Hi Phillip
The rebuild was not planned as the guy that sold the boat lied. I blame myself partially for not checking properly. Rookie mistake. As for the rebuild, it was a good experience and it cost me about 3k in parts and some labor (cyl bore, bearing press...) I also had to replace the flywheel, 1head, 2 rods and the starter. If I had to, I would do it again. The saving is about 2500$ for doing it yourself. Just take your time and don't rush anything. Also having the support from Dr. Honda and the forum was a key ingredient. 110 psi seems pretty good to me. I'm no expert but these engines are known to run even at 90. Perhaps a home and a new set of rings would do the trick for yours but that's just an opinion. I'll leave it to the experts. Good luck
