I concur with Redfish-Joe...are the 1st valve adjustment, after the engine is "broken in" the actual valve adjustment it should be able to tolerate an extended schedule to 20,000 IMHO.
On my sportbike air cooled, 4 cylinder Kat which has more wear and tear, 13,000 RPM redline, (16 valves), stressed lubricating oil doing "triple" duty, it required 3 shims (2 thicker, 1 thinner) in 30,000 miles. Compared to the V-rod, 10,000 miles does seem "rather" short for a torquey, modest RPM, water cooled V-twin, with separated engine oiling from tranny and primary system.
