The instructions that came with the pistons and sleeves for my H said to put oil in it and start it a idle. Once it is running advance the speed gradually to 1500 rpm and check for oil pressure, leaks, odd noises, etc. Run it at 3/4 throttle until normal operating temperature is reached. It warns against operating the engine at low idle. Check the carb adjustment and timing. There is also a little chart that says after it warms up with no load, to run it 1/2 hour at rated rpm and 1/4 load, 1/2 hour with 1/2 load, 1/2 hour at 3/4 load, and 1 hour at full load. How you do that without a dyno, I am not sure. The instructions say to retorque the head after the 1 hour, full load run. And to avoid over-loads, excessive idling and no-load operation for the first 100 hours. If you have a new cam or had the old cam reground, you should not let it idle for the first twenty minutes or so. I changed the oil after about 2 hours.
