Thanks for that :)
I went and had a look, and found something that fitted so I could check the thread size. Interestingly...the oil filter bolt is exactly the same thread. I wouldn't use it for hte job...but it was easy to measure it and it is indeed M20 x 1.5 and screws into the thread. With the bolt out, I could see exactly what you meant. I will go and hunt a bit to see what I can get hold of to do the job :)
Peter ...everything these days is plus postage :)
But....I know I need a bundle of things, and postage is one of those things that get easier to bear when you buy more.
Currently I am trying to find a diplomatic way of explaining to the missus that the head is going to need an overhaul, with new valve guides, probably new valves and having the seats looked at. Then there is the possible need to sort the cam carriers. Haven't looked at the crank yet....but I can already see £500 in bills

Contact a member Paul G, i thick he bought a few bolts to get the fly wheel off.
If you need the valve seat done, do not let any engineer cut them. They like to be ground ;)
And if the valve guides need replacing, then you will need the head skimmed. All this will need doing after any paint .

Trigger...thanks for that. I definitely want the valve seats done, as they are not sealing like they should. It also seems silly NOT to swap out the valve guides while everything is torn down. Of course...they may be perfectly fine....but I have had several people tell me the exhaust valves are poor on these motors. With unknown mileage on the motor I don;t want to leave things that could result in a smokey, rattley motor.
Also...I would have painted the head AFTER I got the work done. I suppose it's better to paint then skim, so you don't have to worry about paint getting in the way and you know the surface won;t have paint ridges to cause sealing issues. Need a guy to do the work who won't scratch the paint :)

Weird that in respect that the original tools in the front of the manual show cutters not the grinding machine we ended up using, never thought of that before.

That is a bit strange as was never sent cutters from Honda, only the grinding machine which i still have ;)
I have seen engineers try to use a Serdi valve machine and make a right mess >:(

Been a slow progress week.....so no pretty pictures to show for a few days.
Not been idle...but the pace has slowed.
I needed to go back througfh the bits pile, bag up, store and tidy the stuff I had dismantled. The cams were wrapped in clean rags, given an oil bath and then taped up in some thick plastic bags. Same for the cam towers, the head and the barrels. All the nuts and bolts have been freezer bagged, labelled and boxed up. It's made things a bit easier in terms of storage!
All the engine covers have been removed and I plan a visit to the family in a week or so. Dad has a stock of US spec paint stripper which I plan to raid. Stripper that still has hte old magic ingredient that strips paint...which apparantly is far too dangerous for us to use nowadays. He also has a small blasting cabinet. Going to take some sample parts down ( they are in Somerset...I'm in London....nice and local eh? ) and see how well I can clean them up.
Got to go out of town next week.....so I got to leave it alone for a whole week ...and just shop for bits ;)
