It appears that S&S recommend an oil change after 300 miles to get rid of the swarf that may be in the engine, then another one around the 1000 miles figure, after that probably every 3000. Excessive maybe, but for the cost of the oil and a half an hours work, probably worth doing, especially if one plans to keep the car for a while.
Talked to a number of bikers with S&S power plants. The beginning is important, as with any engine. Most are going with 5,000 mile intervals as the synthetic oil holds up really well. With the added capacity of the Morgan, 6 liters vs 4 liters, we should be doing very nice indeed. If I was living in the Southwestern united States with blistering temps I may shorten that to 3,000 miles. I remember the first oil change and removing the plug at the bottom of the block. There is a magnet there to catch any metallic debris and it was very clean. Most impressive.
I completely agree what with all the other problems that may, and have, crept up the oil change dialog is a bit moot. It's a good engine.
Every thing else is the tricky part...
