I have an issue with the air ride system on my 2006 K9 Custom, it airs up just fine, but not by using any buttons on the hand controls, but by a toggle switch mounted on the left side panel, outside of the battery thingy. The only thing is; after riding a while, I shut off the bike, and in a matter of time......an hour or so, the suspension seems to just "bleed out" and it's back down again; I don't know if this is an automatic function or not.
The service guy told me, "This a safety function of the air ride suspension; after you start the bike, flip the toggle switch, and air up the suspension up to about 90lbs psi, then go riding; while the engine is running, the system will stay aired up until you turn off the engine, the system will then bleed out back to the stops to avoid damage to the shocks staying aired up"....
