THe oil part is easy....any synthetic is good for the motor, dont believe the hype about "burning" up your clutch.
Usually when checking valved you want to bring that cylinder your on to TDC of the Compression stroke, that means ALL valves are closed and you are able to check the tolerances, that the book should have, if not GET A FACTORY MANUAL.
I do not know anything about a starter valve synchro...dotn know what that is to be honest with you. I have done valve adjustment on my 600RR and many of my cars. Good luck alot of guys here are VERY mechanically inclined
