Been a mechanic for 30 years just not on bikes. Need a nudge in the right direction. Clearances, special marks to look for. Simple things like that.

If they are hydraulic, they don't need adjusting, if they are solids, they need adjusted about every 3000 miles. Most likely you have a bent pushrod, if it just started making noise. To check them, raise the valve tubes, and spin the pushrods to check for runout, Crane makes replacements that are adjustable, and you don't have to pull the heads to install them, they are called Timesavers ( for obvious reasons.)

If the engine is stock there is no adjustment on the valves, they have hydraulic lifters. If the engine has been modified and has adjustable pushrods you turn the engine over till the lifter you are adjusting is on cam baseline, loosen the pushrod, re-tighten the pushrod till it has zero lash then give it another turn or turn and a half to to set the preload and tighten the lock nut.

k this is a hydraulic lifter bike and you do not need to adjust valves in a harley. if you have adjustable harley pushrods then you need to adjust them about 2 1/2 turns at zero lash. it the push rods are one piece you cannot adjust them. 95 inch or 88 inch or whatever inch. if they are not harley adjustable push rods you need to find the thread pitch and adjust accordingly. if it just started making noise and you have non adjustables in it.... you have other issues. take it to your dealer.

no adjustment necessary for stock hydraulic lifters.
the question that comes to my mind is...why do you think they need adjusting?
harley motors make a fair amount of noise in their valve train, not like a car at all.
Did you get the motor in pieces?
The push rods are labeled with color bands which indicate their orientation (up / down and front / back), you need a manual or some experience to know where they go.
I don't know off hand which ones go where or in what orientation.

Hydraulic lifters, no adjustment needed, unless aftermarket cams and adjustable push rods have been installed.
It's not uncommon for new Harley owners to mistake the normal rocker box noise as a mis- adjustment . Tap, tap, tap, get used to it.

if you've got solid lifters you set them at 0 lash cold that is no slack at all but you can still turn your pushrod with your thumb & finger but i've never seen a twin cam without hydraulics maybe you should get some body else to listen to it before you do anything.

a friend had to have the cams adjusted after about 50,000 miles on an 03... engine sounded like it was popping popcorn... it was a dealer maintenance thing... don't know what it would cost.. he had the extended warrenty.

If it's still stock there is no reason to adjust, all is done at the pushrod.
