Honda-SOHC

Maybe not Ted, but I can’t find any helpful content posted by this guy which leads me to believe he signed up just to sell stuff.

If that’s the case, he should at least donate to the upkeep.

Its been a pretty good morning so far. Head and barrels now removed and time for a rest and some tea. Just a couple of worries along the way: 1) I only have 11 head bolt washers, not 12 so where is the 12th, was there ever a 12th? ( I have used an inspection lamp to look down the cam chain tunnel and I cant see anything in there, I have given the head a good shake and it hasnt fallen out. 2) the screwdriver slot on the cam chain tensioner adjuster screw is stripped out/snapped off. Waiting for my son to come round later this morning to help remove the forks.

I was hoping that Ted!

Well done Mike always rewarding when you overcome such obstacles - the Cylinder head was a swine to remove on my 400.

As you have the engine out it should be easier to get releasing fluid everywhere before you start.
I have found you need plenty of time for such penetrants to soak through not a quick process.
It might be a consideration to look at ways you might be able to get gravity to help so that the weight of the head itself helps.
Just wondered is there is a way to support the engine upside down on wooden blocks or similar?

It's slightly different subject area - my carb sliders took well over 24 hours of petrol & other solvents to work in a closed container, all four of my carbs were stuck solid. The last one did not yield until three or four days believe it or not. The good news is new they eventually freed off without damage of any kind.

Maybe remove  the tappets and refit the covers minus o rings to give you another handy place to knock. Or if want replace them ( very cheap ) partially screw them in leaving a lip to drive against taking care to protect the valve cover edge. Haven’t tried this but it might be worth investigating.
