Default Valve adjust on 90 flhtcu

This is my first Harley. Can anyone give me info on the intervals of adjusting the valves on a 1990 EVO 80 and what is involved in doing it myself?. I'm very mechanically inclined on the musclecar era of cars but just like anything, this is new to me so any advice/info is greatly appreciated.

If it has stock pushrods you don't/ can't adjust the valves.

My manual for 90 flt/fxr doesn't list any interval for adjustment. Hydraulic lifters do not require adjustment.

Its eazy to tell what the push rods are by pulling of the covers on one and see if it has threads with a lock nut. Did you get any info about the bike , Most people with the evo do cam up grades.

Unless the bike has had solid lifters put in by a previous owner, the lifters are hydraulic, and require no adjustment

I guess we could throw out there that if your valve train is noisy, you may have a bad lifter, but seldom, for the most part that they fail.
