Alimacdee2, got my cylinders and head skimmed at UK Recon, 3 Salkeld St, Glasgow G5 8HE, tel: 0141 429 7338. They did a good job and wasn't very expensive.
If you want the gasket, PM me with your address mate.

Finally got the bike back together, head skimmed up nice, used a Honda base gasket this time, ujsed a Vesrah Head gasket with matching o-rings off ebay from nurse Julie I believe, and thanks for the correct o-rings for the head and base gasket. And thanks to Archmill for his offer and sending the gasket much appreciated.....After two run outs its looking oil tight again, and running really well. Very happy.
Now to rebuild my wheels...

It’s not fine to have to take the engine out of rebuilt bike that has been painted etc. at least there are no seized bolts and screws to deal with. I had to take the engine out of mine again after just 200 miles. Had to split engine and get into the gearbox after a problem with it jumping out of 5th gear. Great news you got your oil leak sorted. Just need some descent weather now!

Good work and nice feeling when you've corrected something with a thought through solution.
They aren't a complex engine, but with careful detail attention needed to ensure reliable running one of the largest parts.
Hopefully all set for getting out as better weather comes

thanks for those comments, must admit relieved to see it work out originally as planned! and looking forward to the warmer weather
now completed the rear wheel rebuild with a DS spoke kit, a bit of surface corrosion on the original front rim, only lasted 55 years with a rechrome, prefer to keep original parts but looks like I need a new rim and spokes. this seems to good a deal on ebay? or its DS again?

Better to buy a DID rim from David Silver and stainless spokes from CWC. That one advertised on Ebay is a Takasako.
I'm pleased the engine is no longer incontinent 😁😁

Ha funny you mention that this bikes given me the urge!
stainless would be nice for the extra cost, always liked the idea there’s more give in flexible mild steel spokes, did have a look at your eBay shop for parts btw, a see DS has 2 front DID rims, I’ll maybe give them a ring tomorrow.

I think that every 750 I have owned eventually had rusty front wheel spokes, so when I rebuilt my F1 wheels it was stainless spokes all the way, never looked back since.
