I thought splitting and assembling the cases would be more of a job then it actually was.
You are going this far, why not go the whole way?
Why not indeed.

What makes me laugh is the fact that this engine had excellent compression before the teardown (160psi across all four), and the only real reason for pulling the head off was to repair a stripped spark plug thread.  Now look where I am!  Balls deep and staring into another rabbit hole.  Well, f*ck it.

For some reason or another I thought splitting the cases required specialized tools, clamps, god knows what.  But having had a decent look at the Clymers and after some schooling on another forum, I think I may have been over-egging my omelette somewhat.  No walk in the park, but not as difficult as perhaps I thought.  Not only would it obviously make the exhaust cam chain replacement much simpler, but no doubt there will be plenty of other things for me to check and empty my wallet onto yet again.

That said - what would be the must-do things to check for, and what can be left alone?  How deep need this particular rabbit hole go...?

You pulled this thing apart to fix a stripped spark plug thread?  I just do it while it's all together.  LOL

Yeah, LOL it up mate.  You're not the only one.  ;D

I'd be selling myself short if a stripped thread was indeed the only reason.  I'm also thoroughly curious by nature, and can't leave well enough alone.  I like learning new stuff and getting my hands fucking filthy in the process.  In that regard, I'm not disappointing myself.

Yeah no that's pretty much the sum of it.  Any or all of the above are almost guaranteed - but if I can get in and out with only one of those things then I'm ok with that  8)

I, for one, am glad you pulled it apart and went with a ripping bore.  It's going to be a blast.

And I for two.  There's the right way, the wrong way and the way things happen in my garage.  It's kind of a mash-up of sense, self-doubt, naive enthusiasm and camouflaged creativity. 

And beer. It’s for courage, honest.

Call came in from the machine shop - block is bored and honed, fins fixed (I hope).  Will duck out later today and pick the thing up.  Meanwhile, debate is raging over these cam chains.  I'm definitely steering now towards splitting the cases and simply slipping on an endless chain - while I'm in there there are a few other things I can check and replace like the damping rubbers on the primary shaft, a few seals and o rings.  Anything else that is a definite must-do while I'm in there? 

Feel like I'm my own Cousteau - plumbing depths never before explored.  In my garage anyway.  It's the new frontier.

Tear it down mate. Might as well! All you need is a deadblow mallet and some Yama/Hondabond
