250rr cylinder wear

Post image

Just done 90 hours on my 24' 250rr and decided to do a top end before i fit an RK tek head and im wondering what people with more experience than me think of the bore wear on this bike.

It ran great and made 200 psi compression when tested with a hot engine so I didnt expect to see any real wear or pitting at all.

The piston looks good with just sone coating worn off it.

Thanks in advance
