!

What was the air pressure on each leg?

I was running 31.5 (it was at 36 first moto bc of how hot it was and it was wayyyy harsh) 31.5 felt better but then 3rd session out it started feeling nosedown and springy which is when I realized it was through the stroke pretty far :/

Did you check both forks after said issue to see if there was an air loss?

I'll have more on that after work today...I just loaded up since I was done riding anyways haha

Are there any other signs around the fork seals that would lead me to believe they are "blow" or whatever happens with air forks? Sometimes does the air jus leak out somehow?

Typically the air leak would come from the seal, but I have seen an o-ring fail one time in the compression adjuster housing which caused a leak.

ok Sad

Any suggestions as to which fork valves to use to make it easier to reach em and air them up or down?

My 13 KX had a blown fork seal, and would leak, but also leak oil. The front would run way down and would loose pressure fast.

Luckily the 13 KYB forks are easy to work with and you dont have to worry about holding the spring down. Put some new oil in there, and new seals and she'll be good to go!
