Synthetic oil

I am planning to switch oil in my 2004 Sportster to synthetic.  Does ALL the petroleum oil have to removed and if so, how does one get all the oil out.

RE: Synthetic oil

1.  No.  Just do a regular oil and filter change.

( 2.  Complete disassembly. )

RE: Synthetic oil

Thanks for the advice.  

Think I'll do a second oil change after 50 or so miles for no particular scientific reason.

I though dimantle was the way, but hope does spring eternal.  

RE: Synthetic oil

It's not like changing oils in an A/C system when you change refrigerant; the engine oils are miscible and compatible.
