Low interest Jap market import. Honda -can- be very helpful if you are
polite and persistent. David Silver are a goldmine for Honda bits. Also try
ringing/emailing[1] companies like D&K, Bonanza etc who deal in/ used to
deal in grey imports.

help, possibly someone who can fabricate from a template. I have tried
the usual suppliers David Silver etc without success. I believe this
model was made only for the Japanese domestic market, and was imported
into UK in the grey area. I like the bike it has a smaller version of
the old Honda CBX 750 engine.

Unless you are used to dealing with engines like yours, I wouldn't recommend
dismantling it. They are a wonder of modern precision engineering, and a
thing of beauty. IMHO, they are close to being designed as a unit, not a
repair item if something major needs dismantling.
Anyways. Check the following before proceeding.
Valve clearances
Fractured valve spring
Compression dry
Compression wet
Leakdown ( if possible )
Carb balance
As for custom gaskets, look in the classified sections of classic car + bike
mags. You'll usually find a gasket maker in there.
