Thanks for the info terry, andy and everybody else so far.
I pulled the cylinder up off the pistons, (required more force than I would have thought to get it loose) also I think it's kind of vague in the manuals I have when to take the cam chain tensioner and cam chain guide off. It's after the cylinder comes off, the tensioner comes off from the top of the crankcase and the chain guide comes off from the bottom of the cylinder.
Also I removed the Valves from the cylinder head, using a different style tool than in the guides:
http://autorepair.about.com/library/images/bl254a-lib.htmsee K-D Tools P/N KD 3271 in the middle there. It was a bit of a hassle, putting the spring down and then getting those half moon clips off the guides (any worldly wisdom on that?)
Two of the valves required a little force to get out of their guides (again the ones closest to my oil starvation problem) but they seem pretty true, straight and tight in the guides.
so here's some pictures of them (the roughest one is on the right):
Here's and average valve seat:
Here's the worst one in the head:
and here's some of the cylinders and a piston (they are all looking about the same)
In the next installment: pistons come off, and into the crankcase!
Any suggestions about the condition of those valves and pistons/bores would be appreciated, also any information about cleaning up the inside of a valve guide (I would like to avoid getting into replacing valves and seals and such if I can avoid it)
