Webby, the Strat/Roadliners have hydraulic lifters so they do not require adjustment.
The owners manual officially recommends a 'check and adjust if necessary' at 16,000 miles.
The service manual has the following note: The valve clearance is automatically adjusted by the hydraulic valve lifter. However, there are times when the valve clearance needs to be adjusted manually. If this is the case, adjust the clearance of the two maladjusted or worn valves using the adjusting screw on the rocker arm.
I'd assume that the manual for any hydraulic lifter equipped engine would read similarly.
So, as a practical answer to your question, No, the valves on a Stratoliner do not typically require adjustment, that is, of course unless they need to be adjusted.
