Take the Haynes manual and light a bonfire with it!! Go th the Alladins cave section and download the genuine one and parts book that i scanned and Ash stored.Read, re read then read again the section about refitting cam cover, then come back and tell us what you think it says and i will agree or not. Get it wrong and you will have bent valves and broken valve guides!!!!If you go to the US site Hondaman on there has been saying for some time that newer gaskets (since removal of asbestos type materials) are thicker than original which means you need thicker O rings to get a seal.Retorque was never in a Honda manual and i never have done it.PM me direct or my email is in my profile if you want any other help.
If it is leaking from the end caps, as Bryan has said, check the alloy washers top and bottom on the end bolts. The problem with aftermarket gasket sets is the O'rings in the kit are low quality. Make sure the end brackets are on the correct side, they are market L & R. Push them back as you tighten up the end bolts. Replace the cap O'rings with a good quality O'ring and smear some red rubber grease on to make them go in easier and seal.
The part number for the O-Rings which go in the oil passage space on the cylinder head gasket is 91301-323-000 and is listed as 5 x 2.4. For some reason the 550 parts books don't show a part number but the 500 parts book does.
Get yourself a telescopic magnet, most powerful one you can find on E-Bay. Comes in very handy for fishing out dropped nuts etc Also works for fishing shims out of buckets on later bikes.
