Losing air in front forks..no visible leaks

[Clevelandpat]

My 2001 Road King trike loses fork air in a few hours and cannot find visible leaks. Should rebuild forks or change to all spring forks. I like the ride with air as it raises the front about 1.5 and levels bike nice. Thanks for any help.

Check the valve on the input. Sometimes they are a bit loose ,or just become bad. Easy first check & not expensive to change. You can either change the whole valve or just the just the insert.
