@ Mitch, thanks for the feedback, I struggled a little with the pipes at 1st until I realised you can get them out with water pump pliers just turning them and rocking a little. There will be some crap that comes out with them, you need to catch this or it will end up it he head.

I've removed and refitted my cam cover gasket many times. Did yours tear when you removed it?
I too have reused cam cover gaskets on other bikes, the part I wanted to replace was the spark plug and water pump seals, I've has them leak before on a zx9r and pissed oil down the water drain hole, across my boots and tyres! Yamaha make these part of the cam cover gasket for some profit based reason.
Cleaned up the water pipe splitter that sits under the frame, lot of corrosion around the open ends, spun this off with a wire wheel in the drill, got a couple of pinholes now. Used some steelseal to coat the ends up and build up the thin metal. Then a coat of satin black.
I'm still waiting for the shims to turn up so there's not much I can do. I've coated the new gaskets with sealant and stuck them onto one side of the covers, syphoned out the expansion tank, ordered some moly grease and coolant.

Valves clearances all adjusted and rechecked, shims turned up yesterday.
Mostly in the midrange a couple at the top end as I can't measure the shims right sometimes.
Covers back on and top end water system all painted up and refitted.
Next job, dropped the exhaust off so I can clean up and paint the motor. Might have to get another water pipe o ring though as the lower pipe is fitted same as the top ones.
Feeling pretty pleased the exhaust nuts spun off ok, they are sitting in some harpic now to clean up.

Well after 7 days of flu including 3 bedridden, I managed a bit more today.
Gave the front on the engine a scrubbing with paraffin then some brake cleaner prior to thinking about painting. I'm concerned as there is still a lot of stuff in the way, oil cooler, oil filter, engine mounts. Do I just mask off as much as poss?
Took the exup valve out and greased it all up. I think it wasn't seated right before as it would not rest over the locking hole but now I've had it all out I've made it fit. This does rotate clockwise from closed doesn't it? Looking at the pulley side that is.
Gave the rest of the down pipes a real clean with harpic and emery cloth, exhaust gaskets pried out, can I reuse them? That's it for now.
When I did the front of my engine I took everything off, oil cooler, filter, pipes out of the engine, everything then just masked up the frame. Seemed the best and easiest way and it worked well
Took off the oil cooler and water pipes, bad corrosion on the oil cooler water pipes, pinholes. So out comes the chemical metal again. This bikes been run for some time with just water in there and it's taken its toll. I'm gonna have to flush it and maybe try some rad flush as well. Gave the bits a coat of paint now it's down to making the motor off and spraying it up.
Well it's done, apart from the carbs but I had to reassemble and test the oil n water tightness.
Sprayed up the motor in the frame but it was a bit cold so parts had to be done again with a heater on them. Had a couple of small leaks on the cooler pipes which were a bit of a pig to get to with the down pipes back on but it seems ok now, just running it with soft water for now to check its all sound and after a road test I'll swop it for coolant.
Put fresh coolant in it and thats as far as Ive got at the moment. Bikes all back together, not started the carbs yet, struggling a little with motivation and its bloody cold too. Thinking about a Ivans jet kit while the carbs are out - anyone selling one?
