For mine, I gave them a gentle, respectable break-in and at 6000 went to a top quality full synthetic (Mobil 1 20W-50). After that all I did was change the oil and oil filter every 6000 miles, at which time I also checked/adjusted the valves. Cleaned the air filter as needed (use Twin Air and NoToil filters with NoToil oil). Stock doo.
Front side of doo hickey after 130,000+ miles
Back side of doo hickey after 130,000+ miles
But I did loose the spring which allowed enough slack on the balancing chain to let it eat into the cases
This also caused serious hooking of the balancer chain sprocket on the crankshaft, which with my anal approach to rebuilds makes this engine toast, and why I got a used engine to rebuild.
