Those cylinder walls look good to you? You should look at your picture and zoom in on the vertical gouge on #1 , deep double rust scars on #4 ,and at least one rust scar that I can see well from here in #3 .
feel smooth??? The PO probably honed the living #$%* out of them, at this point it doesn't matter how smooth they feel , are they egg shaped, are they within tolerances and serviceable with the rings and pistons that you are using?They are probably the original rings. Do you already have piston slap? What's the skirts look like. Did you measure anything here to see if it was within tolerance and serviceable before deciding to put it back together? and together wrong.
Read the manual, understand the manual , you will find most everything you will ever need to know and how to do it in the manual. don't read the manual and you are doomed to fail.
Removing the same #$%*ty parts and reassembling it with those same #$%*ty parts is insanity, you will never have a decent running machine that way .
It's just a waste of time, your time and mine . See ya.
