Nothing wrong with a reminder like that, keep 'em comin in case I over look something.
But yes, rotor 3.9 ohms between the slip rings and the stator checks 0.7 between each leg (3 yellow wires), infinite to ground on each.

I put ATF thinned with kerosene in the combustion chambers to check for the vales seating properly, slight moisture grew in various ports overnight.

So after disassembling the head, I used Marvel Mystery Oil and a brass brush to clean the combustion chambers and the intake / exhaust runners. Then lapped the valves by hand to get rid of the slight pitting(ugh!). But the seats and valve face turned out nice.
Did a quick cylinder hone on the jugs... yes, I know it's not a Hardley and they are called "Cylinders" but I like saying "jugs" ( Freud would have a hay-day in my head... jugs, Jugs, JUGS!)


I found a OEM Honda gasket set "A" on e-bay for less that the dealership wanted for the head gasket alone. Pistons and cylinders miced out withing the service limits so I instailed the base gasket and jugs (there's that word again). Badda-Bing Badda-Boom we are in business.
