Suspension not filling up...??? Tag pressure not going up???

[t3brian]

Thank You everybody for your suggestions......

A combination of filling the suspension a few times after a short
around the block drive did the trick!!!!!!

However is this a sign of something on its way to a failure???

or... is it simply a sign of older parts that every once in awhile
need a little kick start to get going???

the bird did 'rest' for 6 months since it's last venture....

but she is up and ready to go now...

again thank you all for your suggestions...

something is leaking badly during the air bag fill.
