I am expecting delivery this afternoon on my SERG. I know these come with synthetic oil. I don't really understand that considering most people will tell you to break an engine in first before installing synthetic oil. Also many suggest changing the oil at 100 miles. Since the bikes come with synthetic should a change be done at 100 miles or so or just wait til 1000? T.
Synthetic oil doesn't adversely affect the break-in of the engine, no matter what all the wive's tales say. If it did, do you really think Porsche, BMW, Corvette, etc., etc. would use synthetic as initial fill in their engines? In other words, don't worry about it, it's a non-issue.
As for the first change, there is no compelling reason to change it before the 1000 mile service. However, if it makes you feel better you could change it at 500 instead of 1000. I wouldn't do both, however, since it would just be a waste of money and resources.
