I became accustomed to that noise having owned the 102cu.in. Warrior before the Strato.
You can bring it in to check it out just for peace of mind, but you may hear back that it is a normal noise during start ups, especially after sitting unused for a few days. if you shut it off and put it away and one of the valves is in an open position, the oil associated with that valve will drain into the sump area and air will get into the valve lifter area. It takes a few minutes to replace all the air with oil and you will hear lifter noise during that time. I can't hear the noise to compare it to what I hear every morning so if you feel it is excessive, take a ride to see your dealer and inquire.
