So this is a picture of the cylinder wall... is this little fingernail deep scratch the reason I'm only building up 30 psi? And if you can include how sure/positive you are, that would be insightful.

Give me a quick opinion after looking at this picture...

Yes, that's probably why. 95% sure. The 5% reserved for the condition of your reed valves.

Most of my money is spent on scooterparts. The rest is just wasted.

Possibly a piston, but you can't tell from the picture. Kinda hard to tell though, without pulling the cylinder off first. Alot of times the piston can be reused, but if it has any cracks in it or if any bits have broken off, it's gotta go.bp4131018 wrote:Is the jug saveable via a hone or bore?

It will need to be bored for a larger piston, you will need oversize piston, rings to match and head, exhaust and base gaskets. Along with machine work to fit the piston to the bore.
I am not a mechanic, nor do I play one on TV. Actually my advice is probably worth slightly less than what you pay to view it.
